I'm trying out speex on the iPhone, and it seems to work great! But I'm trying to do speex encoding at the same time as a bunch of animation, and I'm just barely keeping it realtime. To give myself some head room, I'd like to try to get the arm optimizations compiled in. But I haven't had success. Before I list off all the things I've tried, has anyone gotten this to work? Or do we need a separate set of assembly optimized for a newer arm chip than 5e? I haven't learned much about arm asm yet.. (And if in my search, I missed a previous post explaining this, I apologize.) Thanks very much! Ben
