text spectrograms?

["Philipp Schroeter" igelimstroh]

Hello list!
My question might sound somewhat exotic but it is something that
occupies my mind this morning.
While editing my recordings I sometimes do a bit of equalization. And I
am still not satisfied with it. I am blind and not able to view the
spectrogram of a sound file. That's why I have to adjust frequencies by
trial and error method. That's fine for High pass filtering but it is
not practicable for subtle tasks. That is why I am wondering if there is
any way of exporting/converting a spectrogram into a concise text file
so that I have a clear overview of the prominent developments of
frequencies?
I would be glad if there is a chance, please let me know!
best regards from Germany
Philipp
