Software Oscilloscopes

[marec]

I'm developing a (slight) curiosity about panel resonance.
I've got a mac on panther, (ruling out fuzz whatsits) and a PC on XP. Are there any favoured freeware / shareware / cheap (storage) oscilloscope programs?
How might I measure panel vibration. My days of ceramic cartridges are long gone, but that might be cheaper than another transducer.
Any ideas please?

I am not sure you need an oscilloscope to measure panel resonances. A spectrum analyzer and other tools included in the ARTA speaker measurement software might do OK.
What you probably do need however is an accelerometer instead of a microphone. Do not know where to find.

Hi Svein_b
Many thanks
I've had a quick look and this looks fine, apart that is from the £50 premium! I think that a ceramic phono cartridge may work here and it (at the moment) is top of my list...

Hi,
many of the ceramic cartridges were for mono only and did not respond to vertical modulation.
This may make a stereo cartridge wired for the vertical direction (stereo difference signal) compulsory.

The ARTA software free download is fully functional (only lacking the possibility to store raw data for later analysis).

Hi Svein_B

Thanks for persisting. I use a windows laptop, so have not been sure how to approach supported soundcards. However, I have now ordered an x-fi usb card & hope this will do the trick. I'm still trying to source an accelerometer.

This is all new to me and i hope to get plenty of entertainment from it....
