This tool will convert your audio files into spectrogram images. A spectrogram visualizes the amplitude of all frequencies over time. Brighter colors represent a higher amplitude and darker color represent a lower amplitude.
Select what width and height you want your image to be. Select from one of the presets or create your own custom size. The size can be up to 4000 pixels wide and 4000 pixels high.
A variety of color schemes are available for you to pick between. The presets are visualized so that you can get a feeling of what the spectrogram will end up looking like.
