Posted in Holiday Hacks, Musical Hacks Tagged adafruit wave shield, arduino, halloween, voice changer Post navigation In all, a very cool project for your Halloween costume that’s also a very good introduction to DSP and real-time audio modifications with a microcontroller.

The completed build incorporates a 10k pot to dynamically change the timbre of the voice changer, as well as an Adafruit Wave Shield to play back a few pre-recorded sounds of lightsabers clashing. ’s voice changer operates on the same principle by recording sounds from a microphone into a circular array and playing them back at a different rate faster if the desired effect is a Munchkin, and slower if this year’s Halloween costume will be a Sith lord. Likewise, playing a single at 33 or 16 RPM means those once dulcet tones are now recordings of tormented souls in an acoustic hell. If you’ve ever played with a turntable, you’ll know playing a 33 RPM record at 45 or 78 RPM turns your treasured copy of Dark Side of the Moon into a lighthearted aural experience with a pitch that is much too high. In an effort to match his voice to his costume, over at Adafruit (and former Hackaday alumnus) put together an Arduino-powered voice changer to give his voice the gravitas of or the lightheartedness of a member of the Lollipop Guild. Halloween is just around the corner, so of course we’re looking forward to a bunch of awesome costumes put together by Hackaday readers.
