how to get spectrum data's without playing an audio file?

[victorvictor]

Hello

I would like to use the spectrum element to get the spectrum data of an audio file without playing it. For example, I would like to get the spectrum data's of every second of a  'flac' file, but as fast as possible, not by waiting that the piece is completely played to the end.

Please how could I do that?

Not completely sure about this, but if the spectrum element actually has
to have a sink then try fakesink.  Fakesink should suck your file through
your pipeline at max speed.
