About High-Resolution Audio format files
High-Resolution Audio, which is typically 96 kHz/24 bit or higher, is made by digitally
sampling an original analog audio source. The number of times at which sampling is
performed (in one-second increments) is called the sampling frequency, which is
expressed in hertz or “Hz”. Digitizing refers to the audio process where the sampled signal
is converted (or quantized) into binary digits, consisting of 1's and 0's, and expressed as
“bits”. The higher the number of bits, the closer the sample is to the original source. CDs
are standardized at 44.1 kHz/16 bit, but there is no single standard for High-Resolution
Audio.
An alternative way of digitizing an analog source is a method called DSD (Direct Stream
Digital) which captures sound information as a sequence of single bit values with an
extremely high sampling rate of either 2.8 MHz or 5.6 MHz. This is approximately 64 or
128 times the sampling rate of CD audio and is simply known as DSD 2.8 MHz or DSD 5.6
MHz. For some engineers, this is the closest a digital file sample can get to an original
analog source.
