Audio Analysis Transform (CAE-AAT):

Receives Multichannel Audio (Transform Format)
Transforms Multichannel Audio into frequency bands via a Fast Fourier Transform (FFT). The following operations are carried out in discrete frequency bands. When such a configuration is used, a 50% overlap between subsequent audio blocks needs to be employed. The output is a data structure comprising complex valued audio samples in the frequency domain.
Determines Audio Objects’ Spatial Attitudes
Produces Audio Spatial Attitudes
