...39;s not clear if preprocess is actually doing anything. If I turn AGC on, the sound level becomes almost inaudible. When I print the control parameters (the defaults), I get: DENOISE = 1 AGC = 0 AGC_LEVEL = 1174011904 AGC_INCREMENT = 12 AGC_DECREMENT = -40 AGC_MAX_GAIN = 30 VAD = 0 DEREVERB = 0 NOISE_SUPPRESS = -15 QUESTION number 1: Is there a guide to "tuning" the AGC? Is there a document that tells what they really mean and how to adjust them? QUESTION number 2: I see that VAD, DEREVERB, DENOISE, ... have values of 0 or 1. The documentation says that 1 means ON and 2 means OFF. Can so...
