sinusoids~ Bandwidth Enhanced Mode Crackle

[wagne342]

From Alessandro Ratoci: "As long as there’s more than one partial in bandwidth enhanced mode, the object starts to crackle in an unwelcome way (with strong DC components usually). Here a small patch reproducing the bug:

Comment: It appears that this issue has cropped up in the past when the object was first compiled for Intel processors. Per notes:

VERSION 1.9: Changed click problem on Intel by removing small random numbers from table, tweaked compiler options for performance, removed NTABSZ.

It may be that something similar is going on with regard to the recent ARM64 update. Investigating.

Thanks for opening the case! This happens on both Intel and ARM64 Machines

Hello, any news? is there anybody still maintaining this project? I hope so as it still has a great potential...

[ratoci]

bumping and hoping for the best!

@ratoci Thanks for keeping this on our radar. Due to short staffing, CNMAT externals are currently only minimally maintained by one person (me) so addressing these types legacy issues proceeds in bursts of activity as time allows.

Thank you very much for keeping this alive! A.

I was about to report this exact same issue... too bad it's still broken in latest release, BWE mode used to sound great !
I really hope it will be fixed.. someday !
Happy new year :-)
