Wolfson Pi Audio Card

<checks calendar, checks website, repeat for a few days...>

So, any news?

Hi Michael,

After a minor glitch with the hardware we've now got boards turning up at the warehouse in their thousands. Main focus now is on getting the software drivers to a level we're happy with before releasing. We're working closely with the Raspbian team as well as the team at Element14 and we'll keep you posted as soon as we have a firmer date.

I had a  quick look on the Wolfson website but I couldn't see any detailed info about the on chip DSP or how to program it - is this information available ?

Hey, delays happen, but information is always good!

Hi,

Time really is rolling by!

When are you going to sell the Audio Card?  2013,  2014,  2015 ??

If it is  too difficult to program?      Other people appear to have had some success with SPI audio cards on the Rasperry  ---- See  HiFiBerry Mini  by Crazy Audio.

regards

Hi Patrick,

thanks for your post. Please see my reply to Michael, hopefully this goes some way to explain the delay.

Cheers,
Eddie

Hi, Is there any news?

Hi all, OK lots of work over the holidays as well as last week and we're almost there.

What we've got left to do is release the new Kernel, finish testing the software image and get the documentation completed.

Beyond that we need to get the usual support and PR elements in place and we should be good to go.

Again I'm loathe to commit a date too early but we're on track to start shipping before the end of Feb.

Cheers,
Eddie

Thanks for the update!

Hi Michael,

At the heart of the WM5102 Audio Hub is a 50MHz proprietary Wolfson Audio DSP (ADSP). It is a key element defining the unique functionality of the part and differentiation vs other audio solutions. It was designed for ultra-low power processing of audio functions such as voice trigger, noise cancellation (transmit, receive and ambient), audio playback products, speakerphone enhancement and many more audio and other sensor processing. As well as running Wolfson algorithms, we open the core up to 3^rd Parties to port and develop solutions to it via the Wolfson Partner Programme.

We are working hard to make ADSP open to all of our customers by putting in place high quality hardware and software tools as well as the documentation and engineering support required of such a high performance core. It's going to take some time to get this into shape and won't happen overnight. We will keep the community informed of progress in this area. The reason we’ve chosen this chip for the board as opposed to a standalone Codec is to provide the latest in ultra-low power audio DAC & ADC technology with multiple audio inputs/outputs to suit portable as well as mains powered applications and to give us a platform to grow in the future.

Hey, Eddie!

Thanks for your  update！Does the card have AEC function？And what's the maxmum tail length

it could deal with？

Hi Jianguo,

There is no AEC on the card.

Hi Jianguo,

There is no AEC on the card.

Hi, Eddie

I have got the board. But there is only the board in the packaging. Where could I get the related resources, such as data sheet,user manual,driver,opensouce code,etc. Thanks!

Hi all,

by now you should (I hope!) know that the board was made available to buy in Asia & Europe yesterday, with sales in US coming in mid March, pending certification.

With the availability, all the software drivers, documentation and the free HD music tracks from our partners HDTracks was also loaded onto the website.

We'd like to say "thank you" to everyone who contributed to and viewed this thread over the last few months. Thanks to you for your interest and your patience.

I really hope you all now purchase the card and enjoy using it. We also hope that you'll continue to ask questions, share information and give feedback on this forum as you continue your developments.

We can't wait to see the uses that people come up with for the card and for the Wolfson devices on it. We genuinely believe that HD Audio should be standard and that Voice should become the natural user interface on 100s of applications.

Regards,

Eddie

Hi all!

I just placed an order

My aim is to create an ultra-portable platform for Outside Broadcasting. I'm Head Technical Guy at an FM radio station and our present solution for live broadcasts "on the street" is big, cumbersome and somewhat user-unfriendly. The Pi itself has already proven itself as a streaming audio server and client, but I've had a fair amount of problems with USB audio interfaces. It'll be interesting to see what the Wolfson can do for me.
