Topic: Analog audio mixer controllable via MAX/MSP (Read 1 time) previous topic - next topic


I'm wondering if the following would be possible using Arduino, and if so, what hardware would be required:

Analog audio mixer controllable via 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

--ideally these sends would have gain control or passive attenuation. Simple on/off would be OK too.

-- alternatively one-channel active or passive gain controls or on/off gates would work.

The purpose is to automate with Max a 'no input' analog feedback systems using guitar effects pedals.

Any pointers much appreciated!


Thanks for your reply! I found the following chips that look useful-- just wondering what Arduino hardware would be necessary for the project:

3 X 3in/2out

mic preamp


Just use the SPI library to talk to this one, very simple connection.
3-Wire SPI/QSPI/MICROWIRE-Compatible (MAX4549)

The second one, looks like you need a logic signal to switch between the two inputs.
Can be arduiono driven directly, or the output of a register that the ardiuno writes to.
