I dictated the previous message using iListen on 500mhz G3 PowerBook running OS 10.2.3 with a ANC-650 microphone and an Andrea USB pod. It also works using analog input with a Griffin Pre-amp. I found the microphone signal for my ANC microphone to be much stronger on Jaguar, where I can turn up the input level on the Sound system preferences panel. I won't claim to be getting high accuracy though, just that it's functional for me. Joe Senecal
