In other words, MP3 can be said to be a sound source file that was originally created by removing only the sounds that are difficult for humans to hear and without modifying the other sounds.<\/p>\n

It is a commercially useful file format because it sounds very nice even if the capacity is small \ud83d\udca1<\/p>\n
About MP3 Export Settings<\/p>\n
When exporting MP3, the sound quality changes greatly depending on the bit rate (amount of data per second) and the sample rate (number of samples per second).<\/p>\n
The sample rate determines how many divisions per second
\n~ How many divisions per second? ~<\/p>\n
The sample rate determines how many divisions of information are handled per second.<\/p>\n
At 44,100Hz, which is common, one second of information is divided into 44,100 samples, and at 44,800Hz, it is divided into 48,000 samples \ud83d\udca1<\/p>\n
If you divide the sample into smaller samples, the information will be seamlessly connected, and if the information is approximate, it will be staggered.<\/p>\n
Bit rate (kbit) determines the amount of information per second
\n~ Amount of information per second ~<\/p>\n
On the other hand, the bit rate (bit) determines “the amount of information a sample has in one second”.<\/p>\n
soon,<\/p>\n
Bit rate = bit depth (1 sample information) x sample rate (number of samples per second)<\/p>\n
For example, the bit rate of a 16-bit 44,100 hz wav file is 705.6 kbit.<\/p>\n
Note that the bit rate is sometimes called “bps (bits per second)” because it is the number of bits per second \ud83d\udca1<\/p>\n
caution!<\/p>\n
* Bit depth is used in WAV export settings, etc. which is very similar, but the bit depth is the amount of information per sample. Be careful because it is confusing!<\/p>\n","protected":false},"excerpt":{"rendered":"
