Audio processing in multiple latency domains 

US 20150066175 A1

This patent is about audio processing in multiple latency domains. For complex audio effects that are to be generated computationally and can be split into two different latency domains namely low latency domain and high latency domain where these split signals are then individually processed. The individual outputs are then put together to get the desired output. 

For certain effects for which computation is separable into high and low latency functions, such dual signal network execution results in an overall signal latency of the low latency signal network and an overall efficiency of the high latency signal network which is desirable.

There are 15 claims that specify the total processing from taking the input, splitting them and then processing them individually. Examples are given for various signals that can be processed through this technique where its specified about which split signal can or should be processed through either DSP and/or a general purpose CPU.
