What is the sampling rate?
\nFor example, let’s say you say “Ah” for 1 second.<\/p>\n
When recording this “Ah” sound on a personal computer, the “Ah” sound is divided into tens of thousands per second, each divided into tens of thousands.<\/p>\n
“The height of this section was about this.”
\n“The length of this section was about this.”
\nRecord it as data like this.<\/p>\n
The personal computer continually reads each of this divided data and outputs it as a “voice” called “Ah”.<\/p>\n
At this time, “how many tens of thousands of sounds are collected per second” is called the “sample rate.” (Also called “sample rate”)<\/p>\n

The more divisions you make, the smoother the sound will be, and as a result, you will feel that the sound quality has improved!<\/p>\n
What is bit depth?
\nThe sample rate is “how many tens of thousands of sounds are collected per second”.<\/p>\n
“How much capacity is given to each divided data (sample)” is called “bit depth”.<\/p>\n

Also called “number of quantization bits”, “number of sample bits”, “bit offset”, and so on.<\/p>\n
For example, if the bit depth is “16 bits”, the amount of information is 2 to the 16th power (65536) for one sample.<\/p>\n
The higher the bit depth, the greater the expressiveness of the sound’s fineness and volume, and as a result, I feel like the sound quality has improved!<\/p>\n
By the way, the bit depth of most of the world’s sound sources is 16 bit.<\/p>\n
that’s why<\/p>\n
“Import music from CD!”
\n“Import music downloaded from the Internet!”
\nIn such cases, 16 bits is sufficient.<\/p>\n
On the other hand, if you say “What you recorded in your DAW comes out wav!”, It is better to have 16 bits or more.<\/p>\n
This is because, for example, when processing audio effects with audio editing software, sound deterioration can be reduced to zero by assigning an additional bit depth (for example, 32-bit). (Although 16 bit is fine for final output)<\/p>\n
What’s more,
\nnote that “bit depth” on this page has a different meaning than “bit depth” in video.<\/p>\n

What is a bit rate?
\nBit rate is the “amount of data per second”.<\/p>\n

The “sample rate” and “bit depth” presented above are<\/p>\n
Sample rate: how many tens of thousands of sounds are collected per second
\nBit depth: how much to give to each divided data
\nTherefore, the product of these two values \u200b\u200bis the “bit rate”.<\/p>\n","protected":false},"excerpt":{"rendered":"
