- ***************************************************
- Our Research Lab has a few questions concerning the
- SPARCstation 10's audio capabilities ...
-
- We do a lot of NSF and NIH research on speech
- synthesis and currently use an ATT DSP32C VME board
- and ESPS software (plus a lot of custom C stuff).
-

-
- If you respond, please reply directly to:
- white@drwho.ee.ufl.edu
- and we will post results.
- Thank you very much !

- **************************************************
- Our questions concerning the 10:
- **************************************************
-
- 1) stereo or mono ?
- 2) which A/D and D/A chip(s)?
- 3) native data format(s):
- a) 8-bit u-law (like our IPX's, ELC's, etc.) ?
- b) 16-bit linear (PCM) ?
- c) other ?
-
- (I realize you can convert _some_ formats
- to others via simple filters)
-
- 3.5) supported sampling rate(s)? (yes, I know
- we can also convert fs with filters)
-
- 4) How is the background (idle) noise? We ask this
- because our ELC's and IPX's have audible background
- interference, apparently associated with bad
- shielding or grounding (i.e. no separate converter
- ground). All of them do it, we use headphones a lot
- and are critical listeners ...
-
- 5) anything else we should know ?
-
- ***************************************************
-
- We're real close to buying one, so if there's anything
- you think we should know, please contact us directly.
- And again, thanks.
