    Free software with GUI where modifying spectrogram modifies sound ?


    I've seen free software which does that, but can't recall where.

    You modify the spectrogram, à la photo-shop , and the sound is changed accordingly,
    e.g. erasing part of the spectrogram image removes some of the sound spectrum, etc.

    Any software suggestions ?

    Well, the real one is iZotope's Iris synthesizer. It's a great deal of fun, but definitely not free (retails for around US $200).

    https://www.izotope.com/en/products/effects-instruments/iris/

    One interesting freebie that allows you to play with the spectrogram of a WAV file is called Virtual ANS by WarmPlace.Ru.

    http://warmplace.ru/soft/ans/

    He has a number of curious little software oddities that focus on audio-visual experimentation. Check out PixiVisor and PhonoPaper as well as Virtual ANS.

    There is another free VST that had similar features a while back. I will try to dig it up.

    Thanks for that link , "Virtual ANS" on the face of it looks ideal, (and better than the similar software I vaguely remember) , however everything that's been through "Virtual ANS" sounds vocoded , whether you like it or not , see ... http://www.freesound.org/people/Timbre/sounds/250529/

    I shouldn't look a gift horse in the mouth : "Virtual ANS" it's a very interesting tool for making electronic sounds.

    I have not tried this one out because it requires a little more setup than a simple .exe file, but it appears to behave similarly to your proposal "modify the spectrogram, à la photo-shop , and the sound is changed accordingly,e.g. erasing part of the spectrogram image removes some of the sound spectrum, etc."

    Also, there is a KVR discussion regarding these and other similar free software:

    Seems like Adobe Audition added graphical sonogram editing several revs back, didn't it? And Sony has a relatively recent product that is focused primarily on spectral manipulation of varying types ("SpectraLayers" -- look it up). [EDIT: Oh sorry, the original post asks about "free".]

    Hi Timbre

    If you are looking for something in VST format, try this.
    I have used it to clean up sounds and for creative purposes with good effect:
    http://www.stillwellaudio.com/plugins/spectro/

    Photosounder is the closest I can think of, from reading your original post.
    It is not free, and I do not seem to remember it having a free demo that you could try either.
    I have used it once or twice to cleanup sounds. The editing is basic and it is quite slow (has to re-render the sound after changes)
    Transients usually suffer baddly, although there are ways to fix that.

    Have you tried SPEAR?
    http://www.klingbeil.com/spear/
    I have not tried it myself, so cannot comment on usability or quality.

    I want to believe.

    Thanks for that link. The results with SPEAR are more like the original than "Virtual ANS",

    I think we have a winner.
    ["laoe" requires Java to be installed beforehand.
    To run "laoe" on windows right-click on "laoe.bat" (a windows batch file) then select "run as administrator" ].

    Not sure if you are still looking.
    I found a reference on my notes to this plugin, which has been on my "to try" list. - If only I had the time...

    ocenaudio is a lovely-looking audio-editor ...

    ( a lot better than similar freebies like Audacity ),
    but it doesn't offer editing via spectrogram, (like "laoe").
