Spectrogram blurred at low zoom

Spectrogram blurred at low zoom.

For comparison, the same file in SpectraLayers.

Please fix this.

Thank you.


You can tweak the visual aspect in many ways in the preferences:

image

I know these functions.

The spectrogram shows well in larger frequency range zoom.

When I reduce the frequency range zoom it creates a blur.
Blur appears when the right knob is at 0.

SpectraLayers does not have this problem.

These are my settings.
Set

Blur appears when the right knob is at 0.





When I set the right knob to more than 0.
There is no blur like before.

Forgive me - could you explain what you mean by ‘…the right knob is at 0’. There are no ‘knobs’ in that dialog box…

zoom knob

I mean the zoom wheel.

Sorry for the bad translation.

Do you mean with the “right knob” the Vertical Zoom scroll wheel? → Yes

I do get what you mean, understanding that you “squish” the lower Main View area. Seems like some kind of interpolation effect to me. After all, when you want to display like 2048 bands at once and allow less and less space for these bands, there muss be some kind of reduction/combination in what to show and what not. When you zoom in, of course there is space for less bands to be displayed.

Not sure if I would consider this an issue.
I do agree though that SpectraLayers handles the display better (with the same settings and roughly the same “squish”). But SpectraLayers is built as an spectral centered editor to begin with. Maybe PG can do some tweaks to this.

I don’t know much about graphics.
Maybe it’s not a big problem for programmers
to fix it.

I work a lot on spectrogram.
I’d like to see better details in small zoom.
I have a small monitor on my laptop.

Here is a spectrum of a stereo file in WL6


Here is the same stereo file in WL12

Wavelab 12 shows well with a larger zoom.
However, when you squeeze more, there is blur.
You can see it in the video at low frequencies.
Maybe it’s some kind of averaging.
I would like it to look better, without blur.

What is the peak of your audio file? Can you try to make it -1dB temporarily and see the spectrum again?

Peak -2.3 dB
After turning it down a few dB it remains as blurry as before.

I hope this is discussed with Spectralayers and fixed soon.
