I have a project in mind where I'd like to stretch out the syllables of pre-recorded words - either in a sustained way, or with a stutter. For example, the word "sustained" might sound like "ssss-usss-taaaained", or "sust-t-t-t-a-a-a-ined" etc. I would not want the pitch or sound quality to be affected.
What tools can be used to achieve this? I'm planning to end up in the Max/MSP environment but I'm not there yet. Are there VST's that do this kind of stretching or rendering of a recorded sample/file ?
