hi

Matt Black of Coldcut here.

as a step towards achieving multitrack audio visualisers, ie video synths which are controlled by multiple simultaneous audio inputs, i am interested in getting the following bit of software built, and think it could be made in PD. Am posting it here to see if anyone is interested. I can offer a fee to get this built.

This is the initial spec. I call it a Multitrack Analysis Module , MAM.

-MAM works with multi input ASIO soundcards eg RME fireface, and supports up to 16 audio ins.

-MAM performs SEPARATE fft /spectrum analysis on EACH AUDIO INPUT , say 16 frequency bands per input . delivers amplitude for each frequency band.

-outputs results of fft analysis as midi data. use cc numbers 1-16, with value 1-127 for the 16 frequency bands amplitudes. use midi channel 1-16 to distinguish the 16 audio inputs. Midi data can be routed to available midi interfaces/ports on the host machine, including virtual midi ports such as Maple, MidiYoke.

-optionally, output could be via OSC/ethernet which would get round possible MIDI data rate problems. (Do people think MIDI could handle this amount of data? it could be thinned)

-the MAM should be a self contained module , a stand alone patch that doesnt require a PD framework to run. As i dont know anything about PD , i dont know how it works, but you probably know what i mean.

-ideally, MAM would also be able to run with Ableton LIVE so that one can route the analysis data off to another machine to do the visuals, and still manipulate the audio on the machine with the audio ins in LIVE. this is not essential but i would like to know if people think it would be possible.

Hope this makes sense. I am looking for a good PD coder who is interested in working on a cutting edge project. A payment to build this initial module can be negotiated...not a huge one, but something. Interested parties can post here initially.

Thanks.
Matt Black

Thanks for your speedy reply. It reminded me tho that i have ommited a possibly crucial detail in the spec...i need MAM to be Windows .

Is this a problem?

Best
