This is a basic tuner app.
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.
