Audio Merger FAQs
Files, formats, pauses, and transitions.
No. Your audio files stay on your device. Merging and exporting happen in your browser. Website analytics do not include your audio files.
You can add MP3, WAV, M4A, OGG, FLAC, and AAC files when your browser can decode them. Export is available as MP3 or WAV.
Direct joins keep the pauses already in each included clip. A crossfade overlaps the end of one clip with the start of the next for the duration you choose.
At a join between two files, choose Add pause to insert extra silence or Crossfade to overlap them with a fade, then set the duration.
