I’m Writing an external based on the simple play~ object.
Thus I need to recreate my own play~ object source code.
I decided to modify the index~ code (in the SDK) to simply add an interpolation function.
I’ve tried with a simple linear interpolation and a cosinus one, but the results aren’t the same than in the original play~ object with a slower reading speed !
Maybe i forgot something in my own code :
– some errors or I missed something.
– or the original code implements an other interpolation algo (quad or cubic..) ?
– or there is a secret recipe ?
My object sounds better than the index~ one (thanks to the interpolation) but not like the original :
some artificial high frequencies appear, they didn’t with play~.
I wonder if play~ implements a high-cut filter to disable this or if it’s just due to his own interpolation algo ?
I’ve attached an archive file which contains my code with the builds external and its help pat which will show you better what i mean.
Thanks for read and reply.
Hi Vanille, please accept my apologies for this late response,
I think it was just due to a bad interpolation.
I’ve implemented a "4-point interpolation" like you suggest me, and it seems to work better.
see you, maybe in Montpellier (?).
