MatLab Sound Sensors

[legoesl]

Hello,

Does anyone have experience in calibrating the sound sensors in Matlab? I have one on left and one on right, trying to tell the direction of a sound source. Under the same environment, the majority of data from the left is greater than from the right.

in Matlab i have
left = GetSound(SENSOR_3);
right =GetSound(SENSOR_2);

The delay in the collections may be a problem. Is there a way to collect data from two sound sensors at the same time in MatLab?

Thanks a lot !
