About Tuner
Tuner is a basic tuning app whose project is hosted on Codeberg. It detects pitch using autocorrelation and FFT spectrum analysis, and refines accuracy by evaluating spectrum phase information and polynomial fitting. It displays how pitch changes over time and tunes to equal temperament, with settings for concert pitch, FFT window size, FFT window type, overlap and more. The project is licensed under GPLv3, and translations are handled at translate.codeberg.org. The README notes that the feature list may change over time and may not always be up to date.
