3 Ways to Change Bitrate of MP3 Files Part 2
The second thing you want to read is that you should never convert to a lower bitrate. bitrate to a higher bitrate stream and I hope it sounds better. You cannot gain quality by increasing the bit rate. This is absolutely correct. If you try to convert the bitrate, you will actually lower the quality of the MP3 file.
If you want an MP3 with a higher bitrate than it currently has, you’ll need to go back to the source (CD, etc.) and extract the audio at full quality. You can then convert that file to a higher bitrate MP3 file.
The last thing you need to know is that converting between lossy formats is not recommended as you will still lose quality. However, it is possible to convert between formats losslessly while preserving quality.
On the other hand, many tests done even with recording engineers or professional musicians have shown that less than 1% of the population can distinguish between an mp3 with good bitrate (196 for example) and a samplerate of 44100 or more.
There is a sector of puritanism that defends tooth and nail the use of losless formats, because in theory they seem to be better, but the limitations and peculiarities of human hatred mean that a loosy file with a high bitrate and a high samplerate is enough for the human ear.
Mp4Gain is the most professional and polished program to help you in all these matters and you can achieve the highest sound quality with any format.
