Detailed Description

Block of audio data, encoded in SpectMorph parametric format.

This represents a single analysis frame, usually containing sine waves in freqs and phases, and a noise envelope for everything that remained after subtracting the sine waves. The parameters original_fft and debug_samples are optional and are used for debugging only.

The documentation for this class was generated from the following files:
