Set fade in duration

Enter fade-in seconds (e.g., 2 seconds for a 2-second fade in from silence).

Set fade out duration

Enter fade-out seconds (e.g., 3 seconds for a 3-second fade to silence at the end).

Choose curve type

Select Linear, Exponential (most natural) or Logarithmic curve.

What is a fade in / fade out in audio?

Fade in gradually increases volume from silence to full. Fade out gradually decreases volume from full to silence.

Which fade curve sounds most natural?

Exponential (squared) curves sound the most natural because human hearing responds logarithmically to loudness.

Can I add both fade in and fade out to the same file?

Yes — set both fade-in and fade-out durations and both will be applied in a single processing step.

What is the maximum fade duration?

You can set fade durations from 0 to 60 seconds — though they cannot exceed the total audio length.
