Patent ID: 7512453

Claim:
An audio data synthesis system for sequentially processing a first predetermined number of audio data to synthesize a digital audio signal cumulatively, the system comprising: a first memory for storing a plurality of audio data; a first processor for generating an audio processing request for requesting to process a second predetermined number of audio data; an audio data processing unit for receiving the audio processing request; accessing the second predetermined number of audio data stored in the first memory; and according to a data processing formulae, calculating every two neighboring audio data of the second predetermined number of audio data to get a data processing value, and after calculating all the second predetermined number of audio data, then obtaining a third predetermined number of data processing values; a second memory for storing the third predetermined number of audio data; wherein when the audio data processing unit has finished processing the second predetermined number of audio data, the first processor continuously generates follow-up audio processing requests, until all the first predetermined number of audio data have been processed, then the first processor synthesizes the data processing values corresponding to the first predetermined number of audio data which is temporarily stored in the second memory, into a digital audio signal, and then outputs the signal.
