Abstract:
An audio processing system ( 100 ) accepts an audio bitstream having one of a plurality of predefined audio frame rates. The system comprises a front-end component ( 110 ), which receives a variable number of quantized spectral components, corresponding to one audio frame in any of the predefined audio frame rates, and performs an inverse quantization according to predetermined, frequency-dependent quantization levels. The front-end component may be agnostic of the audio frame rate. The audio processing system further comprises a frequency-domain processing stage ( 120 ) and a sample rate converter ( 130 ), which provide a reconstructed audio signal sampled at a target sampling frequency independent of the audio frame rate. By its frame-rate adaptability, the system can be configured to operate frame-synchronously in parallel with a video processing system that accepts plural video frame rates.

Claim (Index 1):
An audio processing system configured to accept an audio bitstream segmented into audio frames carrying audio data, the audio processing system comprising:\n a front-end component receiving the audio frames at a first audio frame rate; a processor adapted to output a first time-domain representation of an intermediate signal using a first mode; an analysis filterbank for receiving the time-domain representation of the intermediate signal and outputting a second frequency-domain representation of the intermediate signal; at least one processing component for receiving said second frequency-domain representation of the intermediate signal and outputting a frequency-domain representation of a processed audio signal; a synthesis filterbank for receiving the frequency-domain representation of the processed audio signal and outputting a time-domain representation of the processed audio signal; and a sample rate converter for receiving said time-domain representation of the processed audio signal and outputting a reconstructed audio signal sampled at the target sampling frequency, wherein the audio processing system is configured to accept an audio bitstream having any one of at least two different predefined audio frame rates and in that the front-end component has variable maximal frame length and is operable in a mode of the different modes that is selected in response to a current frame rate of the audio bitstream.
