export spectrogram as picture ?

hi,
I would like to know if there is a way to export fb2k's spectrogram viewer to a picture but in a very high resolution (for large printing) as a visual artist i like to play with pictures and i'm fascinated by the spectrogram view, I've converted some of my works to audio files but can't export the spectrogram's view 

thanks !

(sorry if I use wrongs terms I'm not audio pro ;) and french :p )

Spek will allow you to save its spectrogram as a PNG file. http://spek.cc/

i need something able to export at 9000x7000
SoX will not do this too. Maximal height is limited to 2050.
You can use ffmpeg.
Code: [Select]
ffmpeg.exe -i inputaudiofile -lavfi showspectrumpic=s=9000x8192:mode=separate outputfile.png
where 9000 is width and 8192 is height. Height must be power of 2, otherwise not all frequencies will be displayed. Color options are also available, see https://ffmpeg.org/ffmpeg-filters.html#showspectrumpic
