Audio sources do not always share a format. An introduction may be MP3, a voice track WAV and another segment FLAC. A decoder-based merge avoids manually converting each file first.

Merge audio files in different formats
Combine MP3, WAV, FLAC or OGG sources into one audio file and organize the operation as a multi-file pipeline.
Can MP3, WAV and FLAC be merged together?
Yes, when the merge engine can decode the inputs. Audio merger accepts several files and produces one result. File order matters because the tracks are concatenated sequentially.
WAV is a practical output when more processing follows. You can then use the audio converter to create MP3, FLAC, OGG, Opus or M4A. WAV to MP3 explains why final encoding is often best after the other transformations.
Trim unnecessary sections first with Audio trimmer. If levels differ strongly, consider volume adjustment.
A multi-file Workspace workflow
Import several audios → Merge → Adjust volume → Convert → DownloadThe Workspace moves the result between steps and Audio templates can provide a starting point. Manually normalizing every source format is not required when the merger already accepts them.
The main Audio guide places this workflow in the complete Audio family.
Key point
With mixed sources, avoid preparatory conversions that add no value. Merge, apply global transformations, then encode the final delivery format.
