About:
Mp3wrap is a command-line utility that concatenates multiple MP3 files into a single, large MP3 file without the need for re-encoding. It achieves this by simply stitching the MP3 frames together, which makes the process extremely fast and preserves the original audio quality. The tool also writes ID3v1 tags to the resulting file, ensuring basic metadata is maintained.

Key Features:

Lossless concatenation without re-encoding
Extremely fast processing speed
Preserves and writes ID3v1 tags
Command-line interface for scripting and automation

Use Cases:

Combining multiple MP3 tracks from an album into a single file for continuous playback.
Merging segmented podcast episodes into one archive file.
Creating a single audiobook file from multiple chapter files.

Alternatives:

ffmpeg – A much more comprehensive multimedia framework that can also concatenate MP3s, but is heavier and more complex.
sox – A powerful command-line audio processing toolkit that can merge files, but requires more setup for simple concatenation.
