Frequently Asked Questions

How many tracks can I mix at once?

You can load up to 16 audio tracks simultaneously. Each track gets its own volume fader, pan knob, and full effects chain (EQ, reverb, compressor, filters).

What audio formats are supported?

The mixer accepts any format your browser can decode: MP3, WAV, FLAC, OGG, AAC, M4A, OPUS, and more. For export you can choose between WAV, MP3, FLAC, OGG, M4A, and OPUS with selectable bitrate.

What does the A/B bypass button do?

A/B bypass temporarily disables all effects on every track, letting you compare the dry mix with the processed version. This helps you evaluate whether your EQ, reverb, and compression settings actually improve the mix.

Can I save my project and continue later?

Yes. Click "Save Project" to download a .json file with all your settings — volumes, pans, effects, automation. Note that audio files are not included in the project file, so keep your original audio files.

What is the spectrum analyzer and vectorscope?

The spectrum analyzer shows the frequency distribution of your master output in real time — useful for spotting problematic buildups. The vectorscope displays the stereo field, helping you identify mono compatibility issues and ensure proper stereo width.
