808 / Note Tuner
Drop an 808, a sub-bass, a vocal note or any monophonic one-shot — get the note, the octave, and how many cents off it is. Tune your samples in one click.
01 · YIN algorithm
Cumulative mean normalized difference function (CMNDF) — beats raw autocorrelation by avoiding the classic octave errors on sub-bass.
02 · post-attack window
Skips the first 50 ms transient, then analyzes the loudest 200 ms region for a stable pitch reading.
03 · monophonic only
Works on single-note sounds: 808s, sub-bass, vocal notes, leads. Polyphonic material (chords, mixes) needs a different tool.
