Detailed Description

Prepared, frame-quantized spectral delay built on SpectralFrameEngineT.

RT contract: prepare(), compile_table(), and publish_table() are control-thread operations. After prepare(), process(), reset(), and purge() allocate no memory, take no locks, perform no I/O, and throw no exceptions. Complete tables cross to the audio thread through a three-slot latest-value publication and are adopted only between spectral frames.
