I didn't see my last post to the list, a reply to the post regarding
"$170 SHARC's"; so here goes again.

Who knows anything about the "$170 SHARC" board from Analog Devices?
Below is the communication I received regarding the $1000 hand-wired
prototype cards being offered by Analog; this is the only offering I
know of. Have I missed out on something? (I presume this was only
hearsay/rumor.)

$50 shipping?  For a sound card and some software?

Hi,
    Whilst looking into the effect of the first fraction of time upon 
perception of the whole timbre of a sound I have been playing with 
some very simple FM synthesis scores. I'm very puzzled now. The .ORC 
that follows is a standard single carrier FM orchestra, and two 
.SCO's follow. I thought that the difference in tone and timbre 
percieved in the two was a result of the initial time segments 
differing, but the difference is an actual characterisic of the whole 
sound. If the resulting sound files from each are edited to have the 
first part removed, they still sound very different. What am I 
missing here, how can they be physically different in the latter 
stages ??

Just found the following on Analog's web site:

        http://www.analog.com/products/sheets/ADDS2106XSHARCEZKITLITE.html

"How much does it cost to get everything you need,
including a C Compiler, to evaluate SHARCTM
DSPs and develop applications for one of the most
powerful 32-bit digital signal processors in the world? Just $179 US for the
SHARC EZ-KIT LiteTM. [...]"

Be patient; for some reason Analog's web site seems dog slow.  Or perhaps it's
the connection to Europe.

Bye,
        Jens.

You should provide a complete score, not just the f-cards. Otherwise no-one
can test what you're doing.

You mean DirectSound, perhaps ?

There shouldn't be any problem with "1 input/output" limitation. It means
"1 default input, 1 default output". You can specify device other than
"default" in waveOutOpen/waveInOpen (?).

In DirectSound you can enumerate all wave output (or input) devices, and
use corresponding ones (you get a pointer to the IDirectSound interface,
each of them represents one sound output device).

All of these are AFAIK, of course. My memory isn't very precise :(

Software which manages quad output is very rare, but I can run two or
three instances of a wave editor (Cool editor) in parallel, each one
with a different input and output device. These three instances can be
activated with my 3 cards giving up to 6 channels in input and in
output. The problem is that I create 3 different stereo wav files and it
is difficoult to play them with a good syncronization.

Current version of my Win95 Csound  (1.731) does not support realtime
input. Next version (1.8) will support it. I'm waiting for the sources
of the definitive release of 'official' Csound 3.47 to include all new
opcodes before uploading it to the Internet.

	In FM, the starting phase relationships are going to have an
effect throughout the length of the note.  So if you have two notes, one
which is modulated slightly faster just at the beginning, when they settle
down into the part where the should seem to be the same, you are almost
certainly going to have a phase difference between the two modulators.
The only way to avoid this is to do a calculation that ensures that your
changes at the beginning result in no phase shift in the later sections.

Looks great but any idea as to how useful this card would be for the upcoming new
commercial version of csound?   Or the current free version for that matter?

Also, what about using it from Linux?  Would this ONLY be useful if I were using
it from dreaded Win95?  Can I use this as my primary soundcard for standard audio
applications in win95/linux?   Comments....?

Thanks
