Application of Psychoacoustic Modeling in Audio Coding
https://www.vocal.com/audio/application-of-psychoacoustic-modeling-in-audio-coding/
Perceptual audio coding uses a relatively simple psychoacoustic model to perceptually quantize a given signal. An audio buffer is windowed and filtered using the analysis filter bank (AFB) into subbands. The bank type and the number of …

The proposed psychoacoustic model has direct application to digital perceptual audio coding as well as digital audio watermarking.For digital perceptual audio coding, greater extent of inaudible spectrum provided by the psychoacoustic model results more audio samples to be quantized to zero, leading to a decreased compression bit rate.

Improved Audio Coding Using a Psychoacoustic Model Based on a Cochlear Filter Bank Frank Baumgarte Abstract— Perceptual audio coders use an estimated masked threshold for the determination of the maximum permissible just-inaudible noise level introduced by quantization. This es-timate is derived from a psychoacoustic model mimicking the

©Yao Wang, 2004 EE3414: Audio Coding 18 Basic Steps in MPEG-1 Audio Coding 1. Use convolution filters to divide the audio signal into 32 frequency subbands --> sub-band filtering. 2. Determine amount of masking for each band based on its frequency (threshold-in-quiet), and the energy of its neighboring band in frequency and time
