maybe someone has an idea how to solve the following problem (I am using the ADAU1446):
- I have two audio inputs, "A" and "B", which are routed to an index selectable multiplexer
- the output of the multiplexer shall be input "A" if no signal on input "B" can be detected
- as soon as there's any signal detected on input "B", the output of the multiplexer shall switch to input "B".
so far so good - now the difficult issue:
- the multiplexer output shall remain input "B" for at least 2 - 5 seconds after the last signal on input "B" has been detected.
Any idea how to realize that? Anyone who can provide the schematic for that will make my day .-)
Thanks in advance
