Abstract:
A test system is configured to perform testing and calibration on a sound processing system by generating a test sound signal and measuring the outputs of the sound processing system in response to the test sound signal. The test system includes precision measurement instrumentation for measuring amplitudes and phases of signals generated by the sound processing system. The test system transmits configuration signals to the sound processing system to programmatically adjust one or more programmable gains and delays of the sound processing system.
