MAD is a high-quality MPEG audio decoder. It currently supports MPEG-1 as well as the MPEG-2 extension to Lower Sampling Frequencies. All three audio layers (Layer I, Layer II, and Layer III a.k.a. MP3) are fully implemented. MAD does not yet support MPEG-2 multichannel audio (although it should be backward compatible with such streams) or AAC, nor does it support the so-called MPEG 2.5 format. This is ID3 tag library, which is part of the project. LICENSE: GPL2 or later

Sndio is a small audio and MIDI framework part of the OpenBSD project. It provides an lightweight audio & MIDI server and a fully documented user-space API to access either the server or directly the hardware in a uniform way. Sndio is designed to work for desktop applications, but pays special attention to synchronization mechanisms and reliability required by music applications. Reliability through simplicity are part of the project goals.

A real-time signal analysis tool and an offline time-frequency browser. It has a built in tone generation capability and it can play back audio files with a multitude of effects and filters. Designed for environmental analysis missions that range from modulation parameter measurements to searching for transient signals that go bump in the night, baudline combines fast digital signal processing, versatile high-speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics.

mp3lint is a tool to check collections of audio files for various problems. It is highly configurable, allowing you to specify your preferred format for filenames, minimum bitrate, tests to ignore, etc. Formats checked are currently mp3, ogg, wav, flac, au, and m3u playlists. mp3lint is implemented as separate tools (perl modules), each of which implements a set of tests. There are a total of 32 different tests.

This module returns a hash containing basic information about a FLAC file, a representation of the embedded cue sheet if one exists, as well as tag information contained in the FLAC file's Vorbis tags. There is no complete list of tag keys for Vorbis tags, as they can be defined by the user; the basic set of tags used for FLAC files include: * ALBUM * ARTIST * TITLE * DATE * GENRE * TRACKNUMBER * COMMENT

Squash is a C/Ncurses based music player. It supports mp3 and ogg through libraries (and planned flac support). Squash uses statistics to determine songs to play automatically. It garners this information through whether or not a song is skipped. Squash also avoids picking the same song twice. Thus Squash is like a radio station that plays the songs you like -- and you don't even have to call in requests!

Sexypsf is an XMMS plugin for playing .psf files. The PSF format brings the functionality of NSF, SID, SPC, and GBS to next- generation consoles. PSF utilizes the original music driver code from each game to replay sequenced music in a perfectly authentic, and size-efficient, way. The general idea is that a PSF file contains a zlib-compressed program which, if executed on the real console, would simply play the music.

dkftpbench is an FTP benchmark program inspired by SPECweb99. The result of the benchmark is a number-of-simultaneous-users rating; after running the benchmark properly, you have a good idea how many simultaneous dialup clients a server can support. The target bandwidth per client is set at 28.8 kilobits/second to model dialup users; this is important for servers on the real Internet, which often serve thousands of clients on only 10 MBits/sec of bandwidth.

This is lmbench-3.0-a9, a (sometimes controversial) system performance measurement tool. lmbench is a suite of simple, portable, ANSI/C microbenchmarks for UNIX/POSIX. In general, it measures two key features: latency and bandwidth. lmbench is intended to give system developers insight into basic costs of key operations. You can go to /usr/local/lib/lmbench and do one of the following: make results (to run the benchmarks) make rerun (to rerun the benchmarks) make see (to see how you did)

This is a network benchmark for DOS, OS/2 2.x, Windows NT/2000 and Unix. It measures the net throughput of a network via NetBIOS and/or TCP/IP protocols (Unix and DOS only support TCP/IP) using various different packet sizes. One instance has to run on one machine as a server process, another instance is used on another machine to perform the benchmark. When executed without arguments, the program will explain its usage.
