In general, audio normalization is the process of adding constant amount of gain to bring the average or peak amplitude to a target level.
Peak normalization is a specific type of normalization, where the gain is usually applied to bring the highest sound (PCM sample value or analog signal peak) to 0 dBFS, the loudest level allowed in a digital system.
Peak normalization with BatchMP Tools is as easy as:
$ bmfp normalize 3 media files to process Processing 3 tasks with pool of 2 worker processes Already normalized: /Users/AKPower/Downloads/08 Queen Alice.mp3 Already normalized: /Users/AKPower/Downloads/Born Barnstomers.mp3 Done processing: /Users/AKPower/Downloads/Bird in Hand.mp3 in 0:00:06.19 Finished running 3 tasks (Succeeded: 3, Failed: 0) Total running time: 0:00:11.33
bmfp normalize command in its simplest form runs over all media files in a given directory, processing all media files that are not yet normalized.
