Improve quality of mp3s
MP3 is often used as a compressed sound source when the capacity of uncompressed files like WAV and AIFF is large and inconvenient, but in fact, you know that depending on the settings like bit rate and sample rate, it can “write with fairly high sound quality”. mosquito?
This time about such MP3
Setting to export with high sound quality
Settings to export with good sound quality while saving space
Misleading Bitrate and Bit Depth Differences
I will also present on such things ^ – ^ No
1. What is MP3?
1.1 How do MP3s reduce their capacity?
2. About the MP3 export settings
2.1. The sample rate determines how many divisions per second
2.2. Bit rate (kbit) determines the amount of information per second
2.3 What values can be set when exporting MP3? What is the best export configuration?
3. What is the best setting to reduce capacity and export with good sound quality?
3.1. The sample rate is generally 44,100 Hz.
3.2 The bit rate is around 128 kbit, which is the limit between good and bad.
3.3. If you want to reduce the capacity and stick to the sound quality, it is better to select 128kbit ~ 192kbit and 44,100hz to export.
4. MP3 also has export settings. What are the settings for exporting with even slightly better sound quality? summary of

What is MP3?
MP3 is a compression technology (file format) that can reduce the capacity by 1/10 or more compared to the uncompressed compression method called “MPEG 1 Layer 3”.
It is also used when you want to save data capacity or when you collect a large number of songs in contests.
How do MP3s reduce their capacity?
~ How do MP3s reduce their capacity? ~
There are three reasons why MP3s can compress the capacity of a sound source 💡
Eliminate data in the “ultra high range (16 kHz or higher)” that is not as audible to humans at all frequencies.
It removes the data of small sounds that cannot be heard because they are erased by loud sounds for each frequency.
Humans cannot hear the small sound that plays immediately after the loud sound, so they cut it off.
