Find Musical Pitch from Frequency in LabVIEW

[Roohcifer]

Overview

This example takes a frequency as its input and identifies the corresponding musical pitch class, octave, and pitch.

Description

In its current form, the code finds the 12-tone equal temperament pitch, though it can be easily modified to accommodate any other well-tempered tuning, such as quarter-tone tuning or any other tuning based on an equal subdivision of the octave.

Requirements

• LabVIEW 2012 (or compatible).

Steps to Implement or Execute Code

1. Enter the fundamental frequency of the tone that you wish to classify
2. Run the program.
3. The program will return the pitch, along with additional details such as Pitch Number, Class and Octave.
