mkvtoolnix is a set of tools that allow users to display information about, extract streams from, merge several streams into, and split Matroska media files. Supported video stream types include streams from AVIs, Ogg/OGM, RealVideo, MP4 files, and MPEG program streams as well as verious elementary streams (h264/AVC, MPEG1/2, VC1, Dirac). Supported audio formats include AAC, (E)AC3, DTS/DTS-HD, FLAC, MP2, MP3, RealAudio, and Vorbis. Several subtitle formats are supported, including SRT, SSA, ASS, VobSub, and many others.
LiVES is a simple to use yet powerful video effects, editing, conversion, and playback system aimed at the digital video artist and VJ. It runs under Linux, BSD, Mac OS X/Darwin, IRIX, and openMosix. It is frame and sample accurate, can handle almost all types of video, and is fully extendable through plugins and the included plugin builder tool. It can also be controlled remotely using OSC.
Perl Audio Converter is a tool for converting multiple audio types from one format to another. It supports the following audio formats: 8SVX, 3G2, 3GP, AAC, AC3, ADTS, AIFF, AL, AMB, AMR, APE, AU, AVR, BONK, CAF, CDR, CVU, DAT, DTS, DVMS, F32, F64, FAP, FLA, FLAC, FSSD, GSRT, HCOM, IMA, IRCAM, LA, MAT, MAUD, MAT4, MAT5, M4A, MP2, MP3, MP4, MPC, MPP, NIST, OFF, OFR, OFS, OPUS, OGA, OGG, PAF, PRC, PVF, RA, RAM, RAW, RF64, SD2, SF, SHN, SMP, SND, SOU, SPX, SRN, TAK, TTA, TXW, VOC, VMS, VQF, W64, WAV, WMA, and WV. It can also extract audio from the following video extensions: RM, RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, OGV, QT, VCD, SVCD, M4V, NSV, NUV, PSP, SMK, VOB, FLV, WEBM and WMV. Parallel Processing, a CD ripping function with CDDB support, batch conversion, tag preservation for most supported formats, independent tag reading and writing, service menus for KDE Dolphin/Konqueror, a Gnome Nautilus script, and action scripts for Nemo/Thunar are also provided.
Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
MoreAmp is an audio player, transcoder, and CD ripper for Mac OS X, Mac OS 9, Windows, Unix, and Linux. It plays and creates ogg, flac, mp3, aac, m4a, mp4, wav, and aif files, and plays wma files. It features a 31-band equalizer, repeat loop, variable pitch/tempo, ram or ramdisk preload, and more.
Python Audio Tools is a collection of audio handling programs that work from the command line. These include programs for CD extraction, track conversion from one audio format to another, track renaming and retagging, track identification, CD burning from tracks, and more. It supports internationalized track filenames and metadata using Unicode. It works with high-definition, multi-channel audio as well as CD-quality. Track conversion uses multiple CPUs or CPU cores if available to greatly speed the transcoding process. Track metadata can be retrieved from MusicBrainz, FreeDB, or compatible servers. Audio formats supported are WAV, FLAC, WavPack, MP3, Ogg Vorbis, M4A, Apple Lossless, and more.
