The spectrogram's whole-buffer short-time Fourier transform, forwarded from @maruaudio/audio-sdk/analysis: the canonical radix-2 FFT, paired stereo transform, a Hann-windowed whole-buffer magnitude spectrogram in dB, and a planar-to-mono down-mix. Pure functions over typed arrays — no canvas, no DOM — so an entire clip's time × frequency grid can be computed and tested headlessly.
