This process can also be carried out the other way around, converting MP3 with variable bitrate into CBR files (Constant bitrate files).
This kind of process comes in very handy when you are going to use a digital player that doesn't offer support for VBR files, as in the case of many of the players on the market, like for example the Pioneer: CDJ-200, CDJ-400...
You will be able to carry out batch conversions or modify the destination folder of the resulting files. In a few simple steps the process will be complete, which makes WinMP3Packer a lot easier to use.
To convert MP3 CBR to MP3 VBR format you have to have an application like WinMP3Packer. You'll be able to save space on your MP3 player in a very simple manner and with great results.
