This Audio Hacker shield project lets you dynamically adjust the audio sampling rate and bit resolution so that you can listen to the effect they have on audio quality. With an Arduino and this simple shield, we can sample audio and manipulate the signal in many...
When you record audio samples to the serial SRAM on the Audio Hacker, the data will be lost when power is disconnected. However, the Audio Hacker uses SRAM chips that allow a small voltage to maintain their contents. The Audio Hacker board has pads where you can...
This simple example project is the same as the 12-bit Sampler, but the audio sample is played in reverse. In the Arduino menu, choose File->Examples->Audio Hacker->SamplerReverse. Record your audio sample with button S1 on the Audio Hacker (top button), and play it...
I like to use my computer’s microphone and audio output when I want to record my voice in the Audio Hacker, but you can also connect an electret microphone using a simple circuit. An electret microphone is handy for applications where you don’t want a...
This project allows you to use the Audio Hacker shield to manipulate an audio signal in realtime by adding an echo effect. This is achieved by constantly recording the incoming signal to memory. When reproducing the incoming audio on the output, we also mix in...
This project is an introduction to the new nootropic design Audio Hacker shield. The first sketch you should use with the Audio Hacker is the 12-bit Sampler. Install the Audio Hacker Arduino library in your Arduino sketchbook, then choose the menu item...
