My immediate wish would be for 8 in x 2 out so I could
get rid of the
mixer (just keep a simple mic amp) and more precisely -and repeatably-
define the input levels.
Later it would be nice to have both more inputs and outputs so I
could bring in another rarely used synth and start to experiment with
surroundsound etc. I should also point out that I also put 2 softsynths
into the mix.
I've been working at 44.1kHz 16bit up to now for ease of producing CDs
(not that I've sold any), but rather think I should be moving up to
48kHz 24bit
Ok, let's say you defines the goals, and I define "the next step"
towards thoose goals. Is that ok with you ?
############
My thoughts would be that a first move would be for a 2 in card with
ordinary unbalanced line level inputs, not worrying about noise level
but trying to get a reasonably clear idea of THD as well as hammering
out a communication protocol.
My programming knowledge is limited, as are my hardware facilites.
Ok, that would be my job then.
I can however test things out
Perfect.
I have an analogue sine/square/triangle
generator with less than 0.01% sinewave distortion (100Hz-10kHz),
Great, I lack one of thoose.
pretty
clean square response and linear triangle output. I used to use this for
testing amplifiers, along with a twin T notch filter, scope and valve
voltmeter.
Ok, you do the testing.
I would be happy to buy a made-up development board
with initial
programming done, and then work in parallel with developers testing and
improving both the software and hardware.
*********
Would this project plan be ok:
software and hw: Karl
testing and spec's: Folderol
publication via web: anyone??
git repo: git://aspodata.se/openhw.git
mailing list: hopefully this list, else I put one up at my site
web site: ??
intial platforms (both by Atmel):
. ATNGW100 (cheap), and
. AT91SAM9260-EK (expensive)
Next step:
. set up development platform
. simple test with spi and shift registers
Regards,
/Karl
