Introducing the Audio Codec Shield for Arduino and Maple

Ever wish you could do serious DSP on your favorite open-source AVR development platform?  We are very proud to be able to announce the availability of our new Arduino shield for the Wolfson WM8731 audio codec as well as code libraries for both the Arduino and Maple programming environments.  To top it all off (triple-feature!), the new libraries and a bootloader have been adapted for the MICrODEC, marking our first official release in C for the Audio Codec Shield’s big brother.

At only $44, we hope that many of you readers out there in internet-land will see the way to accepting some of these little guys into your hearts and homes (and pedal-rigs).

The Audio Sniffer store is now open!

But what is the Audio Sniffer, you ask?

It’s our new kit for an open source circuit debug tool. Think of it as an oscilloscope for your ears. It has a high impedance input which won’t change your circuit’s behaviour, and a low distortion headphone amplifier output, so you can hear the slightest disturbances. It lets you listen to signals as small as a few millivolts, and as large as 60V.

Go to the Audio Sniffer page for more details, and mail us or post in the forums if you have any questions.
