Improve quality of mp3s Part 2
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.
It is a commercially useful file format because it sounds very nice even if the capacity is small 💡
About MP3 Export Settings
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).
The sample rate determines how many divisions per second
~ How many divisions per second? ~
The sample rate determines how many divisions of information are handled per second.
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 💡
If you divide the sample into smaller samples, the information will be seamlessly connected, and if the information is approximate, it will be staggered.
Bit rate (kbit) determines the amount of information per second
~ Amount of information per second ~
On the other hand, the bit rate (bit) determines “the amount of information a sample has in one second”.
soon,
Bit rate = bit depth (1 sample information) x sample rate (number of samples per second)
For example, the bit rate of a 16-bit 44,100 hz wav file is 705.6 kbit.
Note that the bit rate is sometimes called “bps (bits per second)” because it is the number of bits per second 💡
caution!
* 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!
