Hopefully this helps 1. I looked at the user manual, and you should be able to loop the RCA out to the RCA aux/in. And in fact, I think you could even loop it using the optical, as it has both Spdif in/out. 2. These SCs' are driven by complex software that allows changes to audio characteristics typical for gaming - I had to go into my SC software where I had to configure it so that it doesn't change the audio and also I could set the aux-in level. I saw in the AE-9 manual settings to switch off the acoustic engine or DIRECT MODE. 3. I read from the manual AUDIO RECORDING MICROPHONE AND OTHER INPUT TAB The Microphone tab offers users the ability to configure microphone input with various controls and CrystalVoice technology while the Other Input tab allows users to choose between recording devices e.g. AUX-in / Line-in, Digital (SPDIF-in) and What U Hear 4. The AE-9 looks like a serious piece of kit - no reason why you shouldn't be getting close to their spec 0.0001% by looping OUT to IN. 5. ARTA is actually very simple to get going, which is why I use it more than anything else and is very accurate. only 3 steps are needed (its obviously has more rich features) a. - Select "Spectrum analyser" b. Setup Audio device c. Press play. From what I can see on the clips. - There is not enough volume or input level is to low. You should aim for the 1khz signal to peak around -3db. - The noise floor level should be quite flat across all freq except for the harmonics- check that the AE-9 is not applying software filters etc that is boosting/cutting some frequencies - Try get the Arta working with the sound card by looping OUT to IN as a baseline before adding other devices
