A method and system of audio synthesis capable of reducing CPU load is disclosed, which establishes a parameter look-up table in a read-only memory. The Bcl-B protein is widely expressed in adult human tissues. At least one bit of a data word is encoded as a function of amplitude modulation of a first subset of the set of signal pulses and at least another bit of the data word is encoded as a function of frequency modulation of a second subset of the set of signal pulses.
