MP3 Doctor is an editing tool that lets you check, modify, and improve all your MP3s and WAVs in several ways. 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 existing MP3s. In addition, it converts MP3 to WAV and vice versa. You can modify hundreds of files with one click using Batch mode, or use Single mode to process one file at a time. In addition, it can handle ID tags of MP3 files.
The Normalize function allows you to get the lower parts of a song to higher levels. The Karaoke feature lets the user remove the vocals of an MP3 or WAV file. Some other sounds of the song can also be removed by using the Karaoke function. Pitch and Tempo features let the user change tempo (BPM) without changing the pitch, or vice versa.
