## What is Chromatic Instrument Tuner?

Chromatic Instrument Tuner helps you tune your instrument. It uses advanced algorithms to discover the fundamental sound frequency. You can tune your piano, guitar, violin and other instruments, even your voice.

Features:
• Support and optimization for 64 bit processors
• Support for many instruments (guitar, violin, piano etc.)
• Visible from distance
• Option for non-standard frequency tuning (e.g. 443 Hz)
• Chromatic tuning (A, A#, B, C, C#, D, D#, E, F, F#, G, G#)

Instructions:
• Please make sure that there are no external noises and that your instrument is not too far from the microphone.
• Press the button to start the tuner.
• Play a note.
• The application will display the nearest note and the difference between that note and your sound.
• Tune the instrument and play again.

Advanced Options:
• If you need to tune to a non-standard frequency like many orchestra players (e.g. 443 Hz), please select that value using buttons located at the bottom of the screen.
