Sound Reference is a widget that calculates sound wavelengths for given frequencies and temperatures. It is a perfect reference tool for an audio engineer troubleshooting phase cancellation in multi-speaker loudsystems. It is also great reference for students.

• Functional knobs and dials (can change values by turning the knobs on the console directly)
• Calculates wavelengths of given frequencies for any room temperature
• Displays the frequency of musical pitches or MIDI note values
• Displays the music note closest to the given frequency
• Calculates the speed of sound in any temperature
• Converts between both metric and imperial units
• Displays the time/cycle of each frequency
• Calculates the length of different wave phases
• Saves your settings between uses
