Non-standard Spectral Processing

These units generate and process non-standard signal data types, such as down-sampled time-domain control signals and audio signals, and their frequency-domain (spectral) representations. The data types (d-, w-) are self-defining, and the contents are not processable by any other Csound units. These unit generators are experimental, and subject to change between releases, they will also be joined by others later.

The opcodes for non-standard spectral processing are specaddm, specdiff, specdisp, specfilt, spechist, specptrk, specscal, specsum, and spectrum.
