Center offset and weird behavior of lower part of the waveform (OutlineBuffer)

[TheOnlyJoey]

After doing my first implementation with the OutlineBuffer (based on the documentation in the Readme), I am running into the issue where there is a center deviation between the 2 halfs of the waveform, and the bottom half seems to behave weirdly.

Is this expected behavior and if so, how could this be solved?

Thanks

Apologies, I missed the comments to that repository for a while.
This looks indeed odd. I haven't seen that in the project where I use the OutlineBuffer.
Just to rule out some possibilities:
What is the buffer? Is that directly from the microphone?
Is there any chance that there are invalid numbers in it?

I don't know how to reproduce it at the moment, maybe you can post some information, like what OS, and if applicable share some code.

Thanks for the feedback
