Abstract:
1. A computer-based method for modulating audio effects of speakers in a sound system, the method comprising: selecting a speaker from the speakers, and turning on the selected speaker; playing an audio file stored in a storage device to generate an audio signal, and tracking a playing start time of the audio file; outputting the audio signal via the selected speaker; recording and storing the audio signal as a new audio file via a microphone, and tracking a recording start time; determining a time difference between the playing start time and the recording start time; determining a pitch of the new audio file; repeating from the selecting step to the computing step, until all time differences and pitches for all of the speakers have been determined; and modulating the time difference and the pitch for each of the speakers to a desired time difference and a desired audio pitch.
