I'd like to build an audio matrix mixer in Arduino to control from MAX/MSP:
—ideally would be a matrix mixer (say 4 in and 4 out) where any combination of inputs could be sent to any combination of outputs
— these sends ideally would have gain control or passive attenuation. Simple on/off would be OK too.
— EQ filtering with parameters dynamically setable from MAX would be great too.
The purpose is to automate with Max/MSP a 'no input' feedback system.
The info I have so far:
3 X 3in/2out chiphttp://www.maxim-ic.com/datasheet/index.mvp/id/2046
>>Just use the SPI library to talk to this one, very simple connection.
3-Wire SPI/QSPI/MICROWIRE-Compatible (MAX4549)
I'm guessing something like the Arduino Duemilanove would be the bridge between MAX on my computer and the 4549 chip?
After looking at the data sheet for the MAX4549 (with very limited knowledge) it's unclear how audio is sent to/from the chip.
Any pointers would be appreciated!
