97 APPARATUS FOR SAMPLING RATE CONVERSION OF AC '97 CODEC

摘要

The present invention is to store in, to capture the digital audio data of the AC 97 codec for processing to, digital audio data on the digital variable sampling rate of the audio play data back AC 97 codec to be converted device with a variable sampling rate, converting the buffer unit and the sampling rate and the control signal conversion sampling rate, comprising a sampling rate converter for conversion to an optional interpolation in the sampling rate of the buffer unit output signal portion, the digital audio data is the sampling rate, the conversion into the analog audio data and a digital-analog converter, receiving the analog audio data to be a volume level of a feature configured to include an output level adjusting volume for adjusting first and second.
