Sfortunatamente per chi come me lavora come fonico in uno studio di registrazione, la voce dei cantanti può spesso rappresentare un problema nei casi (troppo frequenti) in cui l'intonazione è ben lontana dall'essere precisa.
Per questo da diversi anni esistono strumenti sia hardware che software dediti alla correzione dell'intonazione della voce spesso noti come autotune .
One of the most common is the ' of Antares autotune years that corrects the bad entries that are followed to the microphones of the recording studios all over the world.
Even in free field are such tools, they are plugins LADSPA and LV2 use through your favorite host, and of course within Ardour , their names are Tom Autotalent Baran and Vocproc Igor Brkic.

addition to corrective action, these tools allow different creative effects to their parameters is assigned when an extreme value: an example of creative effects can be found here
Below is some sample:
