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.
The ALSA MIDI Filter application consists of a main script, named midifilter, and supporting Perl modules, configuration files, and documentation. It runs as an ALSA MIDI client that can receive input from a source (such as a MIDI keyboard connected to the computer), perform various filtering and other functionality based on the type and content of the MIDI input, and send the result to one or more other MIDI clients.
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.
m2vmp2cut is frame accurate (currently PAL) MPEG2 video (M2V file) with accompanied MP2 audio cutter. Frame accuracy is achieved by re-encoding video around cutpoints. Audio is cut from a separate MP2 file at positions that keep A/V sync as good as possible (maximum sync difference is around 10-15 milliseconds compared to the source).
GoldenPod is a command line podcast client. It allows you to easily manage and download podcasts from the command line. It can download podcasts from standard RSS(-like) feeds, or it can attempt to parse any other cleartext document (XML or HTML) for a list of audio files and download those. For users already using BashPodder, it can function as a more feature-rich drop-in replacement for it.
dmcat is a Digital Music CATalog program. Written in Perl, it recurses a physical directory, searching for digital music files, and builds a virtual catalog (out of symbolic links) in a sister directory. It currently only supports the MP3 format using ID3 tags. The following hierarchies are supported: Album, Artist, Artist_Album, Genre, Miscellaneous (catch-all), Title, and Year.
