Embodiment Construction
[0023] 1-8 and the various embodiments described in this disclosure are for illustration purposes only, and they should not be considered as limitations on the scope of the invention. Those skilled in the art will recognize that the various embodiments described herein may be modified, but such modifications fall within the scope of the invention.
[0024] As used herein, the phrase "perceptual audio coder" refers to an audio compression scheme that exploits the perceptual properties of human hearing. Various embodiments include techniques for configuring quantization noise below a masking threshold to render such noise imperceptible to the human ear. Such processing can be quite computationally intensive, in particular due to the psychoacoustic analysis and the bit allocation-quantization process. Techniques disclosed herein include methods to simplify the psychoacoustic modeling process by adaptively reusing computed masking thresholds based on signal characteristics. Also...
