| That's funny; I eco'd the ADC70H, a version of Imblum's design to do
conversion to disk on a pdp11/70, and you want a little amiga to do it.
Sorry, don't know of any h/w.

| Of course this depends on the speed that you sample but the Amiga can
keep up with writing samples direct to the floppy disk on the Fly (Not
bad for a LITTLE computer hey!!). Unfortunately I hav'nt seen any
software that does but it is'nt impossible.
If you want to go all the way you could write your own Drive code to
write track by track. You culd fit a bit more data in this way by not
worrying about Data headers and so on.

| 3733.3 | Good reason for delayed 2.0 for the 500... | FENRYS::mwm | Mike (Real Amigas Have Keyboard Garages) Meyer | Mon Apr 30 1990 19:45 | 17 |
| re .1
I don't see any problem with writiing software to digitize direct
to disk. The hardware is common (Perfect Sound is about $70, mail order).
Disk speeds on Amiga's top out at 800K per second or so through a good
DMA controller (ICD Advantage). Since the sampling hardware tends to
stop at 30K samples per second, the disk is plenty fast enough to get
the samples to disk in realtime.
The problem is, can you do both at the same time. Since I've got the docs
on the digitizers, and such would be usefull to me, I'll see if I can make
it happen in the software I'm going to start working on this week (providing
I get the mg3beta4 done in time!)
Should be fun....

Re. -1
You have the docs (Source I presume ) is this still PD ?
Or did you have to register for it ?
Can it be uploaded, (depending of course on the above ) ?

| 3733.5 | Call SunRize | FENRYS::mwm | Mike (Real Amigas Have Keyboard Garages) Meyer | Mon Apr 30 1990 20:52 | 20 |
| I called SunRize industries, explaind that I had a PerfectSound 3.0 and
wanted "programmers documentation, or sample source, or some such." The
offered to let me talk to the "technical staff", and send me the soruce
to Perfect Sound 2.3. I friend gave me a copy of 2.0 to get started on
while I was waiting for 2.3 (2.0 is ugly, ugly code - a for loop for
timing the sampling rate!!!!!!). I don't know if the results are PD or
not. If you really want docs from them, you might try calling them and
seeing if they'll send the same to you (I haven't gotten anything yet,
so....).
In any case, I'm going to treat this code as "documentation", and write
something from scratch (I want to be able to issue cli commands that will
take a sample based on random criteria, so I can prototype stuff in ARexx).
That will _not_ contain any code from PS, and will be freely redistributable.
To get SunRize's phone number, try doing "type opt h" on a couple of the
samples in your sound sample collection. Chances are that some of them
have the SunRize phone number in them.
