Capturing high resolution data causes MacBook to crash
« on: January 03, 2008, 01:24:47 PM »
I just purchased Signal Scope Pro and have used it to perform some acoustic measurements.  Everything works fine if I have the FFT size set to 512 and the sampling rate set to 44.1kHz.  When I set the FFT size any higher, my MacBook (orignial 2GHz white) crashes when I try to "save data".

It creates the file, but doesn't save any of the data.  At 512, it saves the data with no problems.

Are you running Tiger (10.4) or Leopard (10.5) on your MacBook?

How are the Guardbanding and Digital Anti-alias Filtering options set (in Preferences)?

Please try deleting your preferences file (~/Library/Preferences/com.faberacoustical.signalscopepro.plist). That appears to have solved a similar (perhaps identical) problem on a MacBook Pro.

I tried your suggestion of deleting the preference file and it seems to have worked.  It still crashes if I try to overwrite a previously saved data file, but if it's a unique file name, it saves no problem.

Thanks

Also for your reference, I am running OSX 10.5.1.  And I had the Guardbanding turned off.

Thanks
