MP3 Joiner - Version 1.0 MP3 Joiner features: Join unlimited .mp3 files into one. Lossless joining - .mp3 files are not decoded and re-encoded, but joined directly. No codecs required. ID3 tag data is removed from your .mp3 files to maximise compatibility with players. Super fast joining - MP3 Joiner understands the .mp3 file format without decoders/third party libraries. Low memory usage - only a small part of each .mp3 is loaded into memory in one go. Sort your .mp3 files alphabetically (A-Z). Change the order of your .mp3 files individually.
