Digital audio? How do they do that?

It is not an easy task to transform audio waves into bits, but this can be done using various techniques. In the video from above we will learn about Bit Depth and Sample Frequency, two important aspects of digital audio.

Basically the Bit Depth is recording the volume of the sound and splitting it into tiny pieces. You’d like to have at least 24bit or 36bit depths so that you can listen to even the faintest sound. A Bit depth of 24 bit simply splits the audio volume into 16,7 million pieces.

Also, you’d need to have a Sample Frequency of at least 44.1Khz in order to generate all the possible sounds the human ear can listen to. The sample frequency splits the audio waves in small pieces. For a 22KHz wave you would need a 44.1KHz sample frequency.

The best way to enjoy the riches of audio is by using vinyl disks as they create a mirror wave pattern of the sound and they are able to replicate the original sound in the best way possible.

Digital audio, on the other hand needs to break down sound into pieces and then assign them some values. In this way some parts of the sound wave will be lost forever. This is why music creators say that digital audio, or the mp3, at least, is crap.

You can watch The Distorsion of Sound documentary. The video shows us how much creators hate the mp3:
