Talk:Covox Speech Thing

Other Covox products
Covox produced two 8bit ISA bus sound cards. The Sound Master and the Sound Master II. The Sound Master sported a pair of digital joystick ports for Atari 2600 compatable sticks. I don't recall what audio devices it had onboard other than the Speech Thing.

Article on the Sound Master II. http://www.atarimagazines.com/compute/issue142/112_Sound_Master_II.php Jumper info, http://artofhacking.com/th99/i/C-D/50374.htm

The Sound Master II incorporated the Speech Thing and AdLib onboard (with a YM3812 chip), a MIDI port (but no joystick port), and with a 80386 CPU and software driver could emulate a Soundblaster. Using the Speech Thing disabled access to any parallel port using the same interrupt. I think there was also another, Covox proprietary, audio device on the Sound Master II. It's been years since I had the two versions of these cards and information is very sparse online.

Bio. of Kevin O. Corson, part of the Covox team. http://www.marketingengineers.com/history.html Perhaps he might remember or have some more information?

The Sound Master II gained enough game support that Media Vision incorporated 100% emulation of it on their 'ultimate' soundcard, the ProZonic.

Software for Covox
Is there any MP3 player that supports this gadget? It would be nice to create a list of software that supports Covox. I reanimated a very old laptop for nostalgy purposes that has no sound card, so I'll soon become a Covox user - in 2008 :D —Preceding unsigned comment added by 85.181.65.149 (talk) 20:36, 14 April 2008 (UTC)


 * Well I remember seeing some old DOS players that supported it (and the internal squeaker) back in the day, but didn't make a great deal of use / pay much attention to them as my 486 was extremely marginal CPU-cycle-wise for playing back at any kind of good quality (by the time I had a good CPU, there were decent windows players). I think something like 123MPG? And there was a slightly more graphical general-purpose fullscreen media player (did mods, midis etc as well) that supported them. The name escapes me, but there can't be THAT many of 'em if you google with suitable terms :) 193.63.174.11 (talk) 11:54, 2 March 2011 (UTC)

Sound Master II Drivers Available from Covox Tympanum View products that this article applies to. Article ID	:	88153 Last Review	:	October 14, 2003 Revision	:	2.0 This article was previously published under Q88153 SUMMARY Sound Master II, manufactured by Covox Tympanum Corporation, emulates an Adlib Musical Instrument Digital Interface (MIDI) card. Windows 3.1 digitized sound drivers for the Sound Master II card are available through the Covox BBS numbers listed below. MORE INFORMATION Although the Sound Master II is compatible with the Adlib MIDI card, the MIDI port on the card needs specific Covox drivers for MIDI support under Windows 3.1. Covox is currently developing these drivers and they will be available on the Covox BBS when they are completed.

The Covox BBS also includes an updated Wave form audio driver dated July 10, 1992. If you have a Covox sound device and use Windows 3.1, Covox recommends obtaining the newest wave form driver.

For additional information, contact Covox technical support or download the file WINHELP.TXT (from the Covox BBS), which provides information on installing Covox drivers for Windows 3.1.

The products included here, Sound Master II and Adlib MIDI card, are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability. —Preceding unsigned comment added by Bizzybody (talk • contribs) 03:49, 5 June 2008 (UTC)

Disney Sound Source
The article is somewhat misleading claiming that Disney Sound Source (from here just DSS) compatible software can be used with simple covox plugs. While the article is correct that both devices incorporate simple digital to analog converters, the DSS features an additional 16-sample buffer with an additional pin going back to the LPT port which is used by most software to detect if the DSS is connected and operational. Popular examples for this are Wolfenstein 3D and Niteraid. An example of this detection routine can be found in the "programmers guide" which is available here http://www.leeland.net/disoso.html

Maybe this article can be split up some more, considering there are various "covox"-style adapters available (Speech Thing, Sound Master, JDAC, Sound Player, Soundrive, Disney Sound Source) which all incorporate converting signals from the LPT port to analog sounds (with exception of the Sound Master which is an 8bit ISA-card), but all have a different feature-set and functionality. To my knowledge the name "Covox" originally refered to a company in Oregon, USA which built the Speech Thing, Sound Master, etc. Another Option would be renaming this article to LPT-DAC and getting referenced from the searchphrase covox, as covox is the commonly used "trivial-name" for such adapters.

I'd do this myself, but I'm not a very good writer. If you need any more info and/or sources, let me know as I'll check this talk page for updates.

Sample rates
The Covox and printer port definitely supported far higher samples rates than mentioned in this article. I used one in the early 1990s to generate an AM carrier wave to broadcast music on AM, and with optimized assembly code on a 16 MHz 80286 I could reach a carrier frequency of 200 kHz, meaning a sample rate of 400 kHz. When using timer interrupts I suppose much lower frequencies would have been achievable. — Preceding unsigned comment added by 82.168.39.55 (talk) 00:17, 24 December 2012 (UTC)

Covox Voice Master
I have removed the Covox Voice Master from the list of commercial products, since it was not a PC peripheral, but one for 8-bit Ataris. Besides, it seems to have recorded sound as well, for speech recognition software. Unfortunately there is very little information to be found, but to list it as a variant of the Speech Thing is definitely misleading.—Austriacus (talk) 11:46, 19 May 2013 (UTC)
