Spectrograph of Audible Frequencies
Spectrograph of Audible Frequencies is a software for visualization of the main musical notes.
The graph consists of two parts. The upper part displays the spectrum of audible frequencies (from 20 to 10000 Hz) divided in three parts: low (blue), mid (green) and high (violet) range frequencies. The most intense sounds are highlighted with a bigger color opacity. The lower part shows the average volume intensities (from -50 to 50 dB) by frequency range.
