    I've gotten duff2013's implementation working: copied the repository into `~/Documents/Arduino/Vocoder, cd'ed into a copy of the "wet" example, and reworked (using various other bits I've been...

    I'd definitely prefer to use something that exists (at least for *this* costume season). I included the two that I found as a down payment on doing my own homework and with the hope that someone...

    Still on the Halloween kick, looking for cool voice modulations.

    Thanks defragster! I've seen the Part_2_03_TFT_Display tutorial which displays the output of a pair of peak filters [SIC?] on the display, that's what gave me hope that I could do a wider...
