Projects / Normalize


Normalize is a tool for adjusting the volume of audio files to a standard volume level. This is useful for things like creating mix CDs and MP3 databases, where different recording levels on different albums can cause the volume to vary greatly from song to song.

            Really Useful!
            I use Normalize to "normalize" MP3's from various sources. I write out the MP3 to a WAV, run Normalize, and then re-encode using a VBR format with Xing (or pick your fav. encoder). Have fixed a number of muted files that way. Would love to see a project that can front-end this process! Keep it going!

            Great work
            This is such a great program, especially the batch
            mode. When processing a whole album, you can
            adjust the volume of the songs while still
            preserving their relative levels, which is excellent.

            Much better than any Windows normalizer I've used :)

            This is one of the easist applications for making audio cd's sound like they were mastered. It is impossible for a 'mix' CD to have the same levels. Thanks for making such an easy to use application that does a perfect job! Thanks for making it free too!!

            Very useful app. I've been looking for such stuff for a while now because
            the MP3's I used to burn audio CD's didn't have the same volume
            levels and I constantly had to adjust the volume knob. Now
            all those problems are gone since I normalize all the MP3's
            used to burn a certain audio CD. Thank you for this nice app.
