FAQ

What's a normal fade length?+

1–3 seconds for music, 0.2–0.5 seconds for speech and ringtones. Anything longer than the clip itself just becomes a constant volume change.

What curve does it use?+

Linear fade in amplitude. Most ears find this smooth enough; pro tools sometimes use logarithmic fades that perceptually match the ear better.
