How to merge MP3 files

Open the first file, insert the next at the playhead, crossfade the join, then export one MP3.

“MP3 merge” sits in the same cluster as “mp3 trim” (~90k) and “cut mp3”. WaveSmith concatenates on the waveform with an optional crossfade so the join does not click.

Insert File drops another clip at the playhead. Paste can crossfade. Concatenate tabs when the story is serial — an interview in three recordings, not three websites.

“Merge MP3” sits with “mp3 trim” (~90.5k/mo). Concatenate on the waveform, listen to the join, then Convert/Export one file. Do not glue files in an archive tool that cannot hear the click.

How to do it in WaveSmith

1. Open the first MP3 so the waveform paints.

   

2. File → Insert File at the playhead (or paste with crossfade).

   

3. Listen to the join, then Convert/Export one MP3 for the whole piece.
