When the program starts, it begins producing a spectrogram with a range of 0 Hz to 2500 Hz. The frequency axis will have axis ticks with labels. The maximum frequency will be displayed on the TFT. The pixels will be colored according to the log of the magnitude of the FFT output.

A spectrogram is a detailed view of audio, able to represent time, frequency, and amplitude all on one graph. A spectrogram can visually reveal broadband, electrical, or intermittent noise in audio, and can allow you to easily isolate those audio problems by sight.

A spectrogram is a representation of frequency over time with the addition of amplitude as a third dimension, denoting the intensity or volume of the signal at a frequency and a time. Why a Spectrogram?

Basics - The Frequency Spectrogram View. The frequency spectrogram view allows you to view the mix of sound frequencies in an audio file. When enabled it appears beneath the waveform. Its horizontal axis represents time, just as the waveform does, but its vertical axis represents sound frequency, with low frequencies at the bottom and high frequencies at the top.

The spectrum analyzer above gives us a graph of all the frequencies that are present in a sound recording at a given time. The resulting graph is known as a spectrogram. The darker areas are those where the frequencies have very low intensities, and the orange and yellow areas represent frequencies that have high intensities in the sound.
Spectrogram - Wikipedia
https://en.wikipedia.org/wiki/Spectrogram
A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called waterfall displays. Spectrograms are used extensively in the fields of music, linguistics, sonar, …

In a spectrogram representation plot — one axis represents the time, the second axis represents frequencies and the colors represent magnitude (amplitude) of the observed frequency at a particular time. The following screenshot represents the spectrogram of the same audio signal we discussed earlier. Bright colors represent strong frequencies.

So here we have four visible harmonics : the frequency of the first one is about 1kHz, the second about 2.3kHz, the third one 3.5kHz and the fourth one at about 4.7kHz (we guess there is also a very faint fifth one, about 5.9 khZ) Fundamental frequency and harmonics 3.3 Sonic texture Sonic texture describes the patterns occurring in bird songs.
