Wolfram Knowledgebase Curated computable knowledge powering Wolfram|Alpha. Wolfram Universal Deployment System Instant deployment across cloud, desktop, mobile, and more. Farnell Element 14 also suggests using the Raspberry Pi as a high-definition audio recorder, or developing and playing online games that allow in-game audio so you can chat with friends.Wolfram Data Framework Semantic framework for real-world data.

These are just three of the projects that first come to mind. There are no technical limitations with the Pi or Mathematica currently barring the Raspberry Pi from playing sound (through its analog audio port or HDMI). By using the Wolfson as a go-between, it’s possible to get higher definition sound with less strain on the Pi. But when the Pi has to process sound itself, it becomes slower and lower quality than it would be on your average computer. It was already possible to turn your Raspberry Pi into a remote Pandora music station by hooking it up to a pair of speakers. Raspberry PIs have built in EMI supression functionality for reducing external noise using Spread Spectrum Clock Signal (SSCS). Attach the sound card to the Raspberry Pi and then follow the tutorial to set up voice command software for the same effect. Instructables user Janw used a vintage ‘50s intercom to turn his Pi into a “ Raspberri Personal Assistant.” But with the Wolfson Audio Card, you no longer need to go antiquing to complete this particular project.

Make cheap phone calls over the Internet by configuring your Raspberry Pi for Voice over Internet Protocol (VoIP). Here are three projects you can make with a Wolfson Audio Card and a Raspberry Pi: VoIP for Raspberry Pi

External sound processing takes the load off the tiny Raspberry Pi processor and makes it sound better, opening up new DIY capabilities for the Pi. The board also hosts four 3.5 mm jacks-one for a headset/boom mic combination, one for mic input, one for connecting to devices like iPods and phones, and one for connection to amps or speakers.īut the most important feature of the new sound card is that it processes sound itself. It features an onboard microphone and a Wolfson audio processor that supports high-res audio up to 24-bit / 192KHz. The audio add-on board fits directly onto the Raspberry Pi’s P5 pins. At $33, the card costs nearly as much as a Raspberry Pi, and it’s even almost the same size. The Wolfson Audio Card is being produced by Farnell Element 14, the same UK company that also manufactures the Raspberry Pi. The makers of Raspberry Pi have just released a sound card designed especially for the tiny, $35 Linux-based computer.
