The delta-sigma (some say "sigma delta") converter digitizes the audio signal with a very low bit depth (generally 1-bit) but a very high sampling rate. The oversampling and subsequent digital processing reduce aliasing and other distortion or noise, potentially to a greater degree than LPCM encoding.
One-bit Delta Sigma Audio Encoding (DSD)
https://www.loc.gov/preservation/digital/formats/fdd/fdd000230.shtml
For audio, a delta-sigma converter digitizes the signal 1-bit deep with a very high sampling rate: 64 times the CD Audio sampling rate of 44.1 kHz, for a rate of 2.8224 MHz (1 bit times 64 times 44.1 kHz; rounded value 2.8 MHz). Advocates for this encoding state that the oversampling and subsequent digital processing reduces aliasing and other ...
How work sigma delta modulation in audio

Sigma delta modulator inside. 1. Delta-sigma modulator first integrates a multibit (input) signal (passes through an integrator [Low Frequency Pass Filter - LF]). 2. Output multilevel signal from integrator output divided to 1 and 0 (more zero / less zero). This is delta sigma modulated signal.

Why Delta Sigma for Audio : ADC Architectures • Delta Sigma : >16bit accuracy, closed loop Noise shaping, high Oversampling Ratio (OSR) --> high accuracy with a few bit, > 90dB with 1bit --> Narrow Signal Band Width (SBW), (1/OSR)*fos/2 --> relaxed Anti-Aliasing Filter (AAF) by high OSR Digital Decimation Filter
The Delta Sigma Story « Alef Audio

TMH Audio is the U.S. distributor for Delta Sigma, the Italian electronics manufacturer that is constructing the Pagani audio components. About a year ago, Ricketts traveled to the Delta Sigma factory outside Turin, Italy, to look for amplifiers with bandwidths sufficient to support the high-performance loudspeakers he distributes.

naturally inhabit the signal band of audio delta sigma modulators. Figure 12 shows the impact of too much white noise degrading the signal band, even with noise shaping. A. Capacitor Mismatch One of the early factors limiting delta sigma designers to single bit quantizers was the problem of capacitor mismatch.
