SteelSeries Sonar
gamingGaming audio software with live AI noise cancellation for microphone input and team chat.
Sonar’s per-application virtual routing sends the same mic through different processing destinations for calls, chat, and stream capture.
SteelSeries Sonar runs as desktop audio software and inserts processing into a virtual device path, which keeps voice capture and conferencing input separate from the system microphone. It pairs noise reduction with call-oriented echo handling so users get fewer distractions in two-way communication. The per-application routing supports different output destinations for game voice, chat apps, and streaming workflows.
A concrete tradeoff is that Sonar depends on using its virtual input devices, so apps that ignore Windows audio device selection cannot benefit without workaround. It fits live voice calls and streaming setups where multiple apps need different processed routes for the same physical microphone.
- +Virtual audio devices route cleaned mic audio per application
- +Call-focused echo handling reduces two-way crosstalk artifacts
- +Real-time monitoring helps tune suppression during use
- +In-session mixing supports multiple audio destinations
- –Apps must select Sonar virtual devices to receive processing
- –Fine-grained DSP parameters are limited versus advanced DSP tools
- –Performance depends on CPU headroom during multi-app capture
- –Routing changes require manual verification in each target app

Best for: Fits when voice calls and streaming need per-app processed mic routing without manual DSP plug-ins.
NVIDIA Broadcast
creatorRTX-based app that applies live noise removal and room echo removal to microphone and speaker audio.
Echo reduction plus microphone denoising delivered through a GPU-accelerated virtual audio device for live apps.
NVIDIA Broadcast applies real-time voice cleanup to the selected microphone input and outputs a processed stream through a virtual audio device that common call apps and streaming software can select. Echo reduction covers two common pain points for live speech, near-end far-end overlap and residual echo that survives basic gating. The capture controls in the Broadcast app let users switch microphones and effect modes while monitoring levels to avoid clipping during effect gain changes.
A key tradeoff is that noise and echo performance depends heavily on using a supported GPU and selecting the correct microphone device profile in the Broadcast app. For PC setups that use a hardware audio interface or routing software, the virtual audio device path can require extra device selection steps so the app uses processed audio instead of the raw input.
- +Virtual audio device output works with standard conferencing and streaming apps
- +GPU-accelerated effects keep processing in real time for live capture
- +Echo reduction and denoising can run together for speech-first environments
- +Per-microphone effect tuning reduces rework when switching input sources
- –Effect quality drops when the GPU requirements are not met
- –Requires careful device routing so apps use the processed virtual input
- –Room acoustics still affect perceived residual artifacts after denoising
- –Some audio chain setups limit fine-grain control over gain staging

Best for: Fits when live voice needs strong local denoising and echo reduction on a supported NVIDIA PC.
Krisp SDK
API-firstDeveloper SDK for embedding live noise cancellation and voice enhancement in apps and devices.
Programmable processing output for embedding into live voice capture and playback flows
Krisp SDK supports programmatic use of microphone denoising for live voice workflows where users expect the processed audio to remain usable in-call and in streaming contexts. The integration model centers on connecting the SDK processing output into an app audio path rather than relying only on a standalone desktop client. This makes it a better fit for teams shipping products like meeting clients, agent-assistance tools, and branded voice interfaces.
A key tradeoff is that adding Krisp SDK processing can increase CPU utilization and memory pressure in the host app, especially when multiple concurrent streams are active. It also requires careful handling of audio device routing and sample rate matching inside the host application to avoid clipping or drift. Krisp SDK fits best when an app must deliver consistent noise suppression across browsers, headsets, and recording devices.
- +SDK embedding enables noise suppression inside custom voice apps
- +Virtual audio routing supports consistent mic cleanup for live sessions
- +Automation hooks help standardize behavior across many calls
- +API-driven workflow supports integration into existing audio pipelines
- –Host app audio routing complexity can cause latency or level issues

OBS Studio is best known for real-time audio routing and per-source effects, which matters for live noise cancelling workflows around voice calls and streaming. It provides a virtual audio device, lets each input carry independent filtering, and supports third-party DSP via its plugin pipeline. Noise reduction quality depends on the selected filters and the user’s audio chain, not on an integrated, call-specific cancellation engine.
- +Per-source audio effects let different mic presets run simultaneously
- +Virtual audio device enables routing to multiple apps and calls
- +Plugin host supports additional denoise methods beyond built-in filters
- +Scene switching helps enforce consistent mic processing for broadcasts
- –No built-in, call-aware acoustic echo cancellation for conferencing inputs
- –Stable latency requires careful buffer and filter ordering tuning
- –CPU load rises quickly with multiple real-time audio effects
- –Live noise cancelling depends on external filter selection and setup
Best for: Fits when live operators need scene-based mic processing and flexible audio routing across streaming and PC voice apps.

How to Choose the Right live noise cancelling software
Live noise cancelling software filters microphone audio in real time so speech remains intelligible during calls, streaming, and operator monitoring. This guide covers SteelSeries Sonar, NVIDIA Broadcast, Krisp SDK, OBS Studio, Cedar DNS One, Sonnox Oxford DeNoiser, Bertom Denoiser Classic, Acon Digital DeNoise 3, Razer Synapse, and Google Meet.
Tool choice depends on routing model and where the audio processing executes. Sonar and NVIDIA Broadcast use virtual audio device outputs for PC apps, while Krisp SDK targets embedding noise suppression into custom voice capture flows.
Live noise cancelling software for real-time mic cleanup and call-ready audio routing
Live noise cancelling software performs frame-based microphone processing for interactive voice use cases like live conferencing and streaming, where algorithmic latency and routing accuracy determine usable output. Many tools run as a virtual audio device so conferencing apps and streaming capture read the processed mic instead of the raw input.
Some options also target call-aware behavior instead of generic denoising, like Google Meet handling echo control inside the meeting call pipeline and SteelSeries Sonar splitting the same mic across per-application processing destinations for calls, chat, and stream capture. For teams building custom voice products, Krisp SDK exposes programmable processing output that can be inserted into live voice capture and playback flows while keeping mic routing consistent across sessions.
Live noise cancelling decision criteria
Live noise cancelling tools succeed when audio processing stays frame-based and the processed signal routes into the correct virtual input for calls, streaming, or operator monitoring. The routing layer often determines whether denoising and echo control actually reach the target app instead of being applied to the wrong device.
The strongest options also expose configuration patterns that reduce trial-and-error, such as per-application virtual device routing in SteelSeries Sonar or session provisioning in Cedar DNS One. For custom voice products, programmable output from Krisp SDK determines whether processing can be embedded into live capture flows with consistent mic routing.
Per-application mic routing for mixed call and stream workflows
SteelSeries Sonar routes the same mic through different processing destinations for calls, chat, and stream capture using per-application virtual routing. OBS Studio provides scene-level input processing chains with a virtual audio device output but lacks call-aware acoustic echo cancellation for conferencing inputs.
GPU-accelerated denoising and echo reduction on a supported PC
NVIDIA Broadcast uses a GPU-accelerated virtual audio device to deliver live denoising plus echo reduction for supported NVIDIA PCs. SteelSeries Sonar focuses on routing and per-app processing destinations, so GPU dependence is not the same constraint as in NVIDIA Broadcast.
Programmable integration for custom voice capture and playback
Krisp SDK provides programmable processing output for embedding into live voice capture and playback flows with consistent mic cleanup for live sessions. OBS Studio achieves integration through scene configuration and a virtual audio device, which supports operators but not the same SDK embedding workflow.
Scene-level chains for operators managing multiple mic presets
OBS Studio applies per-source audio effects so different mic presets can run simultaneously and operators can swap scenes while keeping virtual device routing stable. Cedar DNS One targets repeatable live call noise reduction across multiple PCs with reusable virtual audio device session configuration rather than operator scene chains.
Provisioning repeatable routing across multiple PCs
Cedar DNS One uses virtual audio device session configuration designed for provisioning repeatable voice and stream routing. SteelSeries Sonar emphasizes per-application virtual routing, so it improves mixed-use workflows but not multi-PC provisioning patterns.
Speech-focused denoising in a VST pipeline for monitoring
Sonnox Oxford DeNoiser integrates as a VST plugin with speech-optimized frequency processing designed to preserve consonant detail. It does not provide microphone array beamforming or echo cancellation, so it differs from Sonar and NVIDIA Broadcast where echo handling is part of the live routing experience.
Call-scoped noise reduction without a system-wide virtual device
Google Meet applies meeting-scoped audio processing inside the call pipeline for echo control and noise reduction. It lacks a dedicated virtual noise-cancelling device for system-wide PC audio, so it does not replace PC-wide live noise cancelling tools.
How to choose live noise cancelling software for your setup
Start with the routing model that matches where the audio enters and leaves the processing chain. Tools like SteelSeries Sonar and NVIDIA Broadcast work best when apps can select a processed virtual input, while Google Meet only improves audio within its own meeting pipeline.
Then select the integration depth that matches the deployment shape. Krisp SDK fits custom voice apps that need programmable processing output, while OBS Studio fits operators who need scene-level chains and flexible routing to multiple apps.
Match the processing endpoint to your app selection model
If conferencing apps and streaming capture apps must choose the cleaned mic, select a tool that provides virtual audio device outputs like SteelSeries Sonar, NVIDIA Broadcast, or Cedar DNS One. If audio quality must stay inside a single browser or mobile call pipeline, choose Google Meet where echo handling is built into the meeting call processing pipeline.
Pick the routing philosophy for mixed workflows
If one mic must feed separate processing destinations for calls, chat, and stream capture, choose SteelSeries Sonar because it sends the same mic through per-application processing destinations. If an operator needs scene-level mic chains with multiple presets, choose OBS Studio because per-source audio effects run inside scene configurations with a virtual audio device output.
Choose GPU-accelerated live processing when the PC supports it
If the target PC has compatible NVIDIA hardware and low-latency live effects are required for conferencing and streaming, choose NVIDIA Broadcast because the denoising and echo reduction run through a GPU-accelerated virtual audio device. If the workflow depends on per-app mic routing instead of GPU acceleration, choose SteelSeries Sonar where processed routing is the core mechanism.
Use SDK embedding when the product must own the audio pipeline
If the live noise cancelling must be inserted inside custom voice apps with programmable processing output, choose Krisp SDK because it supports SDK embedding into live voice capture and playback flows. If the need is denoised monitoring and routing into standard apps without SDK-level embedding, choose OBS Studio or dedicated denoisers like Sonnox Oxford DeNoiser through a VST pipeline.
Plan for echo cancellation coverage based on your call model
If two-way call artifacts from conferencing inputs matter, prioritize tools with call-aware echo handling like Sonar and NVIDIA Broadcast. If the workflow only needs speech denoising for monitoring without conferencing echo control, Sonnox Oxford DeNoiser is a narrower fit because it does not provide microphone array beamforming or echo cancellation.
Optimize for repeatable multi-PC operations versus single-machine setup
If multiple operator PCs must run consistent routing configurations for live sessions, choose Cedar DNS One because it is built around reusable virtual audio device session configuration. If the priority is per-headset consistency inside a single brand ecosystem, choose Razer Synapse where processing profiles follow the Razer virtual audio device across applications.
Who live noise cancelling software is for
Live noise cancelling software fits teams that must keep speech intelligible under non-stationary noise like keyboard bursts, reverberant rooms, and background chatter while still meeting the tight routing requirements of live voice apps.
The best tool depends on whether the processing happens at the system audio routing layer, inside a call pipeline, or inside a custom voice product using an SDK.
Streamers and call-heavy operators using multiple apps at once
SteelSeries Sonar fits mixed call and streaming workflows because it routes a single mic through per-application processed destinations. OBS Studio fits operators who need scene-based mic presets and flexible routing across streaming and PC voice apps.
Conferencing teams standardizing audio quality across many operator PCs
Cedar DNS One supports repeatable live call noise reduction through reusable virtual audio device session configuration. NVIDIA Broadcast fits teams with supported NVIDIA hardware that need strong local denoising plus echo reduction in real time.
Voice app teams building custom capture and playback features
Krisp SDK supports embedding noise suppression into custom voice apps so processed output can feed directly into live voice capture and playback flows. Google Meet fits teams that only need audio quality inside Meet sessions rather than PC-wide virtual device processing.
Creators who want denoised monitoring through a standard plugin chain
Sonnox Oxford DeNoiser is built as a VST plugin with speech-optimized frequency processing aimed at intelligibility during real-time monitoring. Bertom Denoiser Classic targets direct live mic output routing for calls and streaming but offers less integration depth for call platforms that need native media hooks.
Razer headset users who want consistent mic cleanup inside Synapse profiles
Razer Synapse keeps mic processing consistent across apps using device-bound profiles tied to the Razer virtual audio device. It is limited by headset compatibility and it does not offer the same SDK embedding depth as Krisp SDK.
Common live noise cancelling mistakes
Most failures come from selecting the processed device incorrectly or configuring chains that double-process the same microphone. Routing mistakes show up as latency, level mismatch, and inconsistent denoising behavior between apps.
Other mistakes come from expecting call-aware echo cancellation from tools that focus on speech denoising or from assuming plugin pipelines replace call pipeline echo control.
Selecting the wrong input device in the target app so the noise cancelling chain never receives microphone audio
SteelSeries Sonar, NVIDIA Broadcast, and Cedar DNS One require the app to select their processed virtual audio device output. If the app keeps using the raw mic, no denoising or echo reduction benefits apply.
Double processing the microphone by running a denoiser in both the system routing layer and the app chain
Cedar DNS One warns that careful audio routing is needed to avoid double processing when virtual devices are configured. If OBS Studio runs an effect chain and a system tool also processes the same virtual input, the combined chain can increase distortion or latency.
Assuming VST denoisers provide conferencing echo cancellation
Sonnox Oxford DeNoiser focuses on speech-optimized frequency processing in a VST pipeline and does not provide microphone array beamforming or echo cancellation. For call two-way artifacts, choose SteelSeries Sonar or NVIDIA Broadcast where echo handling is part of the live capture experience.
Underestimating the GPU and routing constraints when using NVIDIA Broadcast on unsupported hardware
NVIDIA Broadcast delivers effect quality through a GPU-accelerated virtual audio device, and effect quality drops when GPU requirements are not met. Routed-device selection must also be handled carefully so live apps use the processed virtual input.
Expecting system-wide noise cancelling from a call-only product
Google Meet applies echo control and noise reduction inside the meeting call pipeline and it does not provide a dedicated virtual noise-cancelling device for system-wide PC audio. Switching from Meet to desktop voice apps can remove the benefits unless a system-level virtual device is used.
