audioprism is a spectrogram tool for PulseAudio and WAV files.
In real-time mode, audioprism renders the spectrogram of a PulseAudio input source to an SDL window. The pavucontrol mixer can be used to select the audio input source. PulseAudio provides loopback “monitors” of audio outputs as audio input sources, so audioprism can be used with audio streams playing from another program.
In WAV file mode, audioprism renders the spectrogram of a WAV file to an image file. The output file can be any kind of image format supported by GraphicsMagick, determined by its file extension.
