Most of the audio editors are able to show us different kinds of audio analysis like this:

enter image description here

  • Wave form (whole file);
  • spectral frequency (whole file);
  • spectrum analysis (for a slice).

The generated images can be saved one way or another.

Is there a command line alternative to do this?

Windows 7. A multi-OS solution is preferred.

One of three tasks could be performed with SoX:

sox file.wav -n spectrogram

I ended up using for %w in (*.wav) do ("p:\sox-14-4-2\sox.exe" "%w" -n spectrogram -o "%~nw.png" -r -m -y 130) - (where the sox.exe is obviously pointing at the right one) – twobob 2 days ago

Imagemagick would be the solution, but the screen capture does not seem to work in Windows (it's looking for an X server).

Refer to the answers to this similar question here for other options.
