Merge FLAC: Common Tasks

Combine FLAC album tracks into one file

Add the album tracks in order and join them back to back with no gap so the album plays as one continuous lossless FLAC - the closest you can get to a gapless album rip in one file.

Merge a live set or concert recording

Stitch the individual FLAC tracks of a live show or DJ set into one continuous lossless file, optionally with a short crossfade so applause and transitions flow naturally.

Join FLAC files without losing quality

FLAC is lossless compression, so merging FLAC files and exporting back to FLAC keeps the audio bit-for-bit identical to the sources. Keep the output on FLAC for an archival master.

Make a portable copy after merging

FLAC files are large. For a phone-friendly version of the same merge, use the full Audio Joiner and export as MP3 320 kbps or M4A.
