https://patents.google.com/patent/US20090271186A1/en
A technique is provided for limiting distortion of an audio signal being processed for playback by an audio device. In accordance with the technique, the audio signal is compressed to generate a compressed audio signal having a level that does not exceed a compression limit. The compressed audio signal is then soft clipped signal to generate a soft-clipped audio signal …
US9299333B2 - System for adaptive audio signal shaping …
https://patents.google.com/patent/US9299333B2/en
The shaping technique is applied to the far-end-speech signal or locally reproduced-audio signal, based on the near-end ambient noise characteristics that occur prior to the aforementioned far-end-speech or locally reproduced-audio signal's playback through the loudspeaker or earphone.

Audio Effects: The Beginner’s Guide to Shaping Your Sound. By Leticia Trandafir. ... Compression is the reduction of dynamic range—the difference between the loudest and quietest parts of an audio signal. When compression is applied, the quieter parts of the signal are boosted and the louder ones are attenuated.

What Is Spectral Shaping? - iZotope
https://www.izotope.com/en/learn/what-is-spectral-shaping.html
How does spectral shaping work? When compared to other frequency-dependent dynamics tools, like multiband compression, spectral shaping can offer far more resolution across the spectrum. By analyzing the signal across 32 Mel-spaced frequency bands, each band can be processed uniquely and without applying crossovers. You could imagine spectral …

5.3.7 The Mathematics of Dithering and Noise Shaping. Dithering is described in Section 5.1.2.5 as the addition of low-amplitude random noise to an audio signal as it is being quantized. The purpose of dithering is to prevent neighboring sample values from quantizing all to the same level, which can cause breaks or choppiness in the sound.
Sigma-Delta Conversion and Noise Shaping (part 2)
https://www.gammaelectronics.xyz/poda_6e_18b.html
The goal of noise-shaping systems is to dither the audio signal, then shape quantization noise to yield a less audible noise floor. These systems consider the fact that total noise power does not fully describe audibility of noise; perceived loudness also depends on spectral characteristics.
