aqua-ear: audio perception tool (spectrogram, onsets, envelope, detectors, compare)
Python (numpy, scipy, matplotlib, soundfile). Onsets at 1 ms on a full-band and a >2 kHz channel; double hit, click/step/DC, clipping/true peak, overlapping tails, abrupt end detectors with stated assumptions; compare mode. True peak and BS.1770 loudness ported from aqua-feel/metrics.js (cross-checked against it in a test). 25 synthetic-fixture tests, each detector with a near-miss.
