AudioMulch is an interactive musician's environment. Bringing together the popular and the experimental, AudioMulch merges the worlds of mainstream electronica and electroacoustic sound composition to create a fluid sonic environment.

While many of the processes featured within AudioMulch are not new to computer music programs, it is the software's ability to carry out these traditionally "studio" or "non-real-time" signal processing techniques in real-time that emerges as its major asset. With AudioMulch, music that has for so long been limited to the pre & post-production practices of a studio can emerge in a new LIVE and interactive context.

Through the essentially unlimited (only by the power of the computer) combination of a network of synthesis and processing contraptions, AudioMulch allows the user to extend their current audio processing capabilities or create new music within their computer without additional expensive software or hardware systems.

AudioMulch 'Contraptions' (signal processing elements) include:

• Signal Generators: Test tone / noise, drum machine, bassline synthesizer, additive synthesizer, stored sample granulator, loop player, streaming sound file players and recorders (up to 24 channels), Shepard / Risset tone generator, arpeggiator.
• Effects: Reverb, flanger, phaser, delay line granulator, ring / amplitude modulation, stereo delays, dynamic stereo spatialiser, waveshaper / distortion, digital grunge inducer, pulsar comb filter, frequency shifter, 16 channel live sampling looper, live sampling "canon" looper.
• Filters: Parametric EQ, resonant comb filter bank, Shepard / Risset filter bank, granular filtering, resonant lowpass with pattern triggering and envelope following control.
• Mixers: Mono and stereo mixers and gain elements, crossfader, matrix with variable fade times.

AudioMulch supports VST audio effects plugins, allowing hundreds of free plugins and many commercial plugins to be used within the AudioMulch environment.

AudioMulch can be used to process and generate sound files or as a live performance instrument.

AudioMulch allows any processing parameter to be controlled via MIDI. It can synchronise to an external MIDI clock source or generate MIDI clocks which other devices can synchronise with. You can also synchronise copies of AudioMulch running on different computers using a wired or wireless network.

Up to 24 channels of real-time audio input and output can be generated and / or processed by AudioMulch when used in conjunction with a multi-channel soundcard.

For multi-channel and surround sound applications AudioMulch supports recording and playback of multi-channel sound-files, or multiple synchronised sound-files.
