Step 13Uses? Shaker Percussion
There are many possible uses for a sensor with Audio Input and Output. One of a feasible field is sound instrument. We made a Shaker Percussion with this instructable. It can make use of its precious samping resolution and sampling frequency.
Here is the setup. You will need split you audio output with stereo to dual mono cable. Connect an Accerelometer (Kionix KXM-52) to the board. It's 3-axis but in this time we just use one axis of the accerelometer. One is connected to power, one is connected to signal, and the last is connected to ground. On one channel you connect the board, and on another, you connect a speaker. It would be nice have a mixer between the audio output and the speaker to separately control the volume of the percussion.
In your software, you add a noise generator, and a volume to your basic patch. You also need an adjustment to fit the value from the accerelometer to the volume of the noise generator. Now, you can finely control the noise generator like a shaker percussion!
Here is a MaxMSP patch.
