SparkFun will be closed Nov 26th and 27th for the Thanksgiving holiday. Orders placed after 2:00pm MT on the 25th will ship out Monday the 30th.
Description: The Spectrum Shield enables your Arduino with the capability of splitting a stereo audio input into 7-bands per channel. You can then read the amplitude of each channel using the ADC on your Arduino allowing you to control everything from LEDs to motors, pumps to relays, or even fire, all with sound. With this shield you will be able to have almost any project be able to react to music or sound!
The Spectrum Shield features the MSGEQ7 graphic equalizer display filter. Two of these ICs allow you to split a stereo audio input into 7-bands (per channel) and read the amplitude of each using the ADC on your Arduino. The shield is populated with two 1/8" stereo jacks (like you would find on a pair of headphones). One serves as a stereo input and the other is a pass-through output which allows you to connect the Spectrum Shield in-line between your audio source and your stereo system without interruption. This revision of the Spectrum Shield has been updated to the Arduino R3 layout but still requires you to solder on your own headers (check the Recommended Products section below). This shield can be used to create sound visualizers, detect patterns in music or add sound activation to your microcontroller projects.
Note: This product is a collaboration with Ben Moyes of Bliptronics. A portion of each sales goes back to them for product support and continued development.

I am very disappointed in this board. There is so much that needs to be done in software to eliminate the noise and then artificially inflate the input readings that this board is nearly useless for anything other than maybe giving four or five levels of actionable values. I’ve read in many other places that there are much better ways to hook up and utilize the MSGEQ7’s. Do yourself a favor: since this board requires some soldering anyway, spend a couple bucks and get the IC’s themselves and a couple other components and build something yourself. Skip this dud. I will be desoldering my Teensy from this board ASAP. I heartily wish I could return it.
Hi, Please drop us a line directly. We’ll be happy to work with you on this. Thanks - https://www.sparkfun.com/returns
Nice little board that does a specific thing (reading stereo audio levels over 7 different frequency ranges) very well. Easy to use with an Arduino, and the shield has enough room to mount a pro mini board right on it. The audio in and audio out is a nice feature (allowing stereo audio through).
