Dithering audio before quantization - MATLAB & Simulink
https://www.mathworks.com/matlabcentral/answers/108931-dithering-audio-before-quantization
I have to write a matlab script that implements the audio dithering. The script receives as input a wav audio file (coded at 44.1kHz and 16 bit) and it has to be compressed at 2-3 bit! I have to show the difference between using a …

Audio Dither Goal: The purpose of this project is follow the paper of Lipshitz 2004 and to reproduce the results illustrating the value of dither for reducing harmonic distortion in a low level quantized audio signal. Step 1: Since Matlab signals are inherently digital we have to “cheat” a bit in these simulations.

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.

Dither is the solution to one of the fundamental problems in digital audio, so if we want to understand what it’s doing, we first need to understand the problem. In a nutshell, the problem is one of amplitude resolution, or how accurately we can measure the level of a signal using ones and zeros. When we try to measure an infinitely variable ...

Only dither when you render your audio to a lower bit-depth. Don’t dither before converting to MP3 or AAC. Always dither if you’re creating 16-bit files for a CD from a 24- or 32-bit mix. You don’t need to dither when going from 32-bit floating point to 24-bit (because 32-bit floating point doesn’t have a higher bit depth), but you do ...
