spectrogram~

With support for multiple window functions, perceptual frequency scales (Lin, Log, Mel, Bark, ERB), customizable color schemes, and mouse-driven zoom, spectrogram~ provides flexible visual feedback and real-time control for spectral analysis, sound design, and interactive audio applications.

The spectrogram.colorbar object displays magnitude-to-color mappings for an attached [spectrogram~] object.

The spectrogram.bandpass abstraction performs a frequency domain bandpass that can be controlled by the spectrogram~ object.
