Two basic scripts exploiting these capabilities are shipped as well. . Replay Gain is a proposed standard designed to solve the very problem of varying volumes across audio files. Its specifications are available at http://replaygain.org/ .

The description sounds useful and relevant. It contains two scripts: 1. replaygain - read, calculate, and write Replay Gain for 1 or more files. works for several formats: ogg, flac, wavpack, mp4, mp3 2. collectiongain - does the same for an entire collection of music, just give it a path rather than filenames. Also, here's a list of packages in debian that mention replay gain somewhere in the package info: $ apt-cache search replay.?gain | awk -F' - ' '{printf "%-25s %s\n", $1, $2}' bs1770gain measure and adjust audio and video sound loudness crip terminal-based ripper/encoder/tagger tool groovebasin music player server with a web-based user interface libebur128-1 implementation of the EBU R128 loudness standard libebur128-dev implementation of the EBU R128 loudness standard (development files) libmpcdec-dev MusePack decoder libreplaygain-dev Calculate ReplayGain information libreplaygain1 Calculate ReplayGain information rhythmbox-plugins plugins for rhythmbox music player soundkonverter audio converter frontend for KDE vorbisgain add Replay Gain volume tags to Ogg Vorbis files bluemindo ergonomic and modern music player designed for audiophiles aacgain Lossless mp4 normalizer with statistical analysis libgrooveloudness4 loudness scanner for libgroove libgrooveloudness-dev loudness scanner sink for libgroove (development files) qmmp Feature-rich audio player with support of many formats python-rgain Replay Gain volume normalization Python tools PS: as is fairly common with python (and gem and ruby and node.js etc) programs, the web page for rgain gives instructions to first install the dependencies with apt-get (unneccessary but not actively harmful), and then cretinously tells you to run an installer script for rgain as root. Don't do that, it's extremely bad advice from programmers who don't care about the operating systems their code is running on, who see the OS as an obstacle to be worked around and trashed rather something to use and work with. Even without any malicious surprises in the installer script, that kind of advice breaks systems. Worse, it's an incredibly bad habit to get into especially for people who actually need instructions like that (they're exactly the people who should NEVER be encouraged to follow unsafe, insecure instructions). Ditto for instructions that do things like tell you pipe the output of wget or curl into a root sh or bash or whatever. Instead, just run 'apt-get install python-rgain'. All the dependencies will be resolved automatically by apt-get. That's its job. craig -- craig sanders <[email protected]> _______________________________________________ luv-main mailing list [email protected] https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
