Spectrograms
  • is a visual representation of the spectrum of frequencies of a signal as it varies with time
  • when applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams
  • when the data are represented in a 3D plot they may be called waterfall displays
