| The sound digitizer sounds interesting.

| I am also interested in the sound digitizer, provided it has at least
12 bits of resolution per sample. All the digitizers I have seen for
the Amiga either don't say how many bits they use, or admit to being
only 8 bits wide.

| Another aspect of data acquisition !!
Could it be possible to build a frame grabber that could also be
use as a sound grabber ?
To capture images at low cost would be an eventual goal of mine!
Can a technical person comment on that mixed hardware project ?

| I'd love the sound digitizer!!
re:.2 Doesn't the Amiga sound chip play only 8-bit samples?

| 2347.5 | I want a sound digitizer | GUCCI::HERB | | Wed Mar 15 1989 09:25 | 5 |
| Do those sound digitizers that cost 70$ come with everything you
need?

| 2347.6 | Amiga = 8, TV = 12, CD = 16 | SAUTER::SAUTER | John Sauter | Wed Mar 15 1989 10:18 | 6 |
| re: .4---Yes, the Amiga sound output is only 8 bits wide. That's why
musical instruments sound so muddy. 8 bits is OK for sound effects,
and barely adequate for speach, but completely inadequate for good
music. 12 bits provides sound as good as a TV set, but audiophiles
want 16 bits for "really good" music.

| 2347.7 | 16 BIT COULD BE POSSIBLE | FRAIS5::ISTURM | | Fri Mar 31 1989 08:39 | 16 |
| WHILE BUSY AND OUT FOR TRAINING AND HOLIDAYS , I 'D LIKE TO DELAY
THE OTHER HW STUFF TO SOMEWHAT IN APRIL..
READING AND THINKING ABOUT THE 8/12/16 BIT A/D CONVERSION FOR BETTER
SOUND , IT SHOULD BE POSSIBLE TO CREATE A 12 OR 16 BIT ONE FOR THE
AMI.
AS FAR AS I AM NOW , I DONT SEE ANY HARDWARE PROBLEM , BUT THE SW
HAS TO DO IT.
SO IF WE CONNECT A 16 BIT A/D TO PARALLEL PORT , WE HAVE TO TAKE
2 TIMES AN 8 BIT PART OF THE SAMPLE , SO I'M NOT SURE ABOUT THE
FREQUENCY RANGE WE CAN COVER.
WELL , T TRY TO PUT AN HW EXAMPLE UP TO THIS NOTESFILE DURING END
OF APRIL.
REGARDS , INGO

| 2347.8 | why 16 bits? | AITG::WISNER | Paul Wisner, ...I have a totally traditional haircut... | Fri Mar 31 1989 16:21 | 3 |
| Am I missing something? What would be the purpose of
recording 16 bit samples if they have to be played by
8 bit sound hardware??

| 2347.9 | I want a 16-bit DMA stereo sound board | BARDIC::RAVAN | | Fri Mar 31 1989 22:26 | 17 |

Well, what I would like to see is a 16-bit A/D, and at least
2 16-but D/As that were DMA so I could output 44.1K samples/sec * 2 channels.
At least. And I'd also like it to be able to read a SCSI disk protocol
directly so that I could simply tell the board to read samples directly from
my disk and not bother using bandwidth on the system bus. And finally, this
should be available at least as a 2000 board.
Using the parallel port is not feasible for input bandwiths like this, e.g.,
44.1 * 2 * 2 Kbytes/sec, since it is only capable of speeds usable by the 6800
PIA-like stuff. There are slow timing restrictions, at least from what I
understand from my more hardware-oriented friends.

| I too would be very interested in a frame grabber or video digitizer.
In addition, I should think a reasonable genlock would be feasible
given the current video chips available.
