How to merge audio files with different formats or settings

Add files and check their order

Choose Add files or Add folder. Review each entry’s duration and format. Select an entry and use Move up or Move down to set the sequence, then use Preview to check it.

This workflow places clips one after another. It is different from playing several tracks simultaneously in a multitrack mix.

Trim a clip before joining it

Select a file and choose Trim clip, or the row’s Trim action. Set the part you want to keep, then preview its beginning and end. Check the adjusted duration in the queue. Use Reset trim if you need the whole source again.

Choose a common output

Use Smart (recommended) or Studio merge when formats, sample rates or channel layouts differ. Choose an Output format accepted by your player, then review Sample rate and Channels.

The application can resample and re-encode to make a common result. That creates compatible audio rather than magically improving the originals. Lossless copy is more restrictive: matching technical properties and no processing that needs a new encode.

Set the boundary and save the result

Choose Direct join, Silent gap or Crossfade under Between clips. Use a direct join when you do not want to add an extra transition.

Set a separate output filename and click Merge audio. Check the duration and listen across each boundary. Cancel stops a job when you need to revise it; do not treat an unfinished output as the final recording.

See the audiobook guide for chapter order and CUE-sheet considerations, or join MP3 music for track transitions.
