It is quick to judge whether the sound quality is good or bad from the data.<\/p>\n
However, there are several factors that make up sound quality.<\/p>\n
Therefore, in this article, I explained the sound quality in a rather broken way.<\/p>\n

Necessary environment to enjoy high resolution
\nHigh resolution sound source
\nHigh-resolution compatible headphones \/ earphones \/ speakers
\nHigh resolution compatible terminal

\nkHz (kilohertz)
\nkbps
\nLet’s briefly explain each unit.<\/p>\n
What is a bit?
\nbit is the number of quantization bits.<\/p>\n
Here, it is easy to understand if you think of it as “the resolution (fineness) of the sound itself”.<\/p>\n
The higher the value of this bit, the smaller and finer the sound can be reproduced.<\/p>\n
In other words, it is more faithful to the original sound.<\/p>\n
However, there is a disadvantage that the amount of data increases when the bit is large.<\/p>\n
What is kHz (kilohertz)?
\nkHz is the sampling frequency.<\/p>\n
It’s easy to understand if you think of it as “the number of data used in the expression of sound per second”.<\/p>\n
The higher this number, the greater the range that can be recorded.<\/p>\n
Also, kHz is one of the numbers often used to express headphone specifications.<\/p>\n
If you look at the specification table, you will often see numbers like “20Hz to 20kHz”.<\/p>\n
This indicates the range of supported ranges.<\/p>\n
The lower the number on the left, the better the bass can be heard, and the higher the number on the right, the greater the playback range.<\/p>\n
What is kbps?
\nkbps is the so-called bit rate.<\/p>\n
Also known as “bits per second” or “kilobits per second”.<\/p>\n
Unit that expresses how many kilobits of data can be transmitted per second.<\/p>\n
Kbps can be calculated using the following formula.<\/p>\n
kbps = bit x kHz x number of channels<\/p>\n
The number of channels is the number of speakers, for example, in stereo, it is “2”.<\/p>\n
In theory, the higher the number of processed bits per second, the higher the sound quality.<\/p>\n

High-resolution sound quality and CD comparison
\nLet’s compare CD and high resolution sound quality from a data point of view.<\/p>\n
little kHz kbps
\n16 bit CD 44.1-48 kHz 1,411.2 kbps
\nHigh resolution Exceeds 44.1 kHz \/ 16 bit
\nThose that exceed CD specifications are defined as high resolution.<\/p>\n
Specific examples are as follows.<\/p>\n
44.1 kHz \/ 16-bit: CD specifications
\n48 kHz \/ 16-bit: CD specifications
\n44.1 kHz \/ 24 bit: high resolution (the number of quantization bits is greater than the CD specification)
\n48 kHz \/ 24 bit: high resolution (the number of quantization bits is greater than the CD specification)
\n96 kHz \/ 16 bit: high resolution (sampling frequency is higher than CD specification)
\n96 kHz \/ 24-bit: high resolution (both higher than CD specs)
\n96 kHz \/ 12 bit: not high resolution (low number of quantization bits)
\n32 kHz \/ 24 bit: not high resolution (sample rate is low)<\/p>\n","protected":false},"excerpt":{"rendered":"
