+//This documentation is for the old version of the Shades Audio Sensor. It was sold as a pre-production version and has been replaced by the Shades Audio Sensor V2 (which has a sensitivity switch).//
 The [[http://macetech.com/store/index.php?main_page=product_info&cPath=15&products_id=61|Shades Audio Sensor]] is a small circuit board that can be soldered to either the LED Matrix Shades or the RGB Shades. Since the connector pinout is different between these products, the Shades Audio Sensor must be configured with a solder jumper on the back. The built-in microphone picks up ambient sound and music, which is amplified and fed into an MSGEQ7 seven-band frequency analysis chip. The MSGEQ7 provides analog voltages to the RGB Shades or LED Matrix Shades corresponding to the sound levels present in each of the seven frequency bands. This enables the microcontroller on the Shades to analyze sounds and display various types of audio visualizations.
