>>>why would you need to resample/stretch them?

As mentioned earlier the two audio are identical but one will be ahead/delayed than other.

The user who is listening to it should not notice the switching, and this

switching happens when the quality of one audio is degraded compared to other.

For various reason, one audio receiving from network and

other thru air.

Yes delay estimation is required as the delay is not known upfront.

In addition to re-sampling stretching also required.

that turns it into a totally different problem. You originally said:

two identical audio inputs say A1 & A2.

why would you need to resample/stretch them?
