Hello,

 

Anyone know how those tangent values in .fraw/.fraw2 files are computed ?

We're doing a little application to get fcurves from sound ..by using a selected frequency (not global amplitude) ...but i can't understand what those tangent numbers derive from ... Any ideas?

 

There's always the option of exporting linear keys ...but what would be nice is to get a nice bezier with as few keys as possible....

 

Cheers
