General Stream Manipulation Platform 0.0.6

The General Stream Manipulation Platform (GSMP) aims to become for sound what The GIMP is for graphics.
Some years ago, there had been a lack of useable audio-software for Linux - especially for a good multitrack wave-editor - so we decided to write a gtk-- based one that is available under the terms of the GPL.
Now we focus on building a complete and open-source Virtual Studio environment for Linux:
GSMP Studio will feature both MIDI and DSP/Audio as well as beeing open for other kind of data.
It is intended to become a powerfull framework for the user to assemble his own "virtual studio" within the application from various components (like multitrack hd-recorder, midi-sequencer, synth and signalprocessors).
Other than most commercial applications of this kind, the hd-recorder and midi-sequencer will not be the neccessary components of this studio, and setups without them will be possible. For example GSMP can be used as a synthesizer or multi-effect-proccessor in live-setups.
Main features:
- Non-destructive editing: All action on the audio data can be made undone. So you can play around with the effects without modifying any bit of your original data file.
- Multi-threaded design: GSMP is multi-threaded. Especially the the wave-plots and the FXs are generated in a background thread and the UI keeps interactive!
- Internal sample-format: 24/8 bit fixed-point arithmetic is used to allow overflows with no acurrany loss.
- Internal sample-index: 64 bit indexes are used to allow live takes even at 96kHz DVD quality.
- Track count: The track count is not limitted. Also multi-track recording is supported, too. In fact we used GSMP-Editor to record 10 channels with the MIDIMAN Delta 1010 two month ago!!! (BTW: 2-8% CPU load on an Athlon 600Mhz ...)
- Realtime effect prehearing: Most effects can be pre-heared during playback!
- Supported import-formats: Currently MS-Wave, Ogg/Vorbis and MP3 (experimental!!!) are supported. Decompression is done on-the-fly!
- Supported export-formats: Currently only Wave is supported.
- Current effects: Fadings, graphical-eq, some IIR filters, compressor, noise-gate, de-click and reverb.
- The editor has multi-selections. This means you can select non-continous regions (that can be cutted or pasted) - like in The GIMP. You have to press the "Shift" or "Strg" key while moving the mouse for this.
- To enable the OSS plugin when ALSA is also compiled you have to add "--oss" on the command line. (The next release will contain a real dialog to change this ...)
- The two button in the lower-left corner of the main-window are "Follow Current Position" and "Follor IO Position" to let the view automatikally follow a marker ;-)
- When you load (import) a file the zoom is not changed. So you might not see a wave, because the zoom is still 1:1 -> simply zoom out a bit.
- To speed-up GSMP you should pipe all the debugging informations into the "null-device": "gsmp > /dev/null"
