The color indicates the amplitude values that we capture. Because of this, when we take just 5 dimensions within a second, we will just have this misunderstanding in electronic recording with a gorgeous smooth audio waveform (we are only connected to pink dots): it is not exactly what it was before. And if you try to convert a recording to audio quality, you will probably be disgusted. How to proceed? Naturally, you will have to take “pictures” (samples) of the audio wave more often, that is, to list the voltage 2 times in one second: on the album we get an image, which is the same as before, but Far from it: to get as near as possible as possible and seems as fine as they seemed to exist, we got a whole lot more of analog signal samples (photos) Should be taken
If the rate is not large enough, we can leave the valleys and peaks of this wave, which will affect the quality. In other words, the frequency of sampling that is minimal destroys data of granularity and frequency range. So what is the speed of an MP3 file? How many “snapshots” are saved in this document every second? The first thing you need to see is an MP3 file which is currently a lossy compressed sound CD.

There is another important parameter that affects the standard of audio recording, known as bit thickness. To find out what this is, let us return to our wave drawing. Here we put pink directly at a certain interval across the line of this wave. We can set a point in other words, the sign is browsed by us accurately every fifth of the moment. But imagine that you cannot place a platform at altitude everywhere, this sign you did not browse. And you want to place a point right off the mark, on the tide, that is, maybe not. But read about it. Now we will remove everything and revel in electronic recording (the left side will be the first analog , And the same has happened as a result on the right side too) You don’t have to be a professional to realize that a copy does not correspond to the first.
And here we arrive at the notion of bit thickness or thickness of audio, which can be expressed in bits. Bit depth and detail show that we can capture the value of this voltage (or amplitude) at every specific moment. This is not enough to increase the reading frequency of the signal, you want to do it in detail. Imagine 3000 or 300 digits, although we do not have 3 marks on the axis. This will allow us to capture the value of this signal. Additionally, with a larger vibrant range.
This is a bit depth (bitness) that can also be known as a lively assortment of noise, because the higher the depth of this piece, the greater the difference between the loudest and quietest sound (in decibels) about the listing.
