Merge Audio

Convert audio between MP3, WAV, OGG, AAC, FLAC and Opus with your own bitrate and sample rate.

Cut a start and an end time out of an audio file and keep only the part in between.

Speed audio up or slow it down between a quarter speed and four times, keeping the pitch if you want.

Raise or lower audio by a set number of decibels, or normalise it to a broadcast loudness.
