SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

butt (broadcast using this tool) is an easy to use, multi OS streaming tool. It supports ShoutCast and IceCast and runs on Linux, MacOS and Windows. The main purpose of butt is to stream live audio data from your computers Mic or Line input to an Shoutcast or Icecast server. Recording is also possible. It is NOT intended to be a server by itself or automatically stream a set of audio files.
This is the fast and Free (LGPL license) real time MPEG Audio Layer 1, 2 and 3 decoding library and console player. It uses floating point or integer math, along with several special optimizations (3DNow, SSE, ARM, ...) to make it most efficient.
utility to split mp3, ogg vorbis and FLAC files without decoding
mp3splt is a free utility to split mp3, ogg vorbis and FLAC files without decoding, selecting begin/end time; if file is an album, you can get splitpoints automatically from internet or a local cue, cddb file. It also splits Mp3Wrap and AlbumWrap archives. Supports splitting and trimming by silence detection. For mp3 files, both ID3v1 and ID3v2 are supported using original tags or user defined tags.
MAD is a high-quality fixed-point MPEG audio decoder with 24-bit output. The implementation is entirely new, based on the ISO/IEC standards, and performs especially well on systems without native floating-point support.
Audio and video streams generator
Audio toolkit for streaming, aiming at complex Internet radio and video systems. Our stream generator is highly extensible and flexible. Script based, it can be a fully automatic daemon streamer, but is also used for live shows with an user-friendly GUI.

An application that does scaling/deinterlacing/inverse telecine using a high powered PC and certain TV capture cards. Essentially, this software converts a PC into a good-quality line doubler/scaler/upconverter machine!
Mpxplay is a commander-style console audio player for DOS and Win32 operating systems. MMC is a GUI version of Mpxplay for Windows 7 with FFmpeg audio&video playing and translucent windows. x265vfw is a H265/HEVC video encoder/decoder codec for Windows, based on x264vfw and x265 library, usefull with VirtualDub.
Streamripper records shoutcast-compatible streams. For shoutcast style streams it finds the "meta data" or track separation data, and uses that as a marker for where the track should be separated.
TiMidity++ is an open source MIDI to WAVE converter and player.
Turn your Linux box into a complete audio and video production environment. This is the developer resource for all things related to the system.
Lossless compressor for multichannel 8,16 and 24 bits audio data, with the ability of password data protection. Being 'lossless' means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original.
