Frequently asked questions

How do I fade audio in and out?

Choose a recording and set each fade duration. Drag the waveform handles or enter exact seconds, preview the result, then export MP3 or WAV.

What is the difference between Smooth and Linear?

Linear changes the level at a steady rate. Smooth follows a curved rise and fall. Compare both to choose the transition that suits your recording.

Can I add only one fade?

Yes. Set either duration to zero to leave that edge unchanged. Fades keep the recording’s duration and affect both channels together.
