What does the quality of an mp3 depend on?
Factors influencing hearing quality
digital sound
We must consider that we are talking about digital sound.
The audio as we hear it from Daria is an analog audio. This means that it is a continuum, there are no partitions, cuts, chunks, etc.
On the other hand, digital audio is made up of thousands of points that make up a curve, but the curve is not continuous but is made up of a series of points.
Of course, the more points that curve has, the smoother the curve is and the more similar it is to the initial analog audio.
When the CD was developed, the conclusion was reached to make 44100 shots per second, so that the curve was smooth enough and could contain the sounds in the range that the human ear can perceive them.
Because there are sounds that are too high-pitched that we cannot hear them and also others that are so serious that we cannot perceive them.
It is even known that as the years go by, a person can perceive very high-pitched sounds less, unlike adolescents who perceive such high-pitched sounds better.
So the first factor to take into account will be to have 44,100 or 48,000 samples per second, in order to have a smooth curve, with high quality.
Recordings with less than that sample rate are not of high quality. Sample rate is called the number of samples taken per second to delineate the sound curve well.
So you take a naudio file and make sure it has a sample rate of at least 44100 or 48000 frames per second to know it’s CD quality.
There are higher samplerates, for example, 96000 but we will talk about it later.
Mp4Gain is a software that manages these parameters perfectly. If you really want high quality sound, Mp4Gain is the right tool for you.
