DAP is a comprehensive audio sample editing and processing suite. It currently supports AIFF and AIFF-C audio files, 8 or 16 bit resolution, and 1, 2 or 4 channels of audio data. The package offers comprehensive editing, playback, and recording facilities including full time stretch resampling, manual data editing, and a reasonably complete DSP processing suite.
dsproxy emulates an OSS device that "virtualizes" itself so each UID that opens /dev/dsp gets its own private sound device. At this point, simultaneous reading of /dev/dsp by another process "samples" the data out of dsproxy. The tagged audio data and ioctls stream may be saved to disk locally as the example program does, retargeted over a network, pushed into an effects generator (3-D sound), etc. The virtualization feature is a stepping stone to adding sound to VNC on a per-desktop basis with each user appearing to have total control over /dev/dsp. Most OSS ioctls are implemented, so applications such as xmame and rvplayer7 may be retargeted through dsproxy.
Protux is being developed to be a complete Digital Media Production tool, or Digital Media Workstation. The focus is on GNU/Linux users, but it runs in any workstation with a Java >=1.5 VM installed, and even over the Web through a standard browser that supports Java. It aims to offer an integrated environment for audio, video, and MIDI production throught a innovative interface where the productivity is focused.
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.
PyMP3Cut is a Python command line tool designed to cut huge (> 100MB) MP3 files at high speed without requiring the extra disk space and processing time usually needed by visual audio editing tools, which convert the MP3 format to more easily manageable formats like WAV before doing anything. It reads and cuts simultaneously according to the autodetected MP3 frame rate and a timeline passed as a command line argument. It doesn't currently deal with Variable Bit Rate (VBR) MP3 files, though.
