Mp3Doctor PRO is the ideal tool for optimize your mp3 files if you need to use a mp3 player, a memory stick,any portable device or to burn a mp3 CD or DVD. It analyzes each file and makes dynamic adjustments to achieve an even volume level across all songs, while at the same time preventing portions of a song from becoming inaudible as a result. Besides, the normalization is not carried out on the whole file with a single amplification value; this value is recalculated by each milisecond and practically modified for each note in the music. You can optimize the quality (not only the volume level) by using the equalize function and also can trim your files. Version 1.01.31 improves normalization feature and fixed some bugs.
What's new in this version:
Version 1.0.4 improves normalization feature and fixed some bugs.
When the process works, it does work well and the output MP3 is normalized optimally
* Fails on some MP3s and must be re-run against those that fail until it succeeds * With Replay-Gain enabled, output MP3 is missing tags (must re-tag these MP3s with other software) * Support email - no reply or assistance * Purchases are non-refundable, no matter what (free demo download works on the few it permits you to try, but when presented with over 1,000 MP3s in the batch, experienced failures and software freeze-ups)
If you've got time to babysit the batch of MP3s being "normalized", the software will eventually complete the task at hand. But, if you hope to "normalize" a large amount of MP3s in batch mode and just let things run to completion ... you may experience the same issues I've seen and have to stop & restart the process over and over and over again.
