The sampling frequency is the number of times per segundoque the audio signal is sampled and, of course, stored. A simple audio CD takes 44,100 samples per second, or 44.1 kHz.
What does this mean exactly? That an mp3 is composed of millions of frames, and every second is formed by an x amount of frames. The higher the audio sample rate is, the higher the frequency range offered. In other words, the higher quality. Their low will be lower, its peak will be higher.
The sampling rate can be considered as the frequency or amount of sonidoquee describe.La audiotipo cCalidad of CD has 44,100 of these measurements per second. That’s why we call 44.1 kilohertz (kHz).
That is the minimum acceptable level profgesional quality, a recording of 22050 by M second samples is not considered high quality or definition.
What that basically that’s what this is, how good is the definition of sound.
As for the bitrate is realativamnte facio to calculate and is as follows:
Bitrate = number of samples per second x DEPTH nin bit x number of channels.
A recording with a sampling of 44100 channels, bit depth of 16 and 2 channels, has 1411.2 kbits / s
All his is important for a archico calidadde, clear forever and ever we note that if we increase the number of samples per second, bit depth or number of channels, the audio file will take up more space on dissolution, will be larger.
Now, as the hundreds of MP3 archvivos we surely have different numbers, the quality is uneven and its volume level is also uneven, have the same volume our mp3s.
Because we frequently get questions about the main reason why there is so much difference in the volume of different mp3s. People ask if everything is a recording or mastering problem, and no. We do not say sometimes there are no differences in the mastering, what we say is that this is not the main reason for the inequality between the volume of an individual mp3s.
The reason, so we gave a somewhat technical explanation above, the difference was, for example, the bitrate to convert that file to mp3.
The volume is different as a result of others are also numbers.
The way of composing or even the volume of mp3s essimplemente not have everything at the same bitrate and samplerate. must make a much more complex analysis, including frequencies, in order to stabilize the volume to the volume level to achieve a similar volume between different mp3s.
Mp3Doctor offers this detailed analysis, performed 44 000 times per second to achieve fix the volume level of your mp3s.
