reTune gives you full access to the pitch content of your audio samples and lets you map each input pitch to any other pitch of the chromatic scale – all in real time.
This allows you to re-tune the sound to any target key (for example, from D major to C minor) or use it as a creative tool to change the pitch content in any way you like. If you are not sure about the key of the input audio, you can let reTune estimate the key for you.
