The processing pipeline consists of:
1. Specific channel extraction and decimation with help of digital down conversion.
2. FM Demodulation
3. Further down sampling and filtering for audio playback.
In-between the software displays data from intermediate stages of processing pipeline:
1. Spectrum and waterfall spectrogram of input signal at 40MHz
2. Spectrum after digital down conversion at 800kHz
3. Spectrum of demodulated signal at 800kHz
4. Final audio signal and its spectrum.
