CentTune is a free guitar tuner for your DAW. Instead of a bare needle it shows a guitar headstock: click a key to pick its string, or let AUTO follow what you play. The string lights up in the colour of the reading, an arc meter on the neck shows how many cents are left, and the key tells you which way to tune. A string held in tune gets a tick; when the last one does, the whole guitar is in tune.

Features:
- Guitar mode with 16 tunings: E standard, Eb, D, C and B standard, Drop D down to Drop A, 7-string (B standard, Drop A, A standard), Open G, Open D and DADGAD.
- A headstock view, or a large meter with a button per string.
- Chromatic mode for anything else.
- Accurate to within a tenth of a cent across the guitar's range, steady on low and stiff strings.
- Reference A from 432 to 444 Hz, 440 by default.
- Mute switch like a tuner pedal; otherwise the guitar passes through unchanged, with no latency.
- An input light, and a hint when no audio arrives.
- Next to no CPU while the guitar is quiet. Resizable window.
- Validated with pluginval, Apple's auval and clap-validator.

Free: no account, no email, no iLok. From the makers of DropShift.
