ABSTRACT:
A method of adjusting an externally supplied audio signal as part of internally generated music data using a computing system is disclosed. At least one music generation algorithm is provided, which consists of at least one music rule associated with a set of acceptable pitch values. The music generation algorithm generates music data. An audio signal is received with at least one pitch characteristic. One or more portions of the audio signal is analyzed to discern the pitch characteristic. A determination is made whether the pitch characteristic is musically compatible with the set of acceptable pitch values. In the event that the pitch characteristic is not musically compatible with the set of acceptable pitch values, the portion of the audio signal is pitch adjusted to generate a pitch-corrected audio signal. The music data and the pitch-corrected audio signal is provided to a digital signal processing resource. The digital signal processing resource may be a hardware digital signal processor. The audio signal may be received from a microphone. User input may be received, and the user input may modify the music data corresponding to one or a plurality of instruments, audio samples or microphone input.
