Write a Protothreads C program which will: 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. The colorization scheme is up to you, though the …

Create an audio spectrogram A spectrogram is a visual representation of the spectrum of frequencies in a sound or other signal as they vary with time or some other variable. Spectrograms are sometimes called spectral waterfalls, voiceprints, or voicegrams. Spectrgrams can contain images as shown by the example above from Aphex Twin. recent stuff
Spectrogram View - Audacity Manual
https://manual.audacityteam.org/man/spectrogram_view.html
The Spectrogram View of an audio track provides a visual indication of how the energy in different frequency bands changes over time. The Spectrogram can show sudden onset of a sound, so it can often be easier to see clicks and other glitches or to line up beats in this view rather than in one of the waveform views.
