About the AMR format
AMR — Adaptive Multi-Rate Audio
AMR is an audio codec optimized for speech compression, used in mobile phone voice calls and voice messages. It adapts its bitrate to match speech characteristics, achieving excellent voice quality at very low bitrates.
Common uses

About the TBZ2 format
TBZ2 — Bzip2-compressed TAR Archive
TBZ2 (also written as .tar.bz2) is a TAR archive compressed with the bzip2 algorithm. It achieves better compression ratios than gzip but at the cost of slower compression and decompression speeds. It is commonly used for distributing large source trees where download size matters more than speed.
Common uses
- Large Linux kernel and software source distributions
- Archiving large text-heavy data sets
- Release packages where download size is critical
- Scientific data archiving
