System and method for adjusting delay of an audio signal

A method of adjusting a time delay between a first audio signal and a second audio signal, the method comprising:

• generating the first audio signal from an input audio signal stored in a buffer as a first data stream;
• generating the second audio signal from the input audio signal stored in the buffer as a second data stream after an initial time delay;
• receiving the first data stream at a first sample rate converter at a first consumption rate and generating a first output data stream at an output sample rate;
• and
• receiving the second data stream at a second sample rate converter at a second consumption rate and generating a second output data stream at the output sample rate;
• and
• changing one of the first and second consumption rates so that the initial time delay between the first and second output data streams is adjusted over time to provide an adjusted time delay, wherein the first and second output data streams are used to simulate the input audio signal propagating through an environment by a first path associated with the first output data stream and a second path associated with the second output data stream.
