When the record starts, the driver turns on MICBIAS and the voltage is pulled up for an instant. If the receiver starts to capture the signal between the instant, there is an pop noise in the stream beginning. To avoid the pop noise, the driver makes a delay in the sequence. After MICBIAS powered up, the driver waits 300 ms for the voltage going down. Then turns on the ADC output, and sends signal to receiver. The pop noise can be erased.
