MP3 Doctor is an editing tool that lets you check, modify, and improve your MP3 and WAV files. You can repair imperfect songs or modify them with trimming, equalizing, and resampling. The goal is to let you maintain similar quality, volume, and sound on all your MP3s. In addition, the program converts MP3 files to WAV and vice versa. You can modify hundreds of files with one click using the batch mode, or use single mode to process one file at a time. Moreover, the program can handle ID3 tags of MP3 files. The Normalize function allows you to get the lower parts of a song to higher levels and to standardize your MP3 collection. The Karaoke feature lets the user remove the vocals of an MP3 or WAV file. The Pitch and Tempo features let the user change tempo (BPM) without changing the pitch, or vice versa.

Version 5.10.95 improves decode feature.
