Problems calibrating soundcard Edirol in Macos

[jeancoum]

Here's another Mac Newb from The Netherlands. Just started, in REW and in this forum, both of which are great, I think. I want my room optimized (hard surfaces, loads of echoes etc) with sound absorbers and diffusers. This app should be the killer for me!!
The app appears to run fine, but I can't get past the first hurdle: calibrating my soundcard Edirol UA-3d (which normally works fine in both playback I-Tunes and in recording albums). When I open the Settings-window to calibrate the soundcard, and click the Measure-button, I get a pop-up, that titles 'Unable to take SPL reading' with the following message: 'SPL meter audio input not available. This has probably to do with the strange message at start-up: 'No input mixers available supporting PCM-SIGNED 48000.0Hz, 16 bit, stereo, 4bytes/frame, little endian'. I can bypass this message and REW starts fine.
Sample rate is at 48, and not at the advised 44,1, because the app crashes if I try to change it. Input channel is Right, so my loop goes from line-out right to line-in right. Output device is Default device, and it is properly selected (from what I can tell) in my system preferences. Java 5, Macos 10.4.8
Please help.

You are a bit scuppered, unfortunately, unless you can use the on-board audio. Apple's Java virtual machine doesn't provide any access to audio inputs other than the on-board input and gets very upset if you try 48k instead of 44.1k. Leopard has, i'm told, sorted out at least the inability to access other audio input devices but I don't know whether it solves the 48k problem. There are also a range of rendering and component size problems under OS X with the current build of REW, but I have sorted those out in the next build which is being beta tested at the moment.

Thx John,
Glad it's not me wasting anyones (your) time because I'm a cluts, didn't read the manual properly or made some stupid mistakes.
I'll just wait for my Macbook with Leopard to return after a minor repair (expected on monday) and try again. Hopefully I'll be succesfull, otherwise I'll try the onboard sound. In both cases, I'll report back (also for future references).
Otherwise, you've done a great job sofar. Good luck on the development.
Grz, Jean
