Is there a relationship between the frequency, bit rate and sound quality of an MP3? Part 7
Fifth, the compression method, there are vbr-old, vbr-new and two others in the software, but only the first two are easy to use.
Comparing old and new vbr encoding methods, I found that the assumption is that in terms of sound quality, it’s still the old one. Delicate, but the compression speed of the old encoding is very slow, almost equal to 5 or 6 times that of the new encoding method. The production of a song is almost the same. in 3-4 minutes, which is very difficult to use, and the file size is also 10% larger, so it is recommended to use vbr-new for everyone, which is more convenient and easy to use.
In short, we can say that there is an intimate relationship between the sampling rate and the bit rate to directly impact the quality of the audio, especially in formats such as mp3.
We have already said, in other articles, that an mp3 -which is a compression method that discards information- at high sampling rates (48 thousand 0 44100 samples) and a bitrate of 256, is almost impossible to distinguish, for most of them. people, from the original audio without any compression.
