How to make an mp3 sound great?
If you want to know how an mp3 works, this article is for you.
An mp3 stores information digitally. The music is captured 44100 times per second, each of these parts has a size of 16 or 24 bits. The usual is 16 bits.
The sound has a curved shape, what is sought is that each frame captures an instant of that curve or bell.
If 16 bits are used, we have a little more than 65 points that form a kind of grid where each point will be located to form the curvature. It is enough information to achieve a very good definition. In 24 buts we have several million possible points on the grid to place each point on the curve.
To understand the size of a file, the following formula will be useful:
frames*bits*channels= x bits per second
In a good quality mp3 we speak of 44100 multiplied by 16 bits multiplied by 2 channels (stereo) which gives us 1,411,200 bits per second, that is, 176,000 bytes per second.
If the song lasts an average of 3 minutes, each one will occupy 32 million bytes.
Using Mp3 that 32 million bit song can be compressed to about 3 million bits.
We will need to be able to transmit 16,666 per second to be able to transmit the 3 million bits of the total song.
We will see that the more information it contains, the more transmission capacity per second we will need.
Mp4Gain is the ideal program to get these mp3s that have a sound practically identical to a CD.
