Hello Jean-Marc, > Got any luck with the Blackfin stuff? One thing I forgot mentioning that > would probably help a lot in narrowing down the bug is to simply disable > assembly functions one by one and see which one breaks Speex. sorry that I didn't reply for some days. Unfortunately I had some other serious problems with my software which are not related to Speex. I hope to solve

An update: I found that the "ADD32: output is not int:" messages are caused by the enhancer. When I turn the enhancer off, the messages vanish, but the "freak out" of the codec is still there - so the problem seems not to be related to the overflow messages. best regards, Frank ---------- Urspr?ngliche Nachricht --...

Hi all, This is Linfeng Zhang from Google. I'll work on ARM NEON optimization in the next few months. I'm submitting 2 patches in the following couple of emails, which have the new created celt_fir_neon(). I revised celt_fir_c() to not pass in argument "mem" in Patch 1. If there are concerns to this change, please let me know. Many thanks to your comments. Linfeng Zhang

Hi, In fixed point speex code there is no where satuartions checks are used. The basic arithmetic operations like ADD,ADD32,SUB,MUL etc. are just directly implemented without the saturation checks. Can u please comment on this. For the speex decoder testing, is there any standard streams? if yes from where can i get those?

Hi all, I am the developer of the llcon software (llcon.sf.net) which is a software making it possible for musicians to play in real-time over the internet. Up to now I have used ADPCM or no audio coding. Gregory Maxwell was pointing me to the great CELT project. Using CELT has the advantage to be able to use higher sample rates, getting lower code rate and better error concealment. I have
