Acoustic Landmark technology makes any difference between sounds measurable. It uses a modular framework, morphometrics, to capture the behavior of any time-varying feature. First, sound recordings are converted into images in time-frequency-amplitude space. In this representation, sounds of interest are visible as distinct shapes. Our proprietary algorithms convert these shapes into landmarks in time-frequency-amplitude space. The more complex the sound, the more landmarks it needs to describe it. By describing every sound in a data set with the same number of landmarks, we can make direct, quantitative comparisons between qualitatively different sounds.
