What is the sample rate (sample rate)?

Differences in sound quality and how to check it! It also explains the settings to consider!

Adjusting the sample rate Sound quality

The sample rate is mentioned in the DAW and audio interface settings. How should I set it?
I googled “sample rate”, but I don’t understand all the difficult words …
The higher the sample rate, the better the sound quality?

For those people, here we explain in a way that is easy to understand even for beginners, from the meaning of the sample rate that always appears when starting DTM, the relationship with the sound quality, the confirmation method to the setting method. I would like it in a way.

Please refer to that.

1. What is the sampling frequency?
Adjusting the sample rate Sound quality
Sample rate is a frequency that indicates how accurately sound is captured. .

Sample rate, sample rate Also sometimes called sample rate in English.

The higher the number, the better it will be caught. .

Of course, if you want to import sound to your computer, you have to convert it to data. Capturing sound data is called sampling.

* Currently, sampling mainly refers to capturing existing sounds. (Using existing music, recording material, etc.)

Rate means rate or commission in Japanese.

In other words, sampling = sound data capture. Fee = fee, commission

Literally translated, “sample rate = sound data capture rate. It will be a commission.

In other words, the sample rate indicates how well the sound is captured.

For example, if the sampling frequency is 48 kHz, the data will be taken by dividing it into 48000 times per second.

The higher this value, the finer the sound will be sampled.

It may be easier to understand if you think of the version in which each pixel art block is a sound.

2. Does the sound quality change depending on the sampling frequency?

A common question is whether the sound quality changes based on frequency.

Naturally it changes.

However, beginners and those who do not have expensive equipment will not notice much even if it changes.

So I will show you how to check it!

What is bit?

bit is an abbreviation for binary digits.
16 bits and 24 bits in catalogs, etc. represent the number of binary digits * handled by computers, etc.

In digital audio, analog sound is converted to a digital signal,
but the number of bits determines how accurately the amplitude value is converted when it is converted to a binary number (quantization) after sampling.
In the case of 1 bit, only 1 or 0 can be judged, but in 8 bit (10001001), 2 raised to the eighth power, that is, 256 steps can be judged in detail.

Currently, the 16-bit mainstream has 65,536 steps and the 24-bit mainstream has 16,777,216 steps.
Now,
there is a part that does not match the actual waveform (analog waveform) and the quantized and sampled digital waveform. This is called quantization noise.
This noise is especially noticeable when the number of bits is small.

So simply increasing the F’s and the number of bits will improve the sound (closer to the original sound)
, but it will consume a lot of memory. Also, in the case of digital recording, it is
very important to manage the input level to bring out the high quality of the sound.
If the recording level is too low, you won’t be able to bring out its goodness.

It is important to configure it so that it is not clipping at the maximum level of the music to be recorded,
but try to increase the overall average level as much as possible to have a wider dynamic range
(recordable high and low level difference) than analog. Make the most of it and record with a good signal-to-noise (SN) ratio.

* The decimal numbers that we usually use are represented by a combination of 10 types of numbers from 0 to 9, but in
binary numbers, are represented by a combination of 0 and 1.

For example, in a 4-digit binary number,

Decimal number 0 1 2 3 Four ・ ・ ・ ・ 14 15
Binary number 0 1 Ten 11 100 ・ ・ ・ 1110 1111
You can express a number from 0 to 15 as.

(5) What is timing?

It is a state in which each device moves in harmony with each other at the same time in the system.

Digital devices use a reference signal called a word clock, and
Each device can be synchronized with a high precision that cannot be compared with analog devices.

For the configuration of each device, the device that supplies the reference word clock is set as the word clock master, and
all other devices are configured as
word clock slaves so that they can operate synchronously in response to the instruction of a unit set by this master increases.

The role of the word clock is similar to that of the conveyor belt used on factory assembly lines.

The digitized audio data is divided into small times, it is
they are transmitted to each device, they are processed and finally the DA converter returns them to an analog audio signal.
What happens if the speed of the conveyor belt changes along the way?
The data will be lost or the time will not match.

If there are devices in the system that are not synced
, problems such as loss of sound and noise mixing will occur due to the same cause.

With regard to synchronization, if each device is precisely configured and word clock transmission between each device is guaranteed,
can achieve high-performance and comfortable operation unique to digital technology.
