MrsWatson is a commandline audio plugin host. It takes one or more plugins, sends an audio signal to them for processing, and saves the resulting output. Although the plugins think they are running in realtime, processing is actually done offline (this is not the same as the "offline" processing in VST terminology). This makes MrsWatson ideal for developing or debugging plugins, or processing audio on a server.
The Kowalski project aims to provide a data driven, lightweight cross platform audio solution. The target audience is developers of games and similar applications where real time audio plays an important role. The Kowalski engine, which is the runtime component, relies only on host-specific external libraries to pass the final output buffers to the audio hardware. All other processing is done in the engine code. Features include positional audio (distance attenuation, cone attenuation, Doppler shift, binaural panning), real time Ogg Vorbis decoding, a powerful mix bus system, and tools to build, validate, and view Kowalski data.
crtmpserver it is a high performance streaming server able to stream (live or recorded) in the following technologies: to and from Flash (RTMP, RTMPE, RTMPS, RTMPT, RTMPTE), to and from embedded devices (such as iPhone and Android), from surveillance cameras, and with IP-TV using MPEG-TS and RTSP/RTCP/RTP protocols. Also, crtmpserver can be used as a high performance rendesvous server. For example, it enables you to do audio/video conferencing, online gaming, online collaboration, and simple or complex chat applications.
pHash is an implementation of various perceptual hashing algorithms. A perceptual hash is a fingerprint of a multimedia file derived from various features from its content. Unlike cryptographic hash functions that rely on the avalanche effect of small changes in input leading to drastic changes in the output, perceptual hashes are "close" to one another if the features are similar. Potential applications include copyright protection, similarity searches for media files, or even digital forensics.
Algoscore is a graphical environment for algorithmic composition, where music is constructed directly in an interactive graphical score. The result is output to MIDI and CSound. Graphical objects are placed in a timeline and connected together. Some objects are fully dependent on user data, while some are generative and reacts on input from other objects. It is highly customizable and extensible with the Nasal scripting language. It has a non-realtime perspective where the composer can relate freely to time and construct the composition outside of time. This makes AlgoScore more like a traditional sequencer in this regard, but a graphical algorithmic sequencer with powerful and flexible scripting capabilities.
ebook2cw is a command line program that converts a plain text file (like an eBook) to Morse code (CW) MP3 or OGG files. Morse parameters like speed and tone frequency, and audio parameters such as bit rate, sample rate, and quality can be changed by command line switches. It automatically splits and numbers the output files by chapters.
Mylene is a command line MPEG audio player. It can play plain and system embedded MPEG audio streams and works for Linux OSS and ALSA emulated OSS and Mac OS X. The player can be used interactively by telling it to establish a UNIX or INET server on which commands can be received. It features sophisticated song selection filters, the ability to interpret programs written in a C-like programming language and user formatted text output among others. The seek-h262 MPEG decoder is required for audio and system MPEG decoding.
The Extended Module Player is a command-line mod player for Unix-like systems that plays over 90 mainstream and obscure module formats from Amiga, Atari, Acorn, Apple IIgs, C64, and PC, including Protracker (MOD), Scream Tracker 3 (S3M), Fast Tracker II (XM), and Impulse Tracker (IT) files.
JackMixDesk is based on JackMiniMix and is a general purpose mixer for the Jack Audio Connection Kit. It has an OSC-based control interface, and a configurable number of mono/stereo inputs and pre/post sends/outputs that can be controlled by sending it OSC messages. There is LASH support and an XML config file.
