WinMP3Packer 1.0.18 and MP3Packer 2.04

WinMP3Packer reduces the size of high bitrate CBR (constant-bit-rate) files and converts them to VBR (variable-bit-rate) files.

In high bit-rate CBR files, a lot of space is wasted, but this compact application enables you to store MP3s in the most efficient possible way.

With WinMP3Packer, CBR file size can be reduced by up to 10% without compromising on sound quality. The program eliminates all the padding it can from any MP3 file.

Results also depend on the used LAME version. After the task is completed, a pop up window informs you on how much size has been reduced from the MP3 file you have processed.

WinMP3Packer works the other way around, too; you can convert VBR files to larger CBR files in case your player doesn’t support VBR.

Other useful features of WinMP3Packer are writing valid LAME Xing header for efficient VBR seeking, applying a strong compression optimization option to compress files even more, multi-core support, being able to encode an entire directory of music files, and support for Unicode file names and paths.

The application also features 64-bit support, and precompiled Windows executable builds for 32 and 64 bit are available as well.

Nevertheless, WinMP3Packer comes with a limitation, too; it doesn’t support Free format MP3s and it cannot repack them.

WinMP3Packer is an up-to-date application whose latest version included various enhancements, like proper CBR/VBR type detection, and the possibility to add custom options to the mp3packer command line.

WinMP3Packer helps you save memory space due to its smart compression options. The software can reduce MP3 file size by 50%, if you select the VBR output type, and the difference in sound quality is almost unnoticeable.
