I used an in-line mic on my IEM and talked from 20 cm while tapping on the table about 10 cm away from it, again simulating keyboard sound of some sort. With such a steady state signal, it should not do this. I saw this in my earlier instrumentation where levels were dancing up and down constantly if I had the unit active.
Second, the peak levels are modulating up and down. This may impact the target market of gamers. There are two issues though: one is pretty high level of latency that is close to 0.2 seconds. Then when the burst times, it it is let through.
Turning on the mode with high settings, gives us the expected results: the gap in between is recognized as being continuously the same so it is heavily muted. Not sure what is up with that but it was repeatable. One strange thing in bypass mode in blue is that the device seems to start with high noise floor and then goes back down after a couple of seconds. It seemed to accept up to about 4 volts above which it got severely distorted so I went with that as that is the closes to 0 dBFS input: Testing here has two parts: standard measurements for any audio interface and then objective and subjective testing of the noise cancellation logic.Īt first I could not figure what the adapter is doing with respect to input voltage. I eventually figured out that you have to extract the files yourself and then run setup after which it finished in an instant with no message. It ran but would get stuck at 0% progress. Upon downloading I ran setup out of the zip folder. For instrumentation, I built an adapter for 4-bit 3.5 mm that it accepts to the balanced output of my Audio Precision analyzer.Īsus provides a control app for this device. Anyway, I used an in-line mic from my IEM for voice testing. I had a hell of a time finding out what type of microphone as it is not documented in the horrible "manual." I put "manual" in quotation because it is one of those fold out jobs with 20 languages simultaneously in every section! Worse yet, it tells you absolutely nothing about the device. But unlike those devices, it also has an analog to digital converter with ability to perform "AI based" noise cancellation to your microphone.
