Optimize and convert your audio and music files to smaller MP3 files (up to 5-20%) lossless! Program attempts to save space by storing frame data in the smallest possible frame. Usually MP3s are already stored in the most efficient way possible. However, for high-bitrate CBR files (like preset insane) there can be a lot of wasted space. Full compatible with original MP3 format. It uses program MP3packer 2.04. Batch processing of files (drag-n-drop). Reduce the size of your MP3 files in one click without quality loss! Program optimizes your file to new one with «_optimized» name ending (source file will remain intact).

In “Good” mode program try choose the minimum frame size to fit the data and will also minimize the data size. This is completely lossless, and is equivalent to decompressing a ZIP file and recompressing with a more aggressive setting. In “Best” mode it attempts to minimize the data by doing a brute-force search for the optimal parameters, so it takes longer than it would normally.
– Reduce the size of high bitrate CBR files, turning them into VBR files.
– Writes valid LAME Xing header for proper VBR seeking.
– Full compatible with original MP3 format.
– Supported format: MP3.
– Option “Strip metadata (ID3v2 tags etc)”.
– Option “Copy time creation from source file”.
– You can set «Run in background (without console output)» or uncheck it for manual process control.
Run only 1 active instance of the program!
Current file has its own status in the list: «running», «done» and «saved space».
1. Number of optimized files (total and current session).
2. Files in the queue (quantity).
3. Saved disk space (Mb) total and for each file in the list.
(You need to save files «res\size.txt» and «res\numbers.txt» before updating, if you want to save the overall statistics («Total»)).
You can specify the path to the file «mp3packer.exe» manually in a separate form.
