Writing a driver for this card: your thoughts?

["Eliot Blennerhassett" <bigblen@xtra.co.nz>]

Those of you who read linux-audio-dev will recognise the following. 
Thanks for your replies over there. 

It should have gone primarily to alsa-devel, but somehow didn't.

Hello, 

I work for AudioScience (www.audioscience.com) 

We make excellent (how could I say otherwise) audio cards. 

The emphasis within the company has been on microsoft windows drivers. 
... but we have a Linux driver, currently proprietary, closed source, that 
exposes this 
(http://www.audioscience.com/internet/download/spchpi.pdf) API. 

(It may be possible to release the host side code, but never the DSP code 
on the cards.) 

I think it would be much better if we had an ALSA driver. 

I'd like some idea how hard it would be to write an ALSA driver either as a 
compatibility layer on top of our existing driver, or from the ground up.  I 
realise that this is rather a broad question, so please consider this an 
invitation to enter discussion, rather than a request for you to go off and 
do a lot of work for me. 

Oh - what do you think of the cards' feature set?  


Some distinctive things about our cards (not all have all features) - they 
have on board DSP.  Code is downloaded by the driver. - they have a lot of 
on board buffer memory (hundreds of K at least) - on board DSP handles 
decompression/compression - mixing - samplerate conversion or multiple 
outputs at different rates - analog and digital audio I/O, balanced drivers
