From the InTune web site:

The main purpose of the program is correction of freshly recorded musical material, particularly vocal, woodwind or brass instrument recordings, which are
highly susceptible to impurity in tune. Apart from that, InTune can be used to remove noise, edit dynamics and timing or analyse
the frequency spectrum of any sound file.

What InTune can do for you?

InTune saves hours spend on recording just to improve minor imperfections. Get your recorded sound file and let InTune do the
rest. It will analyse precisely musical tune and amplitude of the record. You just make a judgement how to change the sound.
InTune will satisfy your wishes in no time. You don't need to type any numbers to change the pitch or amplitude, just drag it with
the mouse. Don't worry if you out of the rhythm, use time link feature of the program to say when the note should begin or end.
InTune will make a time shift without changing a pitch and a colour of the sound. InTune also removes unwanted noise from the
record using sophisticated Fast Fourier Transform method. The composer can be creative with InTune. The possibility of
experimenting are endless.
