SineFeature

Tracks the sinusoidal peaks of audio.

NoveltyFeature is closely linked with Sines and exposes the underlying sinusoidal peak tracking as a standalone audio descriptor. As a result it can be useful in understanding what assumptions its resynthesis sibling makes at a lower-level, or as a feature in and of itself.

For more information on how the tracking is achieved, see the chapter on interpolated peaks by Julius O. Smith.
