A video from NIWeek 2008. Benjamin Cook really had fun building this electric guitar effects system based around NI hardware and LabVIEW.
This is a wireless audio processing project. A 550 MHz transmitter transmits FM modulated data to a 5600 down converter. It down converts the data to 25MHz. That gets sent to a 5640R IF-RIO card. The IF-RIO card has an FPGA. That’s where all the demodulation and audio processing happens which then gets sent out the sound card. You get very low latency audio response.
