Wolfson Audio Card, produced by Element14 in collaboration with Wolfson, offers Raspberry Pi® users similar flexibility to a PC sound-card to capture audio alongside their camera, and experiment with stereo digital capture and playback. This audiophile-quality add-on is great for intense audio experimenters.
Wolfson Audio Card is based on Wolfson WM5102 audio hub codes. The WM5102 is a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices. It combines wide-band telephony voice processing with a flexible, high-performance audio hub CODEC. The WM5102 digital core provides a powerful combination of fixed-function signal processing blocks with a programmable DSP.
Wolfson Audio Card is ideal for applications including VoIP, gaming, high quality audio capture, digital audio processing, and audio rendering, XBMC and media streaming, internet radio, networked audio, and DLNA audio rendering.
Note: Wolfson Audio Card comes with a very small translucent screw that helps connect it to the Raspberry Pi. Be careful when you open your package. Only for use with Rev 2(Model A or B) Raspberry Pi's with the P5 Header.
