摘要： The invention relates to a music synthesis system for synthesizing a corresponding digital music output according to commands from a music data file. The music data file comprises a plurality of music data units. Each music data unit records related information of the music. The music synthesis system comprises a wavetable, a memory, a music analyzer, a wavetable preprocessor, and a synthesizer. The wavetable pre-stores the digital sampling data. The memory has a predetermined memory capacity for storing data. The music analyzer receives the music data file, analyzes the music data units of the music data file, and generates a corresponding analysis result. The wavetable preprocessor selects the digital sampling data with relatively greater importance in the wavetable and stores the selected digital sampling data in the memory. The synthesizer selects the digital sampling data from the memory and synthesizes the digital music output.

摘要： The invention discloses a decoding apparatus for decoding an analog audio signal. The decoding apparatus includes an RF tuner, an analog to digital (A/D) converter, a digital down converter, and a programmable digital signal processor (DSP). The RF tuner is used for receiving the analog audio signal and for providing an analog sound intercarrier frequency (SIF) signal indicative thereof. The analog to digital (A/D) converter is used for sampling the analog SIF signal and for converting the signal into a digital SIF signal. The digital down converter is used for down converting the digital SIF signal to generate a baseband signal. The programmable digital signal processor (DSP) is used for demodulating the baseband signal according to a demodulation procedure of a predetermined standard and decoding the demodulated baseband signal to output an output signal in compliance with a decoding procedure of the predetermined standard.
