- From PC Sources, August 1992, reprinted w/o permission (although I'm
- sure they'd be flattered since my r-w/o-p's have generated half a
- dozen requests for subscription information :)
-
- There's no reason to leave sound in the office if you have a laptop
- that can handle Windows 3.1. Parallel port adapters from Media Vision,
- M.P Technologies, Video Associates Lab, and VocalTec give any PC -
- desktop or laptop - the ability to record and play back 8-bit monaural
- sound. All three adapters come with Windows 3.1 drivers and utilities
- that let you use sound with your Windows applications.
-
- Media Vision's 2- by 5-inch Audioport runs on four AAA batteries
- or the supplied AC adapter. It has a small internal speaker audible
- only in quiet environment,s and two jacks: one for a mike, and the
- other for an amplified speaker or headphones. A thumbwheel adjusts
- output volume. There is no pass-through connector for sharing the
- parallel port with a printer. The Audioport also provies an 11-voice
- FM synthesizer (YM3812) for games and educational software. Sound
- quality isn't as good as that from an internal sound board, but it's
- transportable. A new product listing at $199, Audioport will sell
- for less from direct vendors.
-
- M.P. Technologies' $179 Sound Board product is actually two adapters
- that share one parallel port. One adapter contains a built-in microphone
- along with input and output jacks. The other adapter, available
- separately for $79 as Sound Booster, provides a jack for an external
- speaker. It has a pass through connector that lets you attach a
- printer or the recording adapter. Both packages come with a small,
- amplified speaker, and neither requires batteries or external power.
- They're available direct from M.P. Technologies (800-292-1577 x3781)
-
- Video Associates Lab's Microkey AudioPort, an external digital adapter,
- connects to a parallel port. It measure 2.25 inches by 3.75 inches,and
- comes in two models - the Microkey/AudioPort Record and Play that sells
- for $295, and the Microkey/Audiport Player that sells for $195.
-
- VocalTec's $179 compact audio technology (CAT) plugs into a parallel
- port, and is powered by a 9-volt battery or an adapter included with the
- product. CAT is capable of a higher-quality sound, since it has a very
- low signal-to-noise ratio (CAT can play at a dynamic range of 72dB).
- As a result, CAT promotes itself as being more economical in drvie space,
- since you can record voice messages at a lower sampling rate, while
- maintaining good sound quality.
-
- No additional phone numbers or addresses were given. No additional
- information about SB or Adlib compatibility was given. If you find
- out more info, by all means POST!
