Systems and methods for creating, modifying, interacting with and playing musical compositions
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.
1. A method of adjusting an externally supplied audio signal as part of an internally generated music data using a computing system, comprised of:
providing at least one music generation algorithm comprised of at least one music rule associated with a set of acceptable pitch values, wherein the music generation algorithm generates music data;
receiving an audio signal with at least one pitch characteristic;
analyzing one or more portions of the audio signal to discern the pitch characteristic;
determining whether the pitch characteristic corresponds to the set of acceptable pitch values;
in the event that the pitch characteristic does not correspond to the set of acceptable pitch values, pitch-adjusting the portion of the audio signal to generate a pitch-corrected audio signal; and
providing the music data and the pitch-corrected audio signal to a digital signal processing resource.
2. The method of claim 1 , wherein the digital signal processing resource comprises a hardware digital signal processor.
3. The method of claim 1 , wherein the audio signal is received from a microphone.
4. The method of claim 1 , further comprising the step of receiving a user input wherein the user input modifies particular music data corresponding to one or a plurality of instruments, audio samples or microphone input.
5. The method of claim 1 , wherein the music data is stored for subsequent playback or played in real time as a live performance.
6. The method of claim 5 , wherein the music data has a size of 0.5 KB or less.
7. The method of claim 1 , wherein an animated visual display is presented while the music data is generated.
8. The method of claim 1 , wherein the music generation algorithm makes use of one or more seed values as inputs to a random number generation routine.
9. A method of adjusting an externally supplied audio signal as part of an internally generated music data using a computing system, comprising the steps of:
providing at least one music generation algorithm comprised of at least one music rule associated with a set of desired rhythmic parameters, wherein the music generation algorithm generates music data;
receiving an audio signal with at least one rhythmic characteristic;
analyzing one or more portions of the audio signal to discern the rhythmic characteristic;
determining whether the rhythmic characteristic corresponds to the set of desired rhythmic parameters;
in the event that the rhythmic characteristic does not correspond to the set of desired rhythmic parameters, time-adjusting the portion of the audio signal to generate a time-adjusted audio signal; and
providing the music data and the time-adjusted audio signal to a digital signal processing resource.
10. The method of claim 9 , wherein the digital signal processing resource comprises a hardware digital signal processor.
11. The method of claim 9 , wherein the audio signal is received from a microphone.
12. The method of claim 7 , further comprising the step of receiving a user input wherein the user input modifies particular music data corresponding to one or a plurality of instruments, audio samples or microphone input.
13. The method of claim 9 , wherein the music data is stored for subsequent playback or played in real time as a live performance.
14. The method of claim 13 , wherein the music data has a size of 0.5 KB or less.
15. The method of claim 9 , wherein an animated visual display is presented while the music data is generated.
16. The method of claim 9 , wherein the music generation algorithm makes use of one or more seed values as inputs to a random number generation routine.
