AutoTune Toy

Allows you to record and graphically manipulate and pitch correct your voice.

Description

The AutoTune Toy was written to demonstrate pitch correction using Matlab. To be exact, I was watching Nova one night on PBS and there was a segment on Antares AutoTune software. I thought “I can do that in Matlab!” so this is my attempt at just that. This tool allows you to record short segments of your voice and interactively correct the pitch. Given that the tool uses memory to store the audio data, it is only practical to record short (20 second or less) audio fragments, but it is still a lot of fun to play around with!

• MATLAB release: MATLAB 8.0 (R2012b)
• Other requirements: Sound card and microphone

Hi all, thanks for the comments/suggestions! I've submitted a new version of the file which should fix the issues... Glad everyone likes it!!

You can change your call to "wavplay" from

wavplay(A,handles.sound.Fs,'async');

to

p = audioplayer(A, handles.sound.Fs);
play(p);

Great App. A couple of suggestions:

1. To Seth's point, since the App install location (where the README.pdf exists) may not necessarily be where you currently are, I suggest changing the call to open the PDF from

winopen('README.pdf');

to

open(fullfile(fileparts(which(mfilename)), 'README.pdf'));

Notice the use of "open" instead of "winopen". "open" will work on non-Windows as well.

2. Use "audioplayer" instead of "wavplay". This makes it cross-platform.

This is awesome, and so easy to use. There is an error with the App install where the PDF is not found when you click on the help menu.

How long did you do it? Thank you !

[Bryan]

This is very nicely done. Have you thought about making a version that can import and work on a wav (and save the result as a new wav) rather than requiring an active recording?

Simple to use and excellent programming. Looking forward to possible a T-Pain sub routine.
