Great for podcasts

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!

MP3 Normalizer enhances the sound quality of MP3 files, supports Peak and Loudness (EBU R128) Normalization methods, and Automatic Volume Control for speech record processing.

Simultaneously with normalization, MP3 Normalizer can apply Audio Effects, such as Silence Trimming, Fade-In, and Fade-Out for improved playback.

MP3 NORMALIZER IS AN IDEAL OPTION FOR:

There are just some common cases of using MP3 Normalizer. However, you can apply it for a much more comprehensive range of purposes.

INPUT FORMATS

MP3 Normalizer supports .mp3 and .wav file formats. You will have a new MP3 file with an adjusted volume level and applied audio effects as an output.

Please note that if you would like to normalize audio files of other formats, you must first convert them to MP3. We recommend using To MP3 Converter for this.

EASY AS ONE, TWO ...

To normalize your MP3 files, drop them into the application icon or window. The application will then notify you when volume adjustment is complete. MP3 Normalizer supports batch processing, allowing you to process a single file or an entire branch of folders at once.

TRUE BATCH PROCESSING

MP3 Normalizer allows you to adjust the volume of an unlimited number of files and folders with a single click, supporting multiple simultaneous normalizations. If you process an entire branch of folders, MP3 Normalizer will replicate the structure of the source folders. It is especially convenient if you need to adjust the volume of an entire music collection.

CUSTOMISABLE NORMALIZATION METHOD

By default, MP3 Normalizer analyzes every audio track and applies the Peak Normalization algorithm with a Target Level of 0 dBFS. You can normalize either by Peak or Loudness (EBU R128) methods by choosing the required method in Preferences. To improve the quality of voice records, we recommend enabling Automatic Volume Control, which applies special processing to voice records.

AUTOMATIC OUTPUT SETTINGS

MP3 Normalizer estimates Bit Rate, Sample Rate, and Channels, and applies optimal settings to output MP3s. As a result, it guarantees the best possible sound quality, saves your time, and hard drive space.

If you would like to convert to a special Bit Rate, Channels, etc., change settings in Preferences.

*Note, we advise selecting a Bitrate at 128 kbps, or lower, meaning if you burn normalized MP3 files to CD and listen to it in your car. Some CD car players cannot read MP3 files with Bitrates higher than 128 kbps.

AUDIO EFFECTS

MP3 Normalizer can automatically apply fade-in and fade-out effects, as well as trim silence at the start and end of audio tracks. To use the effects simultaneously with volume adjusting, enable them in Preferences.

TAGS TRANSFER

MP3 Normalizer transfers all tags from the source .mp3 or .wav file to the normalized file. If you would like to check or modify tags after normalization, please use the Tag Editor.
