What is a high resolution sound source?
High-Resolution Audio is audio that has a higher sound quality than CDs. High resolution is an abbreviation for high resolution. High resolution means high resolution.
The sound source of a music CD ( CD-DA ) is recorded at 16-bit/44.1 kHz, while the sound source of 24-bit/96 kHz or higher is often referred to as a high-resolution sound source.
high resolution format
write Sampling frequency Bit depth Amount of information per second Difference in data volume on the CD
CD sound quality PCM 44.1KHz 16bit 705.6Kbps 1x
High resolution sound quality PCM 96KHz 24bit 2304Kbps 3.3 times
Hi-Res Sound Quality PCM 192KHz 24bit 4568Kbps 6.5 times
Sound quality DSC64 SACD 2.8224MHz 1 bit 2822.4Kbps 4.0 times
DSC128 5.6648MHz 1bit 5564.8Kbps 8.0 times
The sound gradation that can be expressed by the bit depth of PCM is as follows.
Sound gradation that can be expressed in 16 bits 2 16 gradation = 65,536 gradation
Sound gradation that can be expressed in 24 bits 2 24 gradation = 167,77,216 gradation
FLAC and ALAC lossless compression
ALAC of FLAC is a method of lossless compression. With the lossless compression method, the data before and after compression is exactly the same. Therefore, the sound quality does not deteriorate like MP3.
