Befaco Announcments Thread

Hi Dave, it’s certainly not intentional! There is oversampling in place but on reflection I think the default setting (x2) is not sufficient. I had experimented with ADAA for the implementation (effectively each square sums with a hard clipper between each sum), but didn’t get satisfactory results.

The hardware is analog (triangle core into comparator) so will not alias but it does sound incredible harsh (especially when base frequency is high). But there is (tonal) harsh and (atonal) aliasing and clearly the first is what is desired. I’ll certainly revisit the default settings, but also look at if the antialiasing can be improved otherwise. At x8 oversampling the CPU is 6% on my machine which feels high, so maybe x4 is a compromise.

Green naive, pink x4 oversampling. (currently default is x2 oversampling, not shown)

If you or others are interested, could we continue in the dev thread? Befaco modules development blog - #234 by hemmer
