sound:compute sharpness DIN 45692
Last update: 31.07.2026Version: 0.0.0
Description
Compute the overall sharpness and sharpness over time of a signal, where sharpness is defined in accordance with the DIN 45692 standard. The overall sharpness calculation uses the specific loudness computed according to the ISO 532-1 standard for stationary sounds as a basis. The sharpness over time calculation uses the specific loudness computed according to the ISO 532-1 standard for time-varying sounds as a basis.
