This is an extension of the real time FFT demo provided with the data acquisition toolbox (demoai_fft). It adds digital third octave filtering to the incoming data stream.
Works with any analog input source from the Data Acquisition Toolbox.

This uses a few files from the Octave Toolbox, with slight modifications and additions. The necessary files are included in this download, but you should get the original (see Contributing Files, below).
