1 Function
Audio Analysis Transform (CAE-AAT):
| Receives | Audio Object |
| 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. |
| Produces | Audio Object (Transform) |
