A clean fade separates a polished edit from a raw export. The Audio Fader adds fade-in and fade-out transitions with configurable duration and curve shape — so music intros ease in naturally, podcast endings trail out professionally, and background music beds never cut abruptly under a voice-over.
A 2-second fade never feels complete for music — 4–6 seconds gives the listener's brain time to process the ending. For a podcast music bed fading under a host sign-off, aim for 3–4 seconds timed to overlap with the last spoken word.
3–6 seconds is typical for song fade-outs in broadcast and streaming contexts. For podcast background music fading under a sign-off, 4–6 seconds timed to the last spoken word usually sounds most natural.
Yes. Set fade-in duration at the start and fade-out duration at the end and the tool applies both in a single pass — no need for separate export steps.
Linear fades are consistent in rate. Exponential fades start fast and trail off slowly. S-curve fades ease in and ease out, which feels the most natural for music transitions under voice-over.
