Acoustic segmenter

Given one or more time series of the same source, find tones that are significantly above background noise. Multi-taper harmonic analysis is used to identify time-frequency pixels containing signal and machine vision techniques are used to turn adjacent pixels into contours. Output are bounding boxes consisting of start and stop times, and low and high frequencies. Designed for audio recordings of behaving animals but should generalize.
