About the M4A format
M4A — MPEG-4 Audio
M4A is Apple's audio-only MPEG-4 container format, used by iTunes and Apple Music. It typically contains AAC audio and is functionally superior to MP3 at the same file size. It is the default export format from iTunes.
Common uses
- iTunes and Apple Music downloads
- iPhone voice memos
- Apple ecosystem audio files
- High-quality music purchases
About the BZ2 format
BZ2 — Bzip2 Compressed File
BZ2 is a single-file compression format using the bzip2 algorithm (Burrows-Wheeler transform + Huffman coding). It consistently achieves 10-15% better compression ratios than gzip for text and source code, making it preferred for bandwidth-sensitive distributions. Like gzip, it compresses only a single file — directories must be bundled with TAR first.
Common uses
- Compressing large text files and source code archives
- Linux package distribution (.deb source packages)
- Scientific data compression
- Bandwidth-sensitive file distribution
