In an apparatus configured to perform signal processing on audio data of a first sampling rate, methods disclosed herein comprise receiving audio data of a second sampling rate, the second sampling rate being higher than the first sampling rate. The methods comprise applying filtering to the audio data of the second sampling rate to thereby produce first filtered audio data and second filtered audio data, the first filtered audio data comprising mainly component frequencies which are audible to the human ear, the second filtered audio data comprising mainly components frequencies which are substantially inaudible to the human ear. The methods further comprise applying first signal processing to the first filtered audio data; and applying second signal processing to the second filtered audio data, the second signal processing having a lower computational complexity than the first signal processing. Corresponding apparatus and computer readable media are also disclosed herein.

Processing high-definition audio data

In some embodiments, a method for benchmarking an audio processing algorithm ('APA') while the APA is executed in a manner simulating expected real time execution by a deployed system. Other embodiments include a method including steps of determining a synthetic APA which corresponds to a counterpart APA (intended for real use by a first deployed system), and benchmarking the synthetic APA while it is executed in a manner simulating expected real time execution of the synthetic APA by a contemplated deployed system. Other aspects include a system or device configured to implement any embodiment of the inventive method, or including a memory which stores data indicative of at least one synthetic APA determined in accordance with, or a benchmark generated by, an embodiment of the inventive method or steps thereof, and a computer readable medium which stores code for implementing any embodiment of the inventive method or steps thereof.
