I have found a 2-channel, USB-powered, ICP® sensor signal conditioner with USB digital output (24-bit A/D). It is supposed to provide me with a digital output that I should be capable to read from my computer. What software could provide me with a row data output file such as .wav?
The datasheet says that's a usb audio device, so any audio software can give you a .WAV.
You could buy another usb sound card for a few dollars. Consider carefully if you need to spend $1000 for that device.
Edit: Although it does +/-10V output, so that probably explains the higher cost.
