Pitch Graph 1.0.3

Pitch Graph is a valuable tool for musicians aiming to tune instruments and refine intonation. It is designed to assist in practicing various instruments such as the violin, viola, cello, trumpet, and vocals.

The application constantly monitors the microphone, calculating frequencies up to 40 times per second, displaying them on a 3D accelerated graph. Offering a maximum detection sensitivity of a thousandth of a cent, it provides real-time feedback during instrumental play. The background blue lines represent note frequencies, with closer alignment indicating better intonation. Visual cues use red for sharp notes, orange for flat ones, and green for well-tuned pitches.

Automatically filtering intermittent noise and silence, the app ensures that sound and pitch information on the graph remain synchronized. Interactive features include tapping on the graph to produce corresponding sounds for easier interpretation. The replay function allows for session review by animating the graph while playing back the sound - beneficial for identifying areas needing improvement. Resetting the app with the clear button prepares it for the next take, and microphone control is conveniently managed by toggling the icon.

For optimal results, users are advised to consider certain limitations. Refresh rates may differ on older devices to enhance pitch detection performance. Detection is limited to one frequency at a time; hence, simultaneous bowing or strumming may give inaccurate readings. Background noise can affect pitch detection; therefore, quiet environments are recommended for best results. While tested with various instruments, individual variations can impact performance.

We trust that Pitch Graph will be of benefit to your musical pursuits.
