Industrial acoustics
The methods Ezako applies to underwater recordings apply to the sound of machines and installations: events labeled on the spectrogram by specialists, then detected automatically and submitted to an analyst for validation.
On an acoustic recording
Spectral analysis
Mel, ERB, Bark, logarithmic and linear frequency scales; FFT size and overlap configurable per file; waveform synchronised with the visible range.
Listening
Variable playback speed beyond ×16; automatic gain control, equaliser and band-pass filtering; multichannel playback.
Annotation
Bounding boxes and contours on the spectrogram; hierarchical label taxonomy and custom fields per event; measurement and harmonic tools; batch editing; full undo history; keyboard-driven workflow.
Automatic detection
Real-time event detection on the spectrogram during playback, submitted to the analyst for validation.
