Has anyone seen such a software as a real time audio frequency multiplier ..
Ie pc soundcard based , audio in / audio out .. not frequency shifted but multiplied in frequency by a factor ..ie x 4 :- 200 hz in = 800 Hz out 400 hz in = 1600 Hz out 800 hz in = 3200 Hz out The event time is not changed, so its not like a tape speed changer where the duration is also modified .. amplitude liniartity would be 'nice' but not 100 % important can it be done ? has it ? music production ? Tnx- G ..
