We are trying to measure the sound of an aircraft by driving a microphone-equiped van along with the aircraft on the run way. We'll then store the data on datasocket server so that we can display the data in real-time on the web. My question is what's the best tool (hardware and software) for this application? Thanks.
My own recommendation would be to use LabVIEW as your software. LabVIEW makes DataSocket binding as easy as right-clicking on a front panel object. If you are more comfortable programming in a text-based environment, then ComponentWorks would be my next recommendation.
There have been many applications where individuals just use their PC's sound card to record sound using built-in sound recording and signal processing inside LabVIEW. However, for cleaner sound processing, I'd suggest you take a look at National Instrument's DSA boards (NI 4551 and NI 4552). Check out their specs at http://www.ni.com/catalog.
