Real Time Feature Tracking

InFormant provides accurate pitch estimation and vocal tract resonance tracking, all happening in real time.

Powerful Spectrogram

InFormant directly overlays the estimated pitch and resonance on top of an adaptive scrolling spectrogram view.

Glottal Inverse Filtering

InFormant also includes an experimental real time glottal inverse filtering algorithm that tries to predict the source glottal flow signal from the input signal.
