Spectrogram

Spectrogram[list] plots the spectrogram of list.

• Spectrogram[list, n] uses partitions of length n.
• Spectrogram[list, n, d] uses partitions with offset d.
• Spectrogram[list, n, d, wfun] applies a smoothing window wfun to each partition.
• Spectrogram[list, n, d, wfun, m] pads partitions with zeros to length m prior to the computation of the transform.
• Spectrogram[audio, ...] plots the spectrogram of audio.
• Spectrogram[video] plots the spectrogram of the first audio track in video.
