20 / 78 page  WM9712L Production Data w PD, Rev 4.6, November 2011 20 RECORD SELECTOR The record selector determines which input signals are routed into the audio ADC. The left and right channels can be selected independently. This is useful for recording a phone call: one channel can be used for the RX signal and the other for the TX signal, so that both sides of the conversation are digitized.
