Hello,
Thank you for contacting National Instruments.
The NI PCI-6013 is capable of acquiring sound signals that are converted into voltages via an appropriate microphone. Are you asking whether or not your VRS Telephone Recording software is compatible with the PCI-6013? If you can provide a little more information about the system you are trying to build, I will be happy to offer any suggestions I can.
