Features

These features might change over time and I am not sure if this list will always be up to date.

• Detect pitch based on autocorrelation and FFT spectrum
• Accuracy improvement by evaluating the spectrum phase information and polynomial fitting
• Show how pitch changes over time
• Tuning to equal temperament
• Settings for choosing concert pitch, FFT window size, FFT window type, overlap and more.
