Reson8

Reson8 is a studio-grade strobe tuner with a native C++ engine that measures
to a tenth of a cent.

• Strobe gauge, constant-Q spectrum and intonation-drift analysis
• Guitar, bass and ukulele, including polyphonic strum detection
• Brass and woodwinds, drums, and the full professional piano suite with

measured inharmonicity and Railsback curves

• Configurable reference pitch and historical temperaments

Everything runs on your machine. Reson8 has no network access at all: audio
from the microphone is analysed on-device and never leaves it, there is no
account, no telemetry and no tracking of any kind. The complete app,
including the professional piano suite that is a paid unlock on phones, is
free on Linux.

Microphone capture needs the audio-record interface. If it is not connected
automatically, run:
