- Description
- DSD uses pulse-density modulation encoding - a technology to store audio signals on digital storage media which are used for the SACD. The signal is stored as delta-sigma modulated digital audio, a sequence of single-bit values at a sampling rate of 2.8224 MHz (64 times the CD audio sampling rate of 44.1 kHz, but only at 1⁄32768 of its 16-bit resolution). Noise shaping occurs by use of the 64-times oversampled signal to reduce noise and distortion caused by the inaccuracy of quantization of the audio signal to a single bit. Therefore, it is a topic of discussion whether it is possible to eliminate distortion in one-bit delta-sigma conversion.
- The XA file format, associated with Maxis, is used primarily for storing audio data in certain video games developed by Maxis, the video game company known for creating popular titles like SimCity and The Sims series. The XA format allows for efficient compression of audio data, enabling games to include a variety of sounds and music tracks without using an excessive amount of disk space. This format is specifically designed to be used within the game environment, facilitating seamless playback and integration of sound effects and music.
