Explanation of terms
DSD (Direct-Stream Digital)
One of the audio data recording methods, it is the signal aspect used to
store audio signals on a super audio CD, and is Δ-Σ modulated digital
audio. It is configured of an array of single bit values at a 2.8 MHz
sampling rate.
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at
regular intervals and expressing the height of the wave at each reading in
digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling
frequency”. The larger the value, the closer the reproduced sound is to the
original.
Linear PCM
This is an uncompressed PCM (Pulse Code Modulation) signal. This is the
same system used for CD audio but uses 192 kHz, 96 kHz, and 48 kHz
sampling frequencies on Blu-ray Disc or DVD and provides higher
resolution than CD.
