“High resolution” basics. What is the difference between DSD, FLAC, MQA, etc.? Part 6
Review the basics of “high resolution”. What is the difference between DSD, FLAC, MQA, etc.?
There are several formats, even if it says “high resolution”. If the format changes, the amount of sound information and thus the sound quality will change, the file size will also change, and whether the playback device / software will support it or not, it will also change, so choose a format is important. We will explain the main formats incorporating common technologies and unique pieces.
There are several high-resolution formats, but …
What is the sampling frequency?
Most digital sound sources are “linear PCM”. This is data obtained by digitizing (sampling) the sound waveform (analog signal) in a canned cycle, and that cycle is called the “sample rate.” If sampling is done every 1/44100 of a second it will be “44.1 kHz”, if it is 1/96000 of a second it will be “96 kHz”, if it is 1/192000 of a second it will be “192kHz”. This means that the implementation cycle of is shorter and the amount of information is greater. In other words, if you look at this number, you can see “how finely the sound was measured with respect to time.”
What is the number of quantization bits?
Value that indicates the number of steps in which the amplitude of a signal is expressed when an analog signal is converted into a signal.
