tried it and was dissapointed, how can we return this, didn't seem to work at all, in fact may have made the file worse

Great for podcast volume control. I found the parameters of "adjust volume with loudness normalization set to -13.0 LUFS" and "enable automatic volume control" to work well with all of my voice podcasts. Not sure what it would do to music. I tried some competing (cheaper or free) products, but this is the only one that worked well for my situation.

I needed this product after purchasing a recessed lighting/bluetooth speaker unit for my shower. Without this product, I could not hear some guests in various podcasts due to the shower noise. With this product, I have yet to miss any spoken words across many different podcasts.

Also, a couple of my podcasts have loud commericals (relative to the normal podcast) inserted automatically at random places that used to cause me to have to yank out my earphones at the gym to avoid ear damage. This problem has also been solved by using this product. Recommended! Show more

I've been using waterproof MP3 player while swimming and constantly suffered from volume issues. Some songs sounded so soft only dogs could hear them, while others almost ruptured my eardrum. I was initially sceptical about paying for an app that basically equalize volume, but at the same time could not find anything free that did it. I have to say that this app is well worth the money. I don't really know about technical stuff like LUFS and bit rates (and find the support pages somewhat difficult to understand), but all I know is that once I converted the songs they all normalized in volume! I like the option of deleting original "non-normalized" songs after converted ones are loaded: this eliminates the need of guessing which are which. There's also an option of automatically add converted songs to iTunes. Very nice app overall. Show more

I have grown tired of having to constantly monitor the volume control. This morning I did some searching and came upon MP3 Normalizer. I first went to the web site to try it out before purchasing and after converting two files, I knew this was a worthwhile purchase! The cost of the app is a steal! I have converted 16 large MP3 files and each file took maybe 2 minutes or less to convert. So easy to use and I didn't have to read several pages of "how to's). I have listened to 3 files and "yes" the volume is normal and stable. The sound is not compromised. Wish I had gotten the app long ago!! Show more

I have copied over 550 songs from records, tapes, CD,s etc. into one file. Some song volumes are soft, low, loud. Many Genres from old classic to modern rock. Now, to the point. I am able to drag and drop one song or all into the MP3 Normalizer box and simply all are done very fast. Plus this app can clip slow beginnings such as from old LP Records. I created a folder called MP3-Normalizer as a destination place for them to wind up. Then copy and paste the whole bunch back where it started. I’m not very computer smart, but this app pretty much does it for me. Oh, it is a MP3 program so all songs going into it must be MP3. So convert any you want and bingo! Show more

First, use Loudness, not Peak, normalization to adjust volume (in preferences, effects) for this app. Now the caveat: The default level to "adjust volume with Loudness normalization" is -15.0 LUFS. This setting is too high, causing high frequency distortion when played back on USB drives. Do NOT use any setting higher than -20.0 LUFS, that is, don’t use any number less than -20.0, and certainly not the default -15.0). With this caveat, I have nothing but praise for this app, a worthy counterpart to iVolume for iTunes m4a files. More versatile, in fact, because it does depend on the software of the playback program (e.g., iTunes) to equalize volume levels among tracks. $9.99 could not be better spent. For the first time in my life I can share music collections on USB thumb drives with family and friends, knowing that they won’t have to ride the volume control. Nice work, Brother Nikolay. You have made an invaluable contribution to the highest expression of humanity: music. Show more

Really like that I can balance the level of my sound files to play in a balanced way. No noticeable audio quality change. Worth it :)

Adjusting/Normalizing Volume Levels across a songlist is what I was looking for. This App was able to do this with ease and save the day for my party. Thanks for a great app !!! Show more

I was fortunate to be able to try the beta version of MP3 Normalizer. I had been looking for an app that would provide some compression of music files for mobile use. Seems no matter how quiet your vehicle is ambient noise usually requires constant adjustment of the volume especially on classical music. With the special processing of voice enabled I normalized an assortment from the Telarc Sampler Series of their Classical and Jazz selections and although I have not yet listened to all of the selections, in my opinion, the app does a good job with compression, making the selections very listenable in the car where constant volume adjustments were necessary with the un-normalized versions. I am sure audio purists would not agree but it does a great job at least for my purposes. I will admit that "Explosions Polka" did tax the app to its limits and overall it works well for what I wanted it to do. Thanks for a great app! Roger Show more

Their discription here and on their website specifically states. "It amplifies too quiet audio and decreases volume of too loud files or their parts automatically.” I tried this app on a single two person recorded interview MP3 file where the interviewer’s voice was too “quiet” and the person being interviewed spoke too “loud”. This app made no modification what so ever to the file I was trying to “normalize” the volume level on. I suggest you try the trial app at their website before spending any money here. Waste of money and time and I atleast want my money back. Thank You, dD... Show more

If you’re looking to boost your overall level output for MP3 files, this is not a good app for this process. Normalization is already an option in your system preferences.

Super easy to use and does the job perfectly. It increases the audio of my MP3 files noticeably and without any glitches. Love it! Thank you ;-)
