I seem to have made the mistake of thinking that Seeed studio boards would offer source code access so that we can fine tune the application to our needs. I have both a respeaker array v2 (4 mic) and the current respeaker-lite. Neither has source code support from Seeed and I'm wondering if I can use XMOS source to provide a route. I have a few questions:
1. On paper, the 4 mic respeaker array v2 has longer far-field performance (5m instead of 3m) and in onmi-directional. However, it's also older silicon and sw. From a SW perspective, which HW would be the best to use in a voice assistant with media player application?
2. Is the source code for the 4-mic available. When I tried to access the code it stated that vocalfusion SW is only available with a commercial license. Is there a way to open up support for the respeaker v2?
Thanks!

Hi,
firstly I can't comment about Seeed studio firmware and access. It's likely they have made changes from the XVF3000 reference design - I am afraid we don't have visibility of this since it's external to XMOS and is Seeed studio's business. The source code for the XVF3000 (which targets our dev kit) is still available but you will need to contact XMOS directly to have the license added to your account.
What I will mention however is that, for new designs, it is highly recommended to move to the XVF3800 which uses a much higher DSP performance device (supports vector 8 x 32b DSP and FFT acceleration) allowing Teams and Zoom certification to be achieved which are very tough goals. It also will have a much longer lifetime as XVF3000 has an EOL notice already in place.
There is a note on the website here: https://www.xmos.com/xvf3000/ to that effect.
XVF3800 is available as source too so you can make changes as needed (extra DSP, IO config etc.), but again, you'll need to file a support ticket to request this access.
Hope that helps.
