## プロジェクトの歴史と使われ方
madplay is the command-line front end distributed with MAD, the MPEG Audio Decoder from Underbit Technologies. The official MAD page describes MAD as a high-quality MPEG audio decoder implementing MPEG-1, MPEG-2 lower sampling frequency extensions, the de facto MPEG 2.5 format, and all three MPEG audio layers including MP3.
### プロジェクトの歴史
Underbit distributes MAD as libmad, the madplay command-line front end, and the libid3tag ID3 tag library. The project emphasizes 24-bit PCM output, fixed-point integer computation, and a new implementation based on ISO/IEC standards rather than derivation from the ISO reference source.
### 採用の歴史
MAD and madplay became part of the classic Unix audio stack because fixed-point decoding was valuable on machines without fast floating-point units and because MP3 playback was a common package-manager use case. The official page notes third-party ports and packages for Debian, FreeBSD, and NetBSD, and lists many third-party applications using or planning to use MAD.
### 使われ方
madplay is used as a simple CLI audio player and decoder for MPEG audio streams, especially MP3 files. Package users typically install it when they want a small command-line player or a known-good libmad-based decoder for testing and scripting.
### パッケージ好きにとっての重要性
madplay is historically significant because it packages the front end to libmad, a GPL fixed-point MP3 decoder that showed up across many Unix media applications and ports. It is a small package, but it represents an older era of audio packaging where decoder accuracy, patent-era MP3 support, integer arithmetic, and command-line playback all mattered.
### タイムライン
- Official distribution: Underbit distributes MAD source via FTP and SourceForge mirror rather than an official HTTP source-control repository.
- Official package history: Underbit documents libmad, madplay, and libid3tag together as the MAD software distribution.
- Third-party packaging: Underbit notes third-party packages for Debian, FreeBSD, and NetBSD.
### Related projects
- madplay is related to libmad, libid3tag, mpg123, mpg321, LAME, GStreamer, MPlayer, VideoLAN Client, XMMS MAD plugins, and other Unix audio players and media frameworks listed on the official MAD applications page.
