I've just downloaded REW and would first off like to say thank you to the developers of this tool for mking it freely available. It looks like an impressive program.

I ran it last week on my wifes PC, but had feedback loop problems with the Edirol UA3A interface I was using. So I got out my old Mac G4 powerbookand installed OS 10.4.8 and am back up and running. But I have run into an early problem callibrating the internal sound card.

I get this :

"Impulse peak is not where it should be, the measurement may have been corrupted. Check the Impulse Response and the Captured Data plots"

and

Sample rate: 44100Hz
-3dB points: 999.3Hz, 1.002kHz
Input device: No device selected
Input: No input selected
Channel: Left
Input volume: no control
Input RMS target: -5.0dB
Actual RMS at 1kHz: -41.2dB
Output device: No device selected
Output: No output selected
Sweep level: -5.0dB
20Hz .. 20kHz flatness: +12.2, -120.7dB
1kHz 2nd harmonic: 23.486%
1kHz 3rd harmonic: <0.001%

I have tried both Default Input Device and Mac OS X,CoreAudio,Audio ha...to no avail, as well as both left and right channels.

Anyone got any suggestions? Any help much appreciated.

Cheers,

Bevan
