Multi-track FAQ
Why is the mix longer/shorter than I expect?
Mix duration = longest input. Shorter tracks end early in the mix and silence fills the rest of the timeline.
Can I add effects per track?
Not yet. For finer control, render each track through the dedicated effects tools (EQ, compressor, etc.) first, then mix here.
What's the panning math?
Equal-power constant-power pan: full center = 0.707×L + 0.707×R; full left = 1×L + 0×R; full right = 0×L + 1×R. Sounds natural at any pan setting.
Is my file kept private?
Yes. We don't analyse or index your audio.
