Preliminary Technical Data

WM9713L

PTD, March 2004, Rev 2.2

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.
