Software Review: Cognicity AudioKey 1.0 (Part 4)

There seemed to be one catch, though. When I did a digital extraction of the track from CD, I found a serious Rice Krispie problem (snaps, crackles, and pops). I scratched my head for quite a while over this one, then recorded the original track (without the embedded message) to CD and extracted it, and it had the same problem! Luckily, I was able to track this down to the digital extraction program that came with my CD-R drive, because another program (CDex, which is not only wonderful, but free) worked fine (I say luckily because it could have been the CD burning program that caused the pops!). So AudioKey had nothing to do with the noise. But I wasn't quite finished. No, if this review was going to deserve the name "torture test", AudioKey was really going to have to sweat for it. This time I took the track that I had brought in via analog and converted it to Microsoft's Windows Media 4.0 format, which Cognicity has no support for whatever, since the format is so new. I used the 64 Kbps setting, which definitely changes the sound (no easy CD transparency for this test!). Since there are no programs yet which convert Windows Media to WAV, I simply re-recorded it via the sound card, converting from digital to analog to digital again. And AudioKey still read the message.
