Ariel Corp, Highland Park, New Jersey claims that the DM-N Ariel Digital Microphone is the world’s first to be based completely on digital electronics: the microphone’s proprietary technology, using two Motorola 56ADC chips, goes well beyond the capabilities of existing analogue-to-computer interfaces, the company claims, and the first version works exclusively with NeXT Inc’s NeXT Computer System, literally turning the system into a digital recording device for voice recognition (or does the company mean speech recognition?), music and data acquisition applications; the thing captures stereo analogue signals, such as speech or music, and then digitally encodes them for the computer to analyse, modify or store on disk; it’s $600.
