In mp3-2-wav the program name speaks for itself. The free converter converts without much effort MP3 and WAV files. Thanks to a batch mp3-2-wav performs this task for any number of sound files in one go. If required, the converter simultaneously performs a so-called normalization. This feature is similar to the volume of the selected track to another. mp3-2-wav puts the converted MP3s on request into a separate directory. Thus, the user avoids overwriting its original risk.
