Sound spatialization using dsp.AudioRecorder and dsp.AudioPlayer

Hi, i have to drive an array of 32 loudspeakers sending to each loudspeaker the source signal (acquired with the object dsp.AudioRecorder or eventually with dsp.AudioFileReader) filtered with a specific spatial filter. I can't understand how to play each driving signal on the associated loudspeaker using the object dsp.AudioPlayer.

Someone can help me?

Thanks in advance.
