I'm interested in making an inexpensive version of this
https://empac.rpi.edu/program/research/wave-field-synthesis
I saw an article written by Robert Keim which uses PWM and a low pass filter for audio in place of a DAC.
I would like to create an audio device that is recognized by a computer running MAX MSP and SPAT (see link) that will output as many channels of audio as I can. So computer to device - dac - amp - speakers. I also, eventually want to be able to put little modular speakers anywhere in a room and have directional control over those speakers rotate and tilt.
I have the typical budget of some who wants to experiement at home.
