The software is written from scratch using the Win API interface.

The audio stream is sampled using the WaveAddBuffer function in the Winmm.dll library.  I then pass the sample through a FFT to extract the frequencies and several custom filters; then render the spectrograph.  The samples also run through a custom loop buffer that records in ‘real’ time but only sends frames of data through a TCP pipe to the main application when called.  The callback and loop buffer keep the two applications synchronised.

It thunk... therefore it is!
