The Java Media Framework (JMF) is an API for incorporating audio, video, and other time-based media into Java applications and applets. It is an optional package that extends the multimedia capabilities on the Java2 platform. The Blackdown JMF is a Performace Pack which includes native code in order to provide faster processing and tighter integration with Linux than the all-Java version.
DVTS (Digital Video Transport System) sends and receives DV data using the Internet. It consists of dvsend and dvrecv - dvsend receives DV data via IEEE1394, and sends it to dvrecv using IP, while dvrecv receives DV/RTP packets, and sends DV data using an IEEE1394 interface. Using DVTS, high quality realtime video meeting can be achieved. It consumes about 8-35 Mbps of network bandwidth. Supported platforms are FreeBSD4.x, MacOSX, and Linux.
xmcd2make is a set of Perl scripts which support users of the gramofile recording, track splitting, and signal processing package. It consists of 3 userland tools: findtracks.pl (a command line interface to gramofile track detection), signalproc.pl (a command line interface to gramofile track splitting and signal processing), and xmcd2make.pl (a script that takes an xmcd file of song names and track timing files and creates a makefile). When the makefile is run, it splits the tracks, performs gramofile signal processing, and encodes the resulting tracks to Ogg Vorbis format with the correct song names and good tags.
Manauton is a manual and autonomous sound recorder. In autonomous mode it can start and stop recording based on sound characteristics. When in manual mode, recording can be paused and un-paused manually. Using a series of buffers, the effect of negative latency can be accomplished, this effect cancels out the effect of the human latency associated with hearing a sound and interpreting it.
jMax is a visual programming environment for building interactive real-time musical and multimedia applications by allowing the user to interactively design dataflow circuits. The basic data types that can go through are integers, symbols, lists, etc. It is an event-driven system and has been used for MIDI processing. A second part of the system (DSP) allows a continuous signal to flow through a circuit, which is most useful for PCM sound (ie. microphone, sound files, etc.). The system is extensible by using shared libraries, you may add data processor types, data types, GUI elements, device types, and more. Data processors may also be designed as circuits and reused.
MP3do is an "all in one" bash script. It is useful for decoding and mastering audio files. It can decode a list of MP3 or Ogg Vorbis files to WAV or CD-R, auto-convert poor quality MP3s to 44100Hz stereo, check whether all files fit on a CD, normalize all WAV files (adjust the volume to a standard volume level), and burn a CD.
Maudio is a simple audio mirroring device (a sort of audio pipe). Unlike a filesystem pipe, maudio behaves as a hardware soundcard. In particular, after installation of the driver, you get two audio-like devices (usually /dev/dsp0 and /dev/dsp1) which are connected to each other. Everything sent to the first DSP will appear as sound data on the second DSP and vice versa.
