TUNER

Controls

• Reference A4415 to 466 Hz — The pitch of A4 the notes are named from, 415 to 466 Hz (440 standard, 415 baroque, 442 many orchestras).
• DisplayNeedle / Strobe — Needle: a bar from -50 to +50 cents. Strobe: three bands that stand still in tune and move right when sharp, left when flat, faster the further off.
• InputStereo / Left / Right — What is tuned: both channels summed, or only the left or right input.
• OutputThru / Mute — Thru passes the audio; Mute silences it, for tuning on stage.

Properties

YIN pitch detection: the input low passed and taken down to 22 to 24 kHz, analysed about 47 times a second over the last 1024 + up to 960 samples (FFT autocorrelation, cumulative mean normalised difference, first dip below 0.15), refined by parabolas on the difference function at 1, 2, 4, 8 ... periods; within 0.25 cent from 27 Hz to 4.2 kHz on test tones. 25 Hz to about 4.5 kHz; below -70 dBFS RMS counts as silence, and the last note holds for half a second. Readings within 50 cents glide. No latency, no Rack module.
