Thanks David. I got the measurement data also. That plot shows what I suspected, and it will not be easily correctible. The data from the line input is massively overscaled, repeatedly wrapping around - it is likely that the byte ordering of the audio samples is wrong and the samples are being fed to REW as big-endian rather than little-endian, even though REW requests a little-endian input stream and the soundcard debug data shows little-endian as supported. I suspect this problem may afflict many of the PowerPC-based Macs. I can look at modifying REW to process big-endian data in a future build, but short-term there is nothing I can do to correct that problem. The Line In application may help, as it provides an additional software buffering layer in the audio data path which may corrrectly pass data to REW in the requested format.

I am not that computer savy, so I realy don't understand the technical parts of your answer. Your answer is probably why REW would not work on my ibook g4 using the M-Audio Firewire Solo, as that computer is not an intel based machine. I wonder if the users who got REW to work on an imac have intel based imacs? Of course, if I had an intel based imac I could run windows anyway! If you can get REW running for non-intel based macs, that would be fantastic. I’ll play with the line-in program, and if I get it to work I’ll post my settings.
Thanks for your work on this.
