A free browser-based multitrack recorder for capturing audio from multiple devices simultaneously. Record separate tracks for each input, mix them, and export — no software needed.

How to Record Multiple Microphones at Once

Connect your microphones

Plug in all the microphones you want to record from — USB mics, audio interfaces, or built-in mics all work.

Scan for devices

Click "Scan Devices" and allow microphone permissions. All detected audio input devices will appear as checkboxes.

Select devices and quality

Check the devices you want to record from and choose the audio quality (sample rate and bit depth).

Record simultaneously

Click "Start Recording" — all selected devices record at the same time, each into its own separate track with a live waveform display.

Download your tracks

Frequently Asked Questions

Can I really record from multiple microphones at the same time?

Yes! Modern browsers support opening multiple audio input devices simultaneously. Each device records into its own independent track that you can download separately.

What browsers support multi-track recording?

Chrome, Firefox, and Edge fully support simultaneous multi-device recording. Safari has limited support and may only allow one device at a time.

What audio formats can I export to?

You can export each track as WAV, MP3, OGG, or FLAC. The conversion is done locally using FFmpeg WebAssembly.

How long can I record?

There is no fixed time limit. Recording duration depends on your device memory. The recorder uses 1-second chunks to optimize memory usage for long sessions.

Can I use this for podcast recording with multiple guests?

Absolutely! Connect a separate microphone for each guest, and each person gets their own track. This makes editing and mixing much easier in post-production.
