Hi, I actually need something similar to this myself because I have some 
serious DSP processing enabled which causes delays to the audio signal

However, I was going to implement this simply in the audio routines by 
changing the audio timestamp which is returned (forget the call name).  
Just change this to be forwards or backwards by the required amount and 
we should achieve the desired result with very little code.

I would recommend that we try this before putting in the filters method?
