The Vocal Remover for myRIO by Altenbach is a simple audio processing demo that runs entirely on the FPGA. This sample project processes audio data from the myRIO audio input, optionally removes the vocal track, and sends the remaining soundtrack to the audio output. The algorithm is simple: typical studio recordings have the vocal track centered (in other words, identical in the left and right channel) while all other tracks are not. Taking the difference between the two channels eliminates the vocal track while retaining all others.

Signal processing using an FPGA typically involves advanced code architectures and data transfer between the FPGA and a real-time target, making the resulting code difficult to understand for a beginner. This example demonstrates direct, single-point FPGA processing by using the power of LabVIEW FPGA to create a fully functional program within minutes. Once a student fully understands this, an instructor can expand the example for more advanced functionality.
