Route sound effects, music, and your microphone into any browser call
Audio Cable turns your Chrome browser into a real-time virtual microphone mixer.
It creates Audio Cable Virtual Mic, a selectable microphone input that works inside web-based communication tools such as Google Meet, Zoom, Discord, Microsoft Teams, Whereby, and other apps that use your browser microphone.
Once selected, the virtual mic sends a live mix of your real microphone and any audio clips you choose to play. You can trigger sound effects, intros, transitions, background ambience, music clips, pre-recorded speech, lesson audio, or any other local audio file directly into your call — without installing desktop software, drivers, or a separate virtual audio cable app.
It follows local-first and private rules. Your audio files stay in your browser storage. Audio processing happens locally using browser audio APIs. No cloud account is required.
How it works:
Audio Cable adds a virtual microphone option to websites that request microphone access. When a web app selects the virtual mic, Audio Cable provides a live mixed audio stream containing your selected physical microphone plus any audio assets currently playing.
From the web app’s perspective, it behaves like a normal microphone input.
What you can do with Audio Cable:
Create a virtual microphone in your browser. Select “Audio Cable Virtual Mic” in your web app’s microphone settings and use it like a normal microphone. Use it as a soundboard for calls and streams.
Mix your real microphone with audio assets. Speak through your physical mic while playing sounds into the same audio stream in real time. Trigger effects, jingles, intros, reactions, transitions, hold music, or ambient background audio. Loop selected sounds for continuous background music, ambience, or soundscapes.
Add your own audio files. Add MP3, WAV, OGG, and other browser-supported audio files to your personal library. Organize sounds with tags and categories. Name, tag, search, filter, and organize your audio assets in list or grid view.
Monitor what others hear. Enable local monitoring to hear the final mixed output in your headphones before or during a call.
Note:
Some apps, including video meeting platforms, may apply their own noise suppression or voice enhancement. These systems can sometimes reduce or filter music, effects, or other non-voice audio. For best results, disable noise suppression or background noise removal in the meeting app when you want non-voice sounds to pass through clearly.
Interesting product.
The thing I'd be careful with is that a long list of capabilities can make it harder to see the moment someone decides they need it.
That sounds like a small distinction, but it usually ends up affecting everything from positioning to conversion.
I wouldn't make that call casually in a thread.
Thank you for your positive opinion about our extension and for the good advice. I decided to narrow the capabilities list down to 4 main features of the app: a virtual microphone, mixing sounds, a sound library, and an output monitor.
Interesting.
Your reply actually made me think about the consequence of narrowing the feature set in a way I hadn't before.
It's not really about having four features instead of twenty. There's a second-order effect that can quietly shape how people evaluate the product from their very first interaction.
I don't think I can explain the reasoning properly in a thread without flattening it.
If you're open to it, what's the best email to reach you on?
