Rocking Raspberry pi- Wolfson Audio Card

rohitrangwani

Hi guys

Got my Wolfson audio card this eve , I was exited to see it working.

 

 

There are many options available to us for our karaoke machine design but as the number of options increases ,the choice becomes hard.

There are few aspects of project that I would like consider now.

  1. If wolfson comes ,piface goes.
  2. If external sound card is used ,sound quality deteriorates.
  3. If wolfson is used ,we have to use the customised os available(based on rasbian),and many guys were working on RaspBMC i think.(again a problem)
  4. No choices for choosing other os available,if wolfson card is used.
  5. If you guys dont have any spare memory card (atleast 8GB) you have to go for formatting your Noobs pre-installed memory card.
  6. The SD Card needs to be of Class 6 or higher, especially if you want to read/write high quality audio.(source)
  7. If we use wolfson ,choice of using onboard digital setreo microphones for any purpose you want like voice control.
  8. Multiple sound capabilities if wolfson is used.

 

So, whats we are going to do next remains the question.

Comment your suggestions and queries.

  • I think it depends on the design requirements. If you want the images and text to appear on a large screen for the karaoke, then the PiFace CAD would not be needed as much. Then you could direct the audio out via HDMI maybe, and use the Wolfson audio card for mic input.

    However, some people may prefer to have a small display to choose the song maybe. In that case without additional hardware there is no choice but to connect a microphone through other means, e.g. USB soundcard and not use the Wolfson card.

    If you really wanted both together, then it may be possible to inspect the circuits for both the Wolfson card and the PiFace CAD (since I'm guessing after the registers have been set up in the Wolfson card, then the connections could be used for the PiFace CAD - or maybe there is a chip-select that doesn't clash with both boards - it would be just luck. There is also the option of running two RPI's : ) a bit excessive : )
