Padding broken in fluid.bufloudness?

Bug Reports and Issues
1

Before filing a proper bug report on git, I want to check here in case I’m overlooking something.

But it seems like @padding 0 in fluid.bufloudness~ isn’t working properly?

According to the reference:

No padding - The first analysis window starts at time 0, and the samples at either end will be tapered by the STFT windowing function.

This leads me to believe that it would still be more than one frame of analysis (for most settings).

In this example with @hopsize 64 and @numframes 1024 @windowsize 1024, having @padding 0 returns a single frame/channel of analysis.

if there is no padding, how do you expect it, with 1024 frames to analyse with a 1024 window, to hop anywhere?

frame 0= 0-1024
done :slight_smile:

There is this thread where we explain all of this with a patch. let me find it for you

ok here we go

I never pushed because I need help to review. Fancy helping? There are a few of these that need English language and general readability check (and SC coding but hey if it is live I can push the sc code soon after)

in this specific case, we need someone to do a lean learn page to host this patch and explain what it is for. taking examples from other lean learn pages.

Gotcha. I just use @padding 2 everywhere else (except for with sine-based things), so was confusing to see that.

Yeah this patch is super super useful. I guess the time for that kind of development has passed, but this would be really nice as an interactive thing on the learn page (ala the other interactive examples).

indeed it would. feel free to post a PR :wink:
