Patent ID: 7442869

Claim:
A method suitable for church organ flue pipes' sound synthesis comprising: generating a first sinusoidal sequence ( 16 ), generating a second sinusoidal sequence ( 17 ) whose frequency is a multiple of said first sinusoidal sequence's frequency, generating a harmonic sequence ( 10 ) by means of processing said sinusoidal sequences, generating a periodic sequence (RATE) whose frequency is proportional to said harmonic sequence's frequency, generating a random sequence and processing said random sequence by means of a rate limiter ( 42 ) to obtain a limited rate sequence, and generating a sequence (NOISE) by means of processing said limited rate sequence, and processing said harmonic sequence ( 10 ) and said sequence (NOISE) by means of a closed loop of linear functional blocks to obtain an output sequence ( 13 ) which represents the sound of church organ flue pipes.
