Claims11
A computerized method for detecting a pitch of a musical signal comprising the steps of:
- receiving an electrical signal representative of the musical signal;
- identifying an active portion of the musical signal, the active portion comprising at least one of a noisy portion and a periodic portion;
- identifying the periodic portion of the active portion of the musical signal;
- determining a fundamental frequency of the periodic portion of the musical signal;
- and
- generating a pitch signal based on the fundamental frequency.
A computer readable medium having a computer executable program code stored thereon, the program code for determining the pitch of a musical signal, the program comprising;
- code for receiving an electrical representation of a musical signal;
- code for identifying an active portion of the musical signal;
- code for identifying a periodic portion of the musical signal;
- code for determining a fundamental frequency of the periodic portion of the musical signal;
- and
- code for generating a pitch signal based on the fundamental frequency.
A programmed computer for determining the pitch of a musical signal comprising:
- an input device for receiving an electrical representation of a musical signal;
- a storage device having a portion for storing computer executable program code;
- a processor for executing the computer program stored in the storage device wherein the processor is operative with the computer program code to:
- receive the electrical representation of the musical signal;
- identify an active portion of the musical signal;
- identify a periodic portion of the musical signal;
- and determine a fundamental frequency of the periodic portion of the musical signal;
- and
- an output device for outputting a pitch signal based on the fundamental frequency.
