1. Fremgangsmåde til frekvenskompression af et audiosignal, som har en grundfrekvens og mindst en harmonisk (20, 30), ved - til rådighedstillelse af audiosignalet i flere frekvenskanaler (31,32) og - forskydning eller afbildning af den harmoniske (20, 30) af audiosignalet fra en første frekvenskanal (31) ud af de flere frekvenskanaler i en anden frekvenskanal (32) ud af de flere frekvenskanaler, kendetegnet ved - vurdering af en første frekvens (f3s), som ligeledes er harmonisk til grundfrekvensen, i den anden frekvenskanal (32), hvorved - den harmoniske (20, 30) forskydes eller afbildes på den vurderede første frekvens (f35), - hvorved den første frekvenskanal (31) forskydes fuldstændigt ind i den anden frekvenskanal (32), - hvorved en anden frekvens (f34), som er tilknyttet den forskudte harmoniske, vurderes, og den forskudte harmonisk (20, 30) forskydes videre til den første frekvens (f35) i den anden frekvenskanal (32), og - hvorved videreforskydningen til den første frekvens (f3s) sker ved amplitudemodulation.
