Hi Nigel,

The delay will be estimated one time in the beginning and it remains constant. 
After that the audio which is ahead is buffered for that much.
When switching it has to align so that after switching to other audio, it 
should be glitch free and seamless meaning user should not notice the switching.

For eg: two same audio sources one a(t) and other a(t + T) where T is the delay 
between the two audio.

Suggestions of crossfading techniques, but I’m not convinced that solves the 
problem the OP posed:

"given [two] identical audio inputs...A1 is ahead of A2 by t sec, when switch 
from A1 to A2...it should be seamless”

If the definition of “seamless” is glitch-free, crossfading will solve it. But 
then why mention “identical" and “ahead”?

I think he’s talking about synchronization. And it’s unclear whether t is known.

I'm looking for an algorithm to blend two audio.  My requirement is
given tow identical audio inputs say A1 & A2.
A1 is ahead of A2 by t sec, when switch from A1 to A2
it should be seamless and vice versa.
