Interesting work - from their web site:
What is Monalisa-Audio Unit?
Monalisa-Audio Unit is a software component which allows you to
process audio using Apple Image Units by routing this audio through
any Audio Unit capable application. Monalisa-Audio Unit acts as a
plug-in host to mediate between Audio Units and Image Units, allowing
you to process your audio signal through any Image Unit. All
processing in Monalisa-Audio Unit is dependant on Image Units,
therefore by installing a new Image Unit you can in turn get a new
audio signal processing function.
Monalisa-Audio Unit is a world first for processing Audio Units via
the GPU (Graphics Processing Unit), utilising it's abundant
resources. Making it possible to use the GPU not only for 3d games
but also for audio signal processing. This presents new possibilities
for heavy realtime processing, which previously could not have been
handled by the CPU alone. From this point on, we are planning to
develop a "GPU Reverb" Image Unit which can perform audio reverb
processing using the GPU.
Monalisa-Audio Unit is a part of the application system Monalisa.
Monalisa can interconvert image and audio signal, while maintaining
it's structure. It enables real time processing for the process or
the end result of the conversion, using image/audio plug-ins.
Monalisa is under development and currently at alpha stage.
They have a video on the site that shows it in action...
