In fact, I think this is a great opportunity to also fix this bug https://github.com/pure-data/pure-data/issues/371 which is totally related. I just reopened https://github.com/pure-data/pure-data/issues/105 as well as I'm still considering the table could/should be still "perfectly symmetric" considering 0 crossings and the start/end points. > > On Wed, Jun 5, 2024 at 12:52 PM Alexandre Torres Porres <[email protected]> > wrote: > >> For the record and sake of comparison, Cyclone uses a 16384 points table, >> and linear interpolation, calculated with double precision.
