perceptual audio encoders (e.g. quantization & quantization noise, sub-band coding & bit allocation, tone & noise masking thresholds, etc.) 2) Describe the methods of Experiment 1 and the results you obtained. Explain how the threshold results obtained relate to the masking thresholds used in perceptual audio encoding.

Fundamentals of Perceptual Audio Coding Craig Lewiston INTRODUCTION Conventional CD and digital audiotape (DAT) systems sample at 44.1 kHz using pulse code modulation1 (PCM) with a 16-bit sample resolution. This results in a data rate of 705.6 kbits per second (kb/s) for a monaural channel or 1.41 Mbits per second (Mb/s) for

Music 422 : Perceptual Audio Coding
https://ccrma.stanford.edu/courses/422/index.htm
We review the basic principles underlying all the core components of a perceptual audio codec and study the design choices applied in state-of-the-art audio coding schemes, e.g. AC-3 (aka Dolby Digital), Enhanced AC-3, AC-4; MPEG Layers I, II, and III (MP3); MPEG AAC; MPEG-H. In-class demonstrations will allow students to hear the quality of ...

Coding Params. Fig. 1. Generic Perceptual Audio Encoder The study of perceptual entropy (PE) suggests that transparent coding is possible in the neighborhood of 2 bits per sample [101] for most for high-fidelity audio sources (~88 kpbs given 44.1 kHz sampling).

Music 422 : Perceptual Audio Coding
https://ccrma.stanford.edu/courses/422-winter-2018/index.htm
Perceptual audio coders are currently used in many applications including Digital Radio and Television, Digital Sound on Film, and Multimedia/Internet Audio. In this course, the basic principles of perceptual audio coding will be reviewed. Current and future applications (e.g. AC-3, MPEG) will be presented.
What is Perceptual Coding? | Webopedia
https://www.webopedia.com/definitions/perceptual-coding/
In digital audio perceptual coding is a coding method used to reduce the amount of data needed to produce high-quality sound. Perceptual coding takes advantage of the human ear, screening out a certain amount of sound that is perceived as noise. In perceptual coding you reduce or eliminate the sounds that the ear would perceive as noise.
Perceptual Coding: How MP3 Compression Works
https://www.soundonsound.com/techniques/perceptual-coding-how-mp3-compression-works
Perceptual Coding. What makes MP3 encoding effective as a method of audio data compression is its deviation from the PCM model. As we have seen, in a PCM system the goal is to digitally reproduce the waveform of an incoming signal as accurately as is practically possible.
