Mac users interested in Macbook pro sound equalizer settings generally download:
Equalizer is an application to assist when capturing and restoring audio from gramophone records whose equalization and/or speed does not match your equipment. It has been developed over a period of many years. There is a user manual that is part of the download package. Equalizer will not operate on compressed audio files, such as MP3, and there are no plans to incorporate such a feature.
