Hello, still loving AudioMulch, it's a very inspiring tool!
I'm running AM 2.2.3 on a 2012 MacBook Pro, OSX 10.8.2. Last night while recording to a 24 bit stereo AIF on my external Lacie FireWire drive I got an error message after a couple hours and it stopped recording. At first I thought it was a cable/drive error but when I checked the file today I saw it was just over 2GB. Is this a 32 bit limitation? I checked AM help files on SoundOut and File Recorder, didn't see anything. If that's not the case I can probably dig up a log.
