Entropy-Piano-Tuner1.3.0

Record every key of a piano, calculate an instrument-specific tuning, and apply the result with the integrated tuner. Entropy-Piano-Tuner solves the problem of tuning a piano according to its actual acoustic behavior rather than relying on a generic preset. Its method minimizes entropy while taking the individual characteristics of the instrument into account.

The workflow has three stages: capture recordings from all keys, let the software compute the optimal tuning automatically, and use the built-in tuner while adjusting the piano. This makes it useful to piano technicians and experienced players who want a tuning tailored to a particular instrument. It can support tuning work during maintenance, restoration, or preparation for performance when the piano’s own response needs to be measured.

The program runs on Linux and is open-source software. Piano tuning requires sophisticated skills, so users should read the remarks on the help pages before beginning the tuning process.
