We present techniques for processing MPEG-audio encoded signals during the decoding process, using efficient fixed-point arithmetic operations. A large signal-to-quantization-noise-ratio is achieved over a large range of input levels. By taking advantage of MPEG audio built-in properties, quantization distortion at the outputs of our systems is kept largely inaudible, even though only low-resolution fixed-point operations are used in the processing.
