Sound Normalizer

Sound Normalizer is a powerful software program for adjusting the volume of audio files. It helps you to normalize the loudness of your audio recordings, reduce the size of MP3 files and produce a more consistent sound without losing ID3, FLAC, Ogg and MP4 tags. Sound Normalizer provides a wide range of features and functions to help you get the best sound possible from your audio files, including:

* Test Audio Files: Sound Normalizer tests your audio files and shows their volume level in percent or decibels, so you can see which files need correction before you change them.

* Adjust Loudness: Sound Normalizer can adjust the loudness of any audio file to a consistent volume level, allowing you to easily compare different recordings.

The benefit of using Sound Normalizer is that it brings audio files to a consistent volume level, so all tracks play back equally loud.

* Peak and RMS Normalization: MP4, FLAC, Ogg, APE and WAV files can be normalized by peak level or by average (RMS) level; MP3 files use RMS normalization.

* Per-Channel Processing: the test and the normalization can be done separately for the left and right channels.

* Many Formats: Sound Normalizer supports MP3, MP4 (AAC, ALAC), FLAC, Ogg, APE and WAV files, including many WAV codecs such as PCM, ADPCM, GSM, A-LAW and u-LAW.

* Direct MP3 Editing: the volume of an MP3 file is changed directly, without re-encoding it with an MP3 encoder and without APEv2 tags.

* Format Conversion: the program converts between WAV, MP3, MP4 (AAC, ALAC), FLAC, APE and Ogg using the LAME, FLAC, Monkey's Audio, Ogg Vorbis, FAAC and Apple ALAC encoders.

* Batch Processing: Sound Normalizer has a batch processor for batch testing, batch normalizing and batch converting of whole lists and folders of files.

* Tags and Player: you can edit ID3, MP4, FLAC and Ogg tags and listen to your files in the built-in audio player.

Sound Normalizer is a useful tool for adjusting the loudness of your audio files to better suit your needs. Whether you want to fix a quiet recording or make a whole music collection sound the same volume, Sound Normalizer does the job in batch. It is shareware: the trial works for 30 days, and a license costs 34 USD.
