2-bit Quantization. 3-bit Quantization. 2-bit resolution quantizes the analog signal into four levels ( 2 2) 3-bit resolution quantizes into eight levels ( 2 3) The ATmega328 on the Arduino Uno, for example, has a 10-bit analog-to-digital (ADC) converter while the ESP32 has a 12-bit ADC.
Digital Audio Chapter Five: Quantization 2

dBFS (decibels relative to full scale (digital)) is a measurement of digital amplitude relative to the maximum sample value, and is therefore relative to sample size. 0 dBFS is set to the maximum value, and values below that are negative. For a 4-bit sample with 16 values, a steady-state signal with a maximum amplitudes between unsigned 0000 and 1111 would be considered to be at 0 …

Assume we play back the music so that the average level of the recording translates to a sound pressure of around 83 dB SPL, as is recommended because around that loudness range the audible frequency range is best (more on that later). That means that the quantization noise level is still 6 dB below the threshold of hearing in this case.

Coding of Audio. Quantization and transformation of data are collectively known as coding of the data. For audio, the μ - law technique for companding audio signals is usually combined with a simple algorithm that exploits the temporal redundancy present in audio signals.

If a sample lies between quantization levels, the maximum absolute quantization error $|e[n]|$ is half of the spacing between those levels. For the quantizer in Fig. 10, the maximum error between levels is 0.15 since the spacing is uniformly 0.3. Note, however, that if the sample overshoots the highest level or undershoots the lowest level by more than 0.15, the absolute quantization …

Audio-technicians might tell you: Quantization is the process of converting a continuous analog audio signal to a digital signal with discrete numerical values. Example: In a compact disc, an analog recording is converted to a digital signal sampled at 44,100Hz and quantized with 16-bits of data per sample.
