RECORD SELECTOR
w
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.
