  • Frequency expansion for synthesizer
    Patent number: 7630780
    Abstract: A method is provided for generating synthetic audio signals with a synthesizer by generating a synthesizer output signal with a low sampling rate of the synthesizer. Because of the low sampling rate, missing high-frequency components of the synthesizer output signal are generated by adding a high-frequency signal. An amplitude-modulated high-frequency signal is preferred, and the amplitude-modulated signal S and synthesizer output signal are converted to a higher sampling rate.
    Type: Grant
