Frequency Filtering with the Audio Hacker Shield

The Audio Hacker shield for Arduino lets you do some cool things with digital signal processing. This new project shows how a fairly simple Arduino sketch can implement a low-pass filter, high-pass filter and band-pass filter. A low-pass filter allows low frequencies...

Using a Video Experimenter as MIDI Controller

This simple project shows how a video signal captured by a Video Experimenter Shield can be used to send MIDI messages to a synthesizer. A small camera module is connected to the input of the Video Experimenter (the red wire in the picture is for powering the camera...

Synthino XM Polyphonic Synthesizer Now Available for ALL

After a successfully funded Kickstarter campaign, the Synthino XM is finally available to the whole world. The Synthino XM is by far the most sophisticated device we’ve design here at nootropic design. We had a lot of help from our partner in this project,...

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...
