Sound Normalizer is intended to adjust the sound volume of different types of media files, an operation called normalizing. Luckily, this tool supports practically any type of video and audio files, such as MP4, MKV, FLV, AVI, RMVB, WebM, MOV, WMV, MPG, MP3, WMA, AAC, M4A, OGG, FLAC and WAV.
Good news is that the application supports processing batches of items. In this respect, all you need to do is drag and drop the intended files onto its window. Next, you can make the adjustments and proceed to normalize. Regrettably, the tool offers poor feedback while the process is going on, so you do not really know what it is exactly doing at the moment.
The processing is very fast, although the time it takes depends on the number of files to normalize. Luckily, all the original metadata, including album covers, is kept. Likewise, it retains the source directory structure. Finally, the tool integrates with iTunes and lets you import the resulting files to your local library automatically.
The application works perfectly most of the time, but not all the time. In this regard, it seems to have problems normalizing certain types of files. Besides, compared with other similar tools, it does not support any type of effects other than normalizing.
All in all, it is excellent that there is a tool like Sound Normalizer to make all our videos and songs have the same volume, which saves us from continuously needing to readjust the volume level. The product can be bought from the Mac Store at a very reasonable price.
