An application for detects and displays the pitch of musical notes played on a musical instrument.

The aim of the project is the production of an application that a musician can use for tune his instruments.

This application use a Pitch Detection Algorithm (MPM algorithm See references), for identify the pitch of a sound recorded by the microphone. This implementation runs in real-time recording audio signal for a small delta of time and applaying the algorithm.

The User-Interface show to the user the nearest note calculated starting from the pitch identified.

The application provides a dialog box for set the user preferences, such as:

• the frequency of A4;
• the input device;
• the notation tu use for display the note.

Getting Started

A compiled version of the software can be installed downloading downloading the setup executable.

Deployment

Built With

The following libraries are used for the development of the application:

• Portaudio a free, cross-platform, open-source, audio I/O library;
• FFTW3 a C subroutine library for computing the discrete Fourier transform.
