Adjust your result

Set start and end times, then trim silence. Try a −48 dBFS silence threshold, −1 dBFS target peak, and a short 2 ms edge fade.

A useful tip

A threshold closer to zero trims more quiet audio. Listen to the result and lower it if the sound’s tail is cut off.

Choose a file above, then adjust these settings.

Exports 16-bit PCM WAV at the browser-decoded sample rate. This is peak normalization, not loudness mastering.

Next: prepare your files, then download them below.

WHAT YOU’LL GET
