: It optimizes audio based on peak levels or perceived loudness (RMS).
Sound Normalizer allows you to modify the two sound channels separately. If one side of your audio is louder than the other, you can balance them here. You also have the option to preview the changes in real-time by listening to the file before applying normalization.
