When we download music from the Internet, we risk that the files that we download have been badly converted or ripped, or that they have been badly equalized or with an extremely low gain, so it's never a bad idea to have an application like Mp3Doctor.
This tool allows us to normalize MP3 and WAV files, edit the tempo and tone of each file, modify the equalization (being possible to save customized presets), resample songs (in case they have different bitrates) and eliminate the empty spaces of each song. The program allows us to modify the files individually or using batch processing, thus allowing us to edit complete albums all at once.
The interface is really clear and simple, because it has all the controls accessible from the main window and, furthermore, it has four different skins with which you'll be able to customize the application's aspect. If you want a program with which you can make your songs sound in the tone and at the volume that you want, download Mp3Doctor right now.
