Default What are spectral edits for?

It's easy to do in Reaper: Choose an item, draw a time
selection and tip on "spectral edit". The audio item becomes
very colourful, the y-axis is the frequency, the x-axis is
time and the colour represents the intensity (amplitude).
In a selected area in the x-y-field we can change the
gain, apply fades or compression.

But - and that is my question - what can we do with these
spectral edits? What is the practical use - for musicians or
producer?

--> How do you use spectral edits?

Predominantly as a fixer.

E.g allows you to better isolate and then treat a bad noise in a take by it's 'signature' e.g can see when it begins/ends, exactly what frequencies it occurs at and how loud it is compared to rest of sound at that time - so you only makes changes to the noise of interest.

Creative uses too of course, isolate parts, as a weird filter etc etc.

It's perfect for removing short events that don't belong (like a passing truck with no muffler, or a cough from the audience, or string squeaks from a guitar, for example). As BenK mentioned, there are a number of creative ways to use it too.

It's a complex tool, but very powerful. I recommend checking out the Kenny Goia video tutorial on using it effectively.

Thank you BenK-msx and Philbo King!

I see that spectral edits might be good for
removing bad noises (explosives, sibilants
etc.) and for removing unwanted sounds from
the background (passing truck etc.)

I wonder if it would be possible to improve
the sound of vocals by reducing nasality in
some syllables? Maybe there's some training
needed to realize which colours are
"nasality-colours".

Also: Is it perhaps possibe to improve vocal-lines
which had been transposed deeper by one octave?
Sometimes these tranposed wavs sound rather
strange, as if they came out of a metal tin.

Has anybody experiences in this regard with
spectral edits?

As an example: I used it to remove resonant whistles and bad 'essing' from a vocal. The spectra allow to see and home in on the offending frequencies. An awesome tool to have as standard in a DAW.
