Anyone know of a good quality robot voice changer that will take a=20 headphone-level signal, and spit out either a headphone level signal or=20 an amplified signal? The ones I've found so far get poor reviews for=20 sound quality and I feel like the basic on-board amps are a significant=20 part of that, so unamplified is fine and I'll add a separate amp. This=20 will be used for a robot project, and the voice needs to sound like a=20 friendly robot that should appeal to kids. Though I would prefer a pre-built device (as I'm on a very tight=20 schedule), I'm tagging this as EE in case anyone has a good circuit or=20 kit) for this.
