Abstract

I ett beskrevet aspekt anvendes dynamisk forsterkningsmodifikasjon på et audiosignal i hvert fall delvis som reaksjon på hørehendelser og/eller graden av endring i signalegenskaper i tilknytning til nevnte hørehendelsesgrenser. I et annet aspekt deles et audiosignal inn i hørehendelser ved å sammenlikne forskjellen i spesifikk lydstyrke mellom suksessive tidsblokker av audiosignalet.
