Frequently Asked Questions

Does changing speed affect the pitch?

By default, pitch is preserved when changing speed. You can optionally allow natural pitch change.

What speed range is available?

From 0.25x (4x slower) to 4x (4x faster) with fine-grained control.

What is the maximum file size?

There is no server limit since processing happens locally. Your device's memory is the only constraint — most handle files up to 100MB.
