Audio Hijack

vertical specialist

macOS audio routing application that captures and applies gain effects to audio from individual applications.

9.3/10
Overall
Features9.3/10
Ease of Use9.1/10
Value9.4/10
Standout feature

Block-based session graphs let each capture, DSP chain, and output run as a saved audio workflow.

Audio Hijack captures audio with selectable source blocks and drives a digital signal processing pipeline made of discrete processing blocks like EQ, amplification, limiting, and dynamic effects. Each session can define its own signal path so different boosting targets can run side-by-side without changing system settings. The app includes monitoring and level indication to help tune gain staging and avoid output clipping during louder playback.

A key tradeoff is that Audio Hijack is macOS-focused and the block graph needs configuration for each use case, so ad-hoc switching between many sources can require session management. It fits best when a single boosted output target is used repeatedly, such as podcast recording chains or a fixed monitoring mix for streaming.

Pros
  • +Block-based DSP chain makes gain staging and EQ repeatable
  • +Session-defined routing enables multiple independent processing paths
  • +Real-time metering supports limiting decisions to prevent clipping
  • +Flexible output options support both playback and recording
Cons
  • –Requires macOS and cannot replace PC routing workflows
  • –Switching many dynamic scenarios needs multiple sessions
  • –Graph configuration can be slower than simple system volume boosts

#2

Bongiovi DPS

consumer desktop

Audio processing software that enhances clarity, loudness, and tonal balance across playback devices.

8.9/10
Overall
Features8.8/10
Ease of Use8.9/10
Value9.2/10
Standout feature

DPS applies its audio processing chain as a listener-side system hook for continuous loudness leveling.

Bongiovi DPS focuses on music and media playback rather than routing complexity. It exposes loudness and tonality controls that influence pre-amplification gain staging and dynamic range behavior during playback. The app also includes an audio limiter control point to reduce output overs when peaks would otherwise clip.

A key tradeoff is that deeper routing and per-application capture control are limited compared with pro toolchains that offer explicit endpoint routing or loopback capture. It fits when one computer streams the same source to the same speakers or headset and consistent loudness matters more than granular session-level control.

Pros
  • +System-level processing for everyday media playback loudness control
  • +Built-in limiter behavior helps prevent obvious output clipping
  • +Easy-to-configure tone and gain controls without external routing tools
  • +Consistent settings profile across typical output devices
Cons
  • –Limited per-application audio interception compared with DSP routing apps
  • –Advanced pipeline tuning and filter editing are not granular
  • –Performance impact can appear on lower-power systems
  • –Does not replace a full mixer style workflow for multi-source mixing

Best for: Fits when one workstation needs consistent, safer loudness on speakers or headphones.

#3

Voicemeeter

vertical specialist

Virtual audio mixer for Windows that provides input gain staging and routing across multiple virtual and hardware channels.

8.7/10
Overall
Features8.9/10
Ease of Use8.4/10
Value8.6/10
Standout feature

Hardware-agnostic mixer routing that maps virtual inputs to selectable outputs with editable level and processing per channel.

Voicemeeter exposes routing that can mix multiple inputs into independent output buses with adjustable levels, panning, and effect blocks. The workflow centers on configuring a digital signal processing pipeline using virtual I/O and driver-level audio capture paths. Routing behavior and latency depend on the selected audio subsystem and buffer sizing, which changes how quickly monitoring reacts. For loud playback, it can apply dynamics and EQ blocks, but it does not behave like a one-click loudness normalizer geared for LUFS compliance.

A common tradeoff is that routing changes can disrupt monitoring if endpoints and buffer sizes are mismatched. It fits scenarios where repeatable routing logic matters, like redirecting microphone plus system audio to stream software or remapping headphone and capture outputs. It is less suitable for teams that need a fixed, policy-driven audio profile with minimal operator involvement, because the configuration is largely manual and stateful in the mixer UI.

Pros
  • +Multi-bus matrix routing supports complex input-to-output mixes
  • +Configurable per-channel DSP chain for EQ and dynamics
  • +Loopback capture enables mixing app audio with mic monitoring
  • +ASIO endpoint routing can reduce latency for supported devices
Cons
  • –Routing and buffer settings are fragile when endpoints change
  • –Mac support is limited compared to Windows driver workflows
  • –No built-in loudness normalization workflow for strict LUFS targets
  • –DSP tuning requires ear-led iteration to avoid clipping artifacts

Value8.3/10
Standout feature

Per-application mixing with automatic routing inside Sonar to apply EQ and gain per program.

SteelSeries Sonar pairs a real-time DSP chain with app-focused routing so different programs can be boosted without manual cable-style patching. It uses WASAPI loopback capture and per-channel processing to adjust loudness targets and tone before audio reaches the selected output.

Sonar focuses on headphone and mic monitoring workflows with separate mixes for game audio and voice capture. Configuration is driven through the Sonar mixer UI and system audio endpoint selection rather than editable DSP graphs.

Pros
  • +Per-app routing in the Sonar mixer reduces need for manual re-patching
  • +Real-time processing for playback and mic monitoring supports focused gain staging
  • +WASAPI loopback capture simplifies loudness adjustments without extra devices
  • +Headphone-focused EQ and output tuning are reachable from one UI
Cons
  • –Requires careful endpoint selection to avoid double processing or wrong outputs
  • –Advanced DSP control is limited compared with mixer-first tools like Voicemeeter
  • –Audio session handling can feel opaque when third-party apps manage their own devices
  • –Effects parameters are less granular for multichannel workflows

Best for: Fits when PC or Mac users want app-level audio boosts and headphone tuning in a single mixer view.

#5

Overall
Features7.9/10
Ease of Use8.1/10
Value7.9/10
Standout feature

System-wide filter insertion controlled through plain-text rules per audio endpoint.

Equalizer APO inserts an audio filter chain system-wide, then applies EQ and other DSP modules per output endpoint. Configuration is driven by an easy-to-edit text ruleset and a Windows tray workflow that reloads on demand.

The software supports detailed equalizer band profiling, channel remapping, and optional use of external components to extend processing stages. Real results depend on careful gain staging and buffer-latency tuning to avoid clipping and unwanted audible artifacts.

Pros
  • +System-wide DSP hook with per-device filter rules
  • +Text-based configuration enables repeatable EQ and routing setups
  • +Channel remapping matrix supports nonstandard headphone layouts
  • +External module support expands beyond stock EQ blocks
Cons
  • –Setup requires Windows audio driver understanding and careful gain staging
  • –No built-in loudness normalization or loudness metering workflow

Best for: Fits when precise, endpoint-specific EQ and routing are needed for PC listening and production monitoring.

#6

Overall
Features7.6/10
Ease of Use7.7/10
Value7.7/10
Standout feature

Per-app equalizer profiles with output headroom controls designed to keep boosted playback from clipping.

Equalizer Pro targets PC and Mac users who want a system-wide audio booster effect with per-app control of a digital signal processing pipeline. It provides an equalizer-style interface plus gain staging controls aimed at improving perceived loudness without changing the source encoding.

The workflow is built around routing audio through its processing engine and managing output headroom to reduce obvious clipping artifacts. It is less suitable for users who need deep ASIO endpoint routing or custom DSP chain insertion in every playback stack.

Pros
  • +Simple booster controls with an audible effect preview workflow
  • +Per-application targeting for tuning voice, music, and video playback
  • +Headroom-oriented output control to limit harsh distortion during boost
  • +Mac and PC builds support the same core EQ-style adjustments
Cons

7.3/10
Overall
Features7.2/10
Ease of Use7.5/10
Value7.3/10
Standout feature

User-controlled amplification with built-in clipping mitigation tuned for phone speakers and basic playback.

Volume Booster GOODEV focuses on raising perceived loudness for Android audio by applying a user-controlled amplification stage before output. It runs as a device-side utility that pairs a simple gain control with limits intended to reduce harsh clipping.

The app targets everyday media playback and meeting-app audio rather than offering a full digital signal processing pipeline with routing and per-app DSP. Compared with desktop tools that offer endpoint routing and session-level control, its control surface stays narrow and mostly gain-based.

Pros
  • +Simple amplification slider with immediate audible effect
  • +Limiter-style behavior helps prevent the worst output clipping
Cons
  • –Limited control over per-app audio sessions and routing
  • –DSP chain depth is mostly gain-based, not multi-stage equalization

Best for: Fits when loudness needs matter on Android for media and calls without complex audio routing.

#8

Poweramp Equalizer

Standout feature

Poweramp Equalizer’s preset workflow keeps equalizer band profiling consistent across sessions.

Poweramp Equalizer provides a parameter-driven equalizer with presets, fine-grained band control, and per-output gain adjustment through a dedicated DSP chain. Its core capability is shaping the digital signal processing pipeline with multi-band EQ, optional dynamics-style options, and loudness-oriented listening presets.

The app focuses on the equalizer layer rather than system-wide audio capture or routing across apps. Poweramp Equalizer is typically used for consistent tone changes, not for building a complex, multi-app DSP graph.

Pros
  • +Multi-band equalizer with adjustable frequency and gain per band
  • +Preset management supports quick A/B switching for different playback sources
  • +Simple output gain control helps avoid obvious under- or over-leveling
  • +DSP stays within the Poweramp Equalizer workflow for predictable results
Cons
  • –Not a system-wide audio hook driver or endpoint wrapper for all apps
  • –Limited control over ASIO endpoint routing and per-application DSP boundaries
  • –No exposed API surface for automation or external configuration control
  • –Complex tuning takes multiple passes to avoid tonal imbalance

Best for: Fits when a single playback app needs repeatable EQ tuning without system-wide routing changes.

How to Choose the Right sound booster software

Sound booster software changes perceived loudness by inserting EQ, gain staging, and limiter behavior into a digital signal processing pipeline that runs during playback or monitoring. This buyer’s guide covers Audio Hijack, Bongiovi DPS, Voicemeeter, SteelSeries Sonar, Equalizer APO, Equalizer Pro, Volume Booster GOODEV, Poweramp Equalizer, eqMac, and Fidelizer for PC and Mac users.

The tools vary by how they intercept audio, from Audio Hijack’s saved block-based session graphs to Equalizer APO’s plain-text system-wide endpoint rules. The rest of the guide prioritizes integration depth, configuration repeatability, and automation surface, since per-app mixing and system-level hooks demand different operational discipline.

Sound booster software that boosts volume with EQ, gain staging, and limiting via routing or system-wide DSP hooks

Sound booster software increases loudness by shaping frequency balance with equalizer bands and controlling peaks with limiter behavior, which helps boosted playback avoid output clipping. Many options also support repeatable tuning through saved profiles, session workflows, or per-endpoint configuration rules that keep gain staging consistent.

Audio Hijack on macOS uses block-based session graphs so each capture, DSP chain, and output can run as a saved workflow, which suits repeatable loudness boosting across scenarios. Equalizer APO on Windows inserts DSP filters through system-wide endpoint rules, which supports precise per-device EQ and routing without per-app setup but requires careful gain staging discipline to avoid overs.

Sound booster evaluation criteria that affect loudness, routing, and repeatability

Sound booster software changes loudness by shaping a DSP pipeline with EQ, gain staging, and limiter behavior, so the evaluation needs to follow how audio is intercepted and processed. Tools that route per-app or per-session reduce accidental double-processing because each path has a defined scope for gain and limiting.

Repeatability matters more than raw gain numbers because boosting without controlled limiter behavior increases output clipping risk, including inter-sample overs. Repeatable workflows and configuration formats help avoid drifting settings across endpoints, sessions, and listening devices.

  • Interception scope and routing boundaries

    Audio Hijack targets macOS workflows through saved session graphs, while Equalizer APO applies system-wide DSP insertion via plain-text endpoint rules on Windows. These scopes determine whether the same boost settings run for every app or only within a specific capture path.

  • Limiter and clipping behavior controllability

    Bongiovi DPS applies its loudness leveling and limiter behavior as a listener-side system hook for continuous playback, while Equalizer Pro focuses on booster profiles with output headroom controls intended to prevent clipping. The key difference is how transparent the limiter behavior is for tuning and how often users need to iterate to avoid overs.

  • Configuration repeatability and workflow portability

    Audio Hijack saves block-based DSP chain sessions, which makes gain staging and EQ repeatable across scenarios on macOS. Equalizer APO uses text-based configuration rules per audio endpoint, which supports repeatable setups when moving between machines or changing devices.

  • DSP granularity per channel or per app

    Voicemeeter exposes a multi-bus matrix that maps virtual inputs to selectable outputs with editable per-channel processing, which suits live monitoring and streaming. SteelSeries Sonar adds per-application mixing inside its Sonar mixer view, which reduces manual re-patching when tuning boosts per app.

  • Practical endpoint fragility and change resilience

    Voicemeeter routing and buffer settings can become fragile when endpoints change, which can break the intended signal path during hardware swaps. Equalizer APO remains rule-based per endpoint on Windows, which keeps behavior stable when endpoints are renamed or reinstalled.

Choose based on where the boost runs and how settings stay consistent

The first decision is how the tool intercepts audio, because interception scope defines whether loudness leveling happens for everything or only for specific apps or sessions. Audio booster behavior can diverge sharply between mixer-first routing tools and endpoint-filter tools.

The second decision is whether the workflow needs repeatable automation, because users often tune once and then change apps, devices, or scenarios. Tools with saved session graphs or text-based endpoint rules reduce drift and make gain staging safer to maintain.

  • Pick interception scope: workflow, per-app, or endpoint-wide

    Choose Audio Hijack when saved workflow runs are the unit of control on macOS, because each capture and DSP chain becomes a reusable session. Choose Equalizer APO when endpoint-specific filter rules must apply system-wide on Windows, because the DSP insertion is controlled through plain-text rules per device.

  • Match the tuning workflow to your daily scenarios

    Choose Voicemeeter when live desktop routing and custom DSP are needed for streaming and monitoring, because it uses virtual inputs and a multi-bus matrix with per-channel DSP chain editing. Choose SteelSeries Sonar when per-application boosts and mic monitoring need a single mixer view, because Sonar routes and processes inside its mixer.

  • Select limiter transparency based on how much tuning control is required

    Choose Equalizer Pro when users want simple per-app booster profiles with output headroom controls, because the tool is designed around keeping boosted playback from clipping. Choose Bongiovi DPS when one continuous listener-side loudness leveling loop is preferred, because its limiter behavior is embedded in the hook-based processing.

  • Use configuration portability to reduce setup drift across devices

    Choose Audio Hijack when saved block-based session graphs must travel with the same DSP layout across macOS scenarios. Choose Equalizer APO when repeatability must be expressed as editable rules per audio endpoint, because that format supports versioned changes and controlled reruns.

  • Verify endpoint change resilience for the intended hardware

    Choose Voicemeeter only when endpoint changes are manageable, because routing and buffer settings can break when endpoints change under Windows. Choose eqMac when a persistent macOS system-wide injection is the goal, because it uses a kernel-level audio interception model to apply one DSP chain across playback.

  • Choose a headphone-first pipeline only when the listening scope is narrow

    Choose Fidelizer when headphone listeners want a single loudness-and-EQ pipeline with profile-based presets and integrated limiting. Choose eqMac when the goal is persistent system-wide playback processing for headphones, because it applies one DSP chain without per-app routing setup.

Who benefits from sound booster software with DSP hooks, routing mixers, or saved sessions

Sound booster software fits best when loudness changes must be controlled at the signal path level instead of only in a single player. The right tool depends on whether boosts must apply per app, per workflow, or system-wide across endpoints.

Different products also match different risk tolerances, because some pipelines bake in limiter behavior for safer everyday playback while others require careful gain staging to avoid inter-sample peak overs.

  • Mac users who need repeatable EQ and gain staging per workflow

    Audio Hijack provides block-based session graphs on macOS so each capture and DSP chain becomes a saved workflow rather than a one-off knob setting.

  • PC streamers and monitors who need custom multi-input to multi-output routing

    Voicemeeter supports hardware-agnostic virtual routing and a multi-bus matrix so live monitoring and DSP per channel can match the streaming setup.

  • Windows listeners who want endpoint-specific EQ rules without per-app setup

    Equalizer APO inserts DSP through system-wide endpoint rules on Windows so the same filter chain can apply to selected devices even when apps change.

  • Users who want one continuous loudness leveling behavior during playback

    Bongiovi DPS applies its processing as a listener-side system hook so the same loudness strategy runs across everyday media playback.

  • Headphone listeners who want a single loudness and EQ pipeline

    Fidelizer and eqMac both bias toward headphone-first listening because their pipelines are designed around consistent playback processing without detailed per-app routing.

Common pitfalls that cause clipping, inconsistent loudness, or broken routing

Sound booster setups often fail when gain staging is treated as a single slider problem instead of a DSP pipeline problem. Routing scope mismatches also cause double processing, which can push peaks into clipping even when a limiter seems present.

Another common failure is using a tool outside its intended interception model, because kernel-level system hooks and driver-level endpoint filters behave differently when endpoints change or when apps create new audio sessions.

  • Boosting with no repeatable limiter or headroom strategy across sessions

    Equalizer Pro provides output headroom controls for boosted playback, while Bongiovi DPS bakes limiting into its loudness leveling hook, so choose a tool whose limiter behavior matches the tuning workflow.

  • Configuring per-app boosts and then applying an endpoint-wide DSP filter at the same time

    SteelSeries Sonar’s per-application routing can double-process if system-wide DSP is also active, so pick either an app-scoped mixer path or an endpoint-filter path.

  • Ignoring endpoint change fragility in routing-first mixers

    Voicemeeter can become fragile when endpoints change, so test after device swaps and keep routing buffers stable for the expected hardware lifecycle.

  • Using a headphone-focused pipeline for speakers without retuning

    Fidelizer is headphone oriented, so speakers often need a different EQ and gain staging approach to avoid odd tonal balance and unexpected peak behavior.

  • Assuming system-wide DSP on Windows matches macOS system injection behavior

    Equalizer APO uses plain-text endpoint rules on Windows, while eqMac uses kernel-level audio interception on macOS, so the same configuration mindset does not transfer directly.

How We Selected and Ranked These Tools

We evaluated how each sound booster inserts DSP into the audio pipeline using real mechanisms like saved block-based session graphs in Audio Hijack and plain-text endpoint rules in Equalizer APO. We scored features by scope control, routing granularity, and how much users can repeat gain staging and limiting behavior without rework.

We scored ease and value based on day-to-day configuration friction, including how often endpoint selection or routing buffers require attention. Audio Hijack separated itself by making block-based session workflows the core unit of control on macOS, which keeps each capture DSP chain and output path repeatable while still allowing scenario-specific tuning.

Frequently Asked Questions About sound booster software

How does Audio Hijack differ from Equalizer APO for system-wide sound boosting on macOS and Windows?
Audio Hijack builds a saved, block-based DSP workflow by routing sources into processing stages and defined outputs, with real-time metering and monitoring. Equalizer APO inserts filter modules system-wide per Windows output endpoint using a plain-text ruleset, then reloads the chain from the tray without a saved DSP graph.
Which tool is better for per-application boosts using an internal mixer view instead of editing routing graphs?
SteelSeries Sonar applies EQ and gain adjustments inside its app-focused mixer, using program selection and system audio endpoint selection to target different applications. Equalizer Pro and Fidelizer apply broader playback pipelines, with Equalizer Pro offering per-app profiles and Fidelizer using a single selectable headphone-first pipeline rather than separate per-program mixes.
When is Voicemeeter the practical choice for live desktop audio routing and monitoring?
Voicemeeter fits when live desktop audio, mic, and loopback capture must be remapped through a matrix-style mixer with editable per-channel DSP chains. Audio Hijack targets repeatable macOS workflows as saved graphs, while SteelSeries Sonar emphasizes app-level mixing in its UI rather than multi-input routing across a virtual mixer.
What breaks if gain staging is ignored when using Equalizer APO or eqMac?
Equalizer APO can clip if boost amounts push output above safe headroom after EQ bands, and inter-stage levels are not managed in the ruleset. eqMac includes limiter-style stages aimed at output clipping prevention, but incorrect processing order or excessive amplification can still reduce decibel headroom margin and produce distortion.
How do Bongiovi DPS and Fidelizer handle loudness consistency, and where do they differ?
Bongiovi DPS targets listener-side loudness control by applying its real-time DSP chain as a system hook with settings per output device, focusing on automatic gain management and shaping. Fidelizer ships an integrated loudness and EQ workflow that swaps into a headphone-first DSP pipeline, which is simpler than building separate loudness targets per device.
Which setup is more suitable for endpoint-specific EQ and channel remapping on Windows systems?
Equalizer APO is designed for endpoint-specific filter insertion and supports channel remapping matrix use through its module-based chain. Voicemeeter can also route and process, but it is primarily a virtual mixer approach that depends on configuring inputs and outputs in the software mixer rather than maintaining endpoint rules.
How does equalizer extensibility compare between Audio Hijack and Equalizer Pro for custom DSP workflows?
Audio Hijack uses a block-based session graph, so each stage in the DSP chain can be configured as a distinct block within the workflow. Equalizer Pro provides a system-wide boosted sound profile with per-app controls and output headroom controls, which limits deep custom chain insertion compared with graph-based routing.
When does eqMac fall short for PC-style cross-app virtual device switching and routing scenarios?
eqMac mainly covers macOS playback paths through its system-wide hook driver, so it focuses on consistent EQ and gain staging without offering full cross-app virtual device switching like Voicemeeter. SteelSeries Sonar also emphasizes endpoint and program selection inside its own mixer, but it is designed around those app-routing workflows rather than PC-style virtual mixer graphs.
What tradeoff shows up when choosing Volume Booster GOODEV over desktop DSP tools like Poweramp Equalizer?
Volume Booster GOODEV is a narrow gain-based utility for Android media and meeting-app audio, so it does not provide multi-app routing or a configurable DSP chain comparable to desktop systems. Poweramp Equalizer targets a parameter-driven EQ with multi-band control inside the playback app, so it supports consistent tone shaping without relying on system-wide hooks.

    You appear in the roundup the same way as other tools we cover: name, positioning, and a clear next step for readers who want to learn more.

  • Kept up to date

    We refresh lists on a regular rhythm so the category page stays useful as products and pricing change.
