Hi,

I am a electrical engineering student and am currently trying to implement an audio source localization system using a microphone array.

The microphone array consists of four mics, and the audio signal will be transmitted to a DSP board. Currently, the DSP board I have only has 2 inputs (1 mic, 1 line-in) and I was wondering how I could connect 4 mics to the board so that I could process them (Time delay of Arrival, etc)

Thank you

With only two channels three measurements will be required. Using channel 1 as the reference:

1-2
1-3
1-4
