<\/p>\nWhat is high resolution?<\/p>\n
<\/p>\n
Audio of “high resolution” and is an “high resolution” audio abbreviation, since the word “that” high (high) \u00b7 Resolution (resolution) of audio data refers to. A music CD (CD-DA) is the objective of comparison of what is a “higher” resolution.<\/p>\n

Therefore, in general, the data that has a greater size and are recorded in more detail than those that are recorded on a music CD are called high resolution audio. According to the definition of the Association of Information Technology and Electronics Industries of Japan (JEITA), it is linear PCM data with a resolution greater than 16 bits \/ 48 kHz. Normally, the music CDs are 16 bits \/ 44.1 kHz and the DVD-Video linear PCM Audio tracks are 16 bits \/ 48 kHz, making it easy to understand sensually if it considers it as data with higher resolution and density that the music data that he usually listens. I think.<\/p>\n
However, according to the definition of the Japan Audio Association, high-resolution audio is defined as linear PCM data and data in DSD format with a slightly higher resolution of 24 bits \/ 96 kHz or higher. By the way, the DSD format is a format developed by Sony for SACD (Super Audio CD), which became popular a long time ago. Then, in fact, SACD was of high resolution.<\/p>\n
Here, the resolution is two-dimensional, considering the linear PCM data, the sound stage (= dynamic range) and the tone step (= sampling frequency) when the “sound at a given moment” is cut. The matrix, expressed as a fine stage or determined by it. Mosaic of vertical and horizontal representations of two-dimensional imaging data in pixels to look like.<\/p>\n
For CD, 2 16 square (= 65536) Dynamic range representation of steps and 44.1k Hz (second 44100 times the sampling frequency of recording (sampling) reproducible to a height sound of approximately 20 kHz per) Therefore, these data with a resolution of 16 bits \/ 44.1 kHz.<\/p>\n
