Create a subclass of AudioStreamX with a AudioStream (which takes the final output) as parameter and the number of seconds to be ignored in the constructor.
From this parameter you can calculate the number of bytes to be ignored (with the help of the number of channels, sample rate and bits_per_sample).
Implement the write() method which ignores the data until the calculated limit is reached and after the limit has been reached you can forward the write to the final output.

Then you can just add this new class into your output chain. This approach works also with encoded (e.g mp3) data.
