Spectrogram is offset / ugly in v6.52 (FIXED)

TobyAM · 03-23-2022, 02:19 PM

I've noticed that the spectrogram looks quite delayed, offset in time, and interpolated in a really ugly way when zoomed out. Reverting to 6.51 fixes this, and looks "normal."

Take a screenshots.

Yeah screenshots would help. Are you rebuilding peaks with each or just viewing them?

Original spectrogram from 6.51 viewed in 6.52 are normal:

Spectrogram rebuilt in 6.52:

cache resolution is 600

I experienced the same thing today after updating and came here to see if it was mentioned anywhere. Same exact thing is happening for me depending on the zoom level.

Played around with the peaks cache size and there seems to be an inverse relationship between higher sizes and lower quality interpolation.

cache 2000 looks like legos
cache 100 looks beautiful

Edit: Either way there's a really bad timing offset when zoomed out, can't find an accurate setting, so I'm gonna have to revert. Such a shame, the parallel processing is so nice!

Thanks, ahh you said spectral peaks this is spectrogram!

Can you send (a link to) that file to support at cockos dot com?

Oops, my bad. I'll correct my vernacular. An example spectrogram comparison session has been emailed to you!

Thanks, it should be fixed in today's coming +dev build (and a 6.53 soonish). As a side note, the 6.51 and previous behavior wasn't ideal, so the new builds will be slightly different (better!).
