Standout feature

Wi-Fi audio streaming from a desktop SoundWire Server to Android phones and tablets.

SoundWire captures the computer's active audio stream and forwards it to one or more nearby Android devices through the local network. Users can place an Android phone near remote speakers, connect headphones to a tablet, or use an older handset as a listening endpoint. Server controls cover the source stream, compression, and buffer behavior.

The tradeoff is limited routing depth because SoundWire mirrors the computer's audio rather than assigning separate applications to different outputs. It fits a room where desktop audio needs to reach wireless headphones or a second speaker location without moving the computer.

Pros
  • +Streams desktop audio to Android phones and tablets over a local Wi-Fi network
  • +Works with Windows and Linux desktop servers
  • +Supports adjustable buffering for different network conditions
  • +Uses existing Android headphones, speakers, and device outputs
Cons
  • Android is required for the receiving device
  • Does not assign individual applications to separate outputs

How to Choose the Right dual audio output software

Dual audio output software routes the same audio stream to multiple output devices while also supporting per-application output targeting and channel mapping. This buyer’s guide covers SoundWire, SteelSeries Sonar, NVIDIA Broadcast, BlackHole, Loopback, EarTrumpet, Voicemeeter, Virtual Audio Cable, PipeWire, and SoundSource to match different routing workflows.

SoundWire reaches Android receivers over local Wi-Fi from a desktop server. SteelSeries Sonar targets Windows gamers with five separate Sonar paths for Game, Chat, Media, Aux, and Stream. The remaining tools span macOS mixer graphs, Windows session switching, virtual endpoint pairing, and system-level graph routing.

Dual audio output software that duplicates and routes audio to multiple devices

Dual audio output software uses virtual endpoints, routing graphs, or session-level controls to send playback to more than one destination at the same time. Some tools focus on duplication via paired endpoints like BlackHole and Virtual Audio Cable so host apps can select devices from standard OS menus. Other tools build a fuller mixer and routing layer like Loopback that supports per-application routing into multiple virtual outputs with channel mapping.

The practical difference between tools shows up in how they assign sources to outputs. EarTrumpet targets a single Windows workstation with an interactive session list that routes currently playing processes to a chosen output. PipeWire provides graph-based policy routing that coordinates streams across applications and devices, which changes how advanced latency tuning and routing consistency are handled.

Dual audio output capabilities to compare across routing and control layers

Dual audio output software needs a repeatable path from source to destination so the same playback can land on multiple devices without manual per-app device swapping. Tools differ most in how they structure sources, outputs, and routing decisions for duplication and simultaneous playback.

  • Application-level output assignment and session awareness

    SteelSeries Sonar assigns individual applications into five Sonar paths like Game, Chat, Media, Aux, and Stream on Windows. EarTrumpet routes based on the currently playing process list so changes are tied to live audio sessions on a single workstation.

  • Dual-output duplication via paired virtual endpoints

    BlackHole presents a paired virtual endpoint setup that supports direct dual-output duplication using standard audio device selection. Virtual Audio Cable provides driver-level virtual cable endpoints for predictable left-right handling and loopback recapture by other apps.

  • Routing graph control and channel mapping depth

    Loopback supports per-application routing into multiple virtual outputs with separate mixing controls and channel mapping for stereo left-right or mono aggregation workflows. PipeWire uses graph-based routing that coordinates multi-output duplication across applications while also handling ALSA and PulseAudio clients together.

  • Mixer topology for simultaneous multi-device outputs

    Voicemeeter uses a bus-based mixer layout that drives duplicated output to separate destinations with per-channel gain and mute controls. Virtual Audio Cable stays closer to virtual endpoint routing and offers limited mixer topology versus a full matrix mixer.

  • Routing scope and platform coverage boundaries

    SoundWire streams desktop audio to Android phones and tablets over local Wi-Fi and requires Android on the receiving device. SteelSeries Sonar runs Windows-only and targets gamer monitoring workflows rather than cross-platform routing.

  • Automation surface for repeatable routing changes

    PipeWire’s graph routing and policy-based stream routing support consistent coordination across apps during routing changes. SoundSource lacks a documented external automation API for programmatic route changes, which shifts changes toward manual interaction on macOS.

Choose by routing model: endpoint pairing, session control, or graph-based policy

Start by matching the routing model to the workflow that needs simultaneous outputs. Endpoint pairing tools reduce complexity by relying on standard OS device selection, while mixer and graph tools provide controllable routing when multiple apps must land on multiple destinations.

  • Pick an endpoint-pairing workflow when dual output must be chosen in standard device menus

    BlackHole fits when two virtual endpoints should appear as standard selectable devices for direct audio duplication without adding a mixer layer. Virtual Audio Cable fits when a routed playback stream must be recaptured by other apps through driver-level virtual endpoints with predictable left-right handling.

  • Pick session-first routing when a single Windows workstation needs quick per-app reroutes

    EarTrumpet fits when routing changes should be driven by the session list that reflects currently playing processes. SteelSeries Sonar fits when Windows gamers need per-application monitoring paths across Game, Chat, Media, Aux, and Stream.

  • Pick graph-based routing when simultaneous multi-output must stay consistent across multiple apps

    PipeWire fits when a graph-based router must coordinate stream routing and keep latency behavior consistent across applications and devices. Loopback fits when per-application routing requires a mixer-like graph with channel mapping and separate mixing controls.

  • Pick a bus-based mixer when independent gains and mutes need to stay visible across duplicated destinations

    Voicemeeter fits when a bus-based mixer layout must drive simultaneous multi-device output with per-channel gain and mute controls. NVIDIA Broadcast fits when clean audio capture is the priority, because it focuses on AI noise removal and echo removal instead of a channel matrix or per-output duplication.

  • Pick a streaming receiver workflow when the second destination is a remote Android device over Wi-Fi

    SoundWire fits when desktop audio must reach Android headphones or speakers in another nearby location over local Wi-Fi using a SoundWire Server. Tools like BlackHole and Virtual Audio Cable assume local host selection of virtual endpoints instead of Android Wi-Fi receivers.

Who benefits from these dual audio output models

Dual audio output tools divide into clear user groups based on whether the second destination is remote, a local second device, or a virtual endpoint feeding other apps. Teams and individuals also differ in whether they need per-app routing decisions or channel mapping with a controllable routing graph.

  • Windows gamers who want separate monitoring paths per program

    SteelSeries Sonar assigns individual applications into five Sonar channels like Game and Chat so monitoring can match what each program is doing. EarTrumpet can also route by session, but Sonar’s fixed path model better supports gamer monitoring workflows.

  • macOS users building meetings, recording, and monitoring mixes from multiple apps

    Loopback supports per-application routing into multiple virtual outputs with channel mapping for stereo left-right or mono aggregation. SoundSource supports simultaneous multi-output duplication per-app on macOS, but it lacks a documented external automation API.

  • Users duplicating audio into a second local endpoint for other applications to process

    BlackHole provides a paired virtual endpoint setup designed for direct dual-output duplication using standard OS device selection. Virtual Audio Cable provides loopback virtual cable endpoints so routed playback can be recaptured for processing by other apps.

  • Teams coordinating consistent multi-app routing with predictable latency behavior

    PipeWire uses graph-based routing and unified handling of ALSA and PulseAudio clients, which helps keep stream routing consistent across multiple apps. Loopback supports similar multi-output per-app routing with channel mapping, but its setup focuses on modeling routing graphs to avoid feedback loops.

Common mistakes that derail dual audio output deployments

Most failures come from choosing a tool whose routing scope does not match the second destination type. Other failures come from underestimating the time needed to model routing and prevent feedback loops in graph-based systems.

  • Assuming a tool built for AI microphone cleanup can duplicate speaker audio to multiple physical outputs

    NVIDIA Broadcast focuses on AI Noise Removal and Room Echo Removal and cannot send one source to two physical outputs simultaneously. Selecting it for dual-output speaker duplication will fail because it does not include a channel matrix or per-application volume controls.

  • Expecting virtual endpoint tools to provide per-app routing or automation graphs

    BlackHole and Virtual Audio Cable integrate via standard OS device selection and do not provide built-in mixing or per-application output assignment. Graph-level automation requires tools like PipeWire or Loopback, which represent routing as a controllable graph.

  • Building a complex routing graph without planning for feedback loop avoidance

    Loopback setup takes time to model routing graphs and avoid feedback loops, which blocks immediate results when routing is changed repeatedly. PipeWire’s graph routing also requires learning node graph concepts to tune buffer size and rate configuration without runaway latency.

  • Assuming cross-platform support when the tool is tied to a specific OS audio stack and UI model

    SteelSeries Sonar runs Windows-only and excludes macOS and Linux audio setups. SoundWire requires Android on the receiving device, so using it for local desktop duplication on another OS can’t match the intended workflow.

  • Confusing interactive session routing with duplication and mixing

    EarTrumpet is interactive and routes by the session list of currently playing processes, and it does not provide built-in audio duplication or mixing for multi-device simultaneous output. Voicemeeter and Loopback provide multi-bus or mixer-like topology that supports controlled simultaneous output duplication.

Frequently Asked Questions About dual audio output software

How does per-application output assignment differ between EarTrumpet and SteelSeries Sonar?
EarTrumpet routes per-audio-session playback by selecting a target output for each currently playing process using the Windows audio stack. SteelSeries Sonar instead splits audio into configurable virtual channels like Game, Chat, Media, Aux, and Stream, then targets physical outputs per channel while also supporting EQ presets and channel volume controls.
Which tool provides a stable virtual endpoint pair for direct dual-device duplication on both Windows and macOS?
BlackHole provides a virtual audio device pair designed for direct dual-output duplication. Tools and apps can select BlackHole’s paired endpoints as ordinary OS audio devices, which keeps capture and playback chains consistent without adding an extra mixer layer.
What breaks if two tools both try to take control of the same audio device routing on Windows?
When Voicemeeter and EarTrumpet both attempt to route the same active audio sessions or playback endpoints, the selected routing can change back and forth as each app updates device targets. This can also complicate debugging because the visible active session list in EarTrumpet may not match where Voicemeeter buses are sending audio.
When is SoundWire the right choice for dual audio output across devices?
SoundWire fits when desktop audio needs to play on an Android phone or tablet over Wi-Fi as an additional wireless listening endpoint. It sends desktop audio from the SoundWire Server to Android receivers that output through the device’s headphones, speakers, or built-in output.
Which option targets game monitoring and stream paths without building a full routing matrix?
SteelSeries Sonar targets Windows gamers who need separate monitoring paths for Game, Chat, Media, Aux, and Stream. Its channel strip approach assigns applications into those paths and outputs to selected physical devices with per-channel volume and EQ presets, instead of requiring a full audio matrix workflow.
How do automation workflows differ between Loopback and Voicemeeter?
Loopback supports automation-friendly configuration via command-line launching and repeatable virtual device setups for daily routing workflows on macOS. Voicemeeter uses a desktop app that maps buses to inputs and outputs on Windows, which suits interactive routing and monitoring but is less tailored to scripted repeatability.
What integration gap exists for NVIDIA Broadcast compared with dual-output routing tools?
NVIDIA Broadcast focuses on AI processing for microphone and speaker endpoints used by conferencing and streaming applications. It creates selectable NVIDIA Broadcast microphone and speaker endpoints, but it does not target the same per-application multi-device duplication controls found in Loopback or SoundSource.
Where does sample-rate and latency management typically become the comparison point between PipeWire and Virtual Audio Cable?
PipeWire coordinates routing across apps using its session and stream control primitives, which helps keep latency and format negotiation consistent across multiple destinations. Virtual Audio Cable emphasizes virtual cable endpoints for point-to-point capture and routing, and complex multi-destination scenarios depend more on how those endpoints are chained and recaptured for downstream processing.
Which tool supports re-capturing routed playback into downstream effects by treating it as a re-recordable device?
Virtual Audio Cable supports loopback-style monitoring where routed audio can be re-captured as audio from a virtual device and then played again through separate device targets. BlackHole also acts as a routing endpoint pair, but Virtual Audio Cable’s cable-style re-capture workflow is the clearer fit for chaining effects tools before final playback.
