HD Audio Server - Raspberry Pi Kit (Raspberry Pi Model B)
The HD Audio Server kit is aimed at supplying all the hardware needed for a project which involves setting up a WiFi server for web/streaming/audio applications using the Raspberry Pi.
The RASPBERRY-MODA plus 256M is a credit card sized single board computer that plugs into your TV and keyboard. This is a little PC which can be used for many of the things that desktop PC does. The design is based on Broadcom BCM2835 system on chip with 700MHz single core ARM1176JZF application processor, Dual Core VideoCore IV Multimedia coprocessor and 256MB RAM. Raspberry Pi A plus board is powered with 5V micro USB connection and work on reliable operating system such as Raspbian, RaspBMC, Arch Linux, RISC OS, OpenELEC and Pidora.
The Wolfson and element14 introduce an audio card to offer Raspberry Pi users the ability to capture audio alongside their camera, and experiment with stereo digital capture and playback.
Raspberry Pi, whilst doing a fantastic job of being a small and powerful computer, does this by a number of compromises. One of those is the limitations on its audio capabilities. Out of the box, Raspberry Pi provides good quality audio across the HDMI link, lower quality stereo audio by way of its 3.5 mm stereo jack, but no capability to connect microphones or other external audio sources, such as attaching directly to loudspeakers.
The Wolfson Audio Card solves this by providing similar audio flexibility that would be provided by a PC soundcard. Not only this but the Wolfson Audio Card was produced in partnership with Wolfson, the premier audio solutions chip company, to produce superior sound capabilities for the Raspberry Pi.
The 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 wideband telephony voice processing with a flexible, high-performance audio hub CODEC.
