Noise Cancellation for Browser Calls
Make crystal clear calls from Chrome, Firefox, or Safari. StartACall removes background noise in real time using browser side WebRTC and AI models so every conversation stays focused and professional.
How noise cancellation works in browser calls
StartACall combines browser level audio processing with cloud AI to remove background noise while preserving voice clarity. The result is faster setup and consistent audio on every call.
Client side filtering
The browser performs initial suppression using WebRTC built in constraints and a lightweight model to remove steady noises like fans and HVAC.
Cloud AI enhancement
Server side models analyze incoming audio and apply advanced noise reduction for impulsive sounds like typing, doors, and street noise while keeping speech natural.
Adaptive mode
Adaptive algorithms change sensitivity based on detected noise so calls remain stable in changing environments, such as moving from a street into a cafe.
Integrations
StartACall integrates WebRTC, Twilio PSTN bridging, and models from Deepgram and OpenAI to deliver end to end noise suppression for inbound and outbound calls. That means your agents and AI assistants sound clear whether they are remote or in noisy offices.
Why it matters
Clear calls improve customer experience, reduce repeat questions, and increase productivity. Noise suppression also reduces transcription errors when using real time AI copilots and voice agents.
Enable noise cancellation in three steps
Follow these steps to turn on noise suppression and get cleaner calls immediately.
Allow microphone access
When prompted by your browser, allow microphone access for startacall.com. Without permission noise cancellation cannot process your audio.
Open Call Settings
In the call interface, open Settings and toggle Noise Cancellation or AI Noise Suppression to on. Choose the desired sensitivity mode for your environment.
Test and optimize
Use the built in mic test, adjust the noise mode, and if needed switch to an external microphone or headset for best results.
Quick tips
- Place your microphone closer to your mouth and away from noisy sources.
- Use a headset for consistent audio pickup.
- Enable aggressive mode only when background noise is heavy, as it may reduce some ambient speech.
Frequently Asked Questions
Will noise cancellation affect my voice quality?
Noise cancellation improves clarity by removing background sounds. In very aggressive modes some room tone may be reduced, but speech remains intelligible. Choose balanced mode for natural voice.
Does StartACall use server side AI?
Yes. StartACall uses a combination of browser processing and server side AI models to provide robust noise suppression across different environments.
Can I use noise cancellation with AI copilot and voice agents?
Yes. Noise suppression improves transcription accuracy for AI copilots and allows autonomous voice agents to hear callers more clearly.
What if my browser does not support advanced audio APIs?
Most modern browsers support the required WebRTC features. If your browser lacks support you will still be able to call but with basic filtering only. Update to the latest browser for best results.
