• Perceptual Audio Encoding is the encoding of audio signals, incorporating psychoacoustic knowledge of the auditory system, in order to reduce the amount of bits necessary to faithfully reproduce the signal. • MPEG-1 Layer III (aka mp3) • MPEG-2 Advanced Audio Coding (AAC)

The central objective of perceptual audio coders is different. Rather than favoring an output signal that faithfully preserves the input waveform, their error criterion favors an output signal that is useful to the human receiver. In short, to represent a signal with a minimum number of bits while producing an audio output at the desire fidelity.

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). The lossy perceptual coding algorithms
Perceptual Coding: How MP3 Compression Works
https://www.soundonsound.com/techniques/perceptual-coding-how-mp3-compression-works
Perceptual coding represents a move away from the idea that digital audio systems should accurately reproduce waveforms to the idea that they should be able to reproduce our perception of a waveform. The generic name for this system is Pulse Code Modulation (PCM), and it is used in all modern samplers, digital recorders and computer audio interfaces.

Perceptual bit allocation for low rate coding of narrowband audio by Hossein Najafzadeh, Peter Kabal , 2000 In this work we consider adaptive bit allocation for percep-tual coding of narrowband audio signals at low rates (down to 8 kb/s).
