Synthino Arduino-based Synthesizer

The year 2014 has been the year of synthesizer design for nootropic design! After releasing the Audio Hacker Arduino shield last year, I continued to get more interested in audio processing. I started designing audio synthesis software for the Arduino, and by...

Audio Hacker Voice Changer

This Audio Hacker example shows how you can manipulate audio to radically change recorded samples. This project uses a technique called granular synthesis, to raise and lower the pitch of a sample. It’s easy to change the pitch of a sample by playing it slower...

Audio Hacker Drum Machine

This project really pushes the limits of what you can do with audio sampling on an Arduino! It is almost the same as the 3-Track Looper project so I recommend you read that first. Now instead of controlling a loop delay with a potentiometer, we can lay down a track by...

MIDI Triggering for Audio Hacker

This project shows you how you can use your Arduino+Audio Hacker as a MIDI instrument. The Arduino MIDI library makes it easy to read the MIDI commands that arrive on the Arduino serial port. I used a Rugged Circuits Flexible MIDI Shield for this project because it...

3-Track Looper with Audio Mixing

This Audio Hacker project is similar to the Four-Sample 12-bit Sampler project but now we can loop the samples and mix them together. Now we call them “tracks” instead of samples. It demonstrates how audio samples can be combined so that they are mixed at...

Four-Sample 12-bit Sampler

This Audio Hacker project is similar to the 12-bit Sampler, but divides the Audio Hacker SRAM into 4 banks so that you can record and play back 4 different samples. To make the hardware setup easy, we’re using the DJ Shield because it has 5 buttons. The 4 memory...
