NorQualizer is a smart self-adaptive equalizer / normalizer which automatically processes multimedia files (e.g. videos and audio tracks) to obtain MP3/WAV libraries where all tracks sound similar in terms of audio spectrum (bass/treble profile) and volume level. Especially useful for preparing audio CDs as well as audio MP3 libraries / albums from various sources, NorQualizer prevents the listener from having to do annoying equalization and volume adjustments each time that he plays a different audio track. Note that NorQualizer is not intended to be an audio FX generator. In other words, it adjusts the track loudness as well as the bass/treble profile, so that you don't have to change your player/equalizer settings again and again to keep it sounding as you want. All tracks will look like from one same album. NorQualizer is user-friendly and much faster than any complex manual process which could be led with a linear audio editor. It also allows you to perform in one user step: The eventual audio extraction of videos, the smart normalization and the final MP3 re-encoding.
