Hello, Hyee Wang. I'm currently working on project using AEC library. My colleague Paul Novodon already contacted you at http://lists.xiph.org/pipermail/speex-dev/2009-November/007550.html but you didn't answered. I'm starting to investigate this problem in a couple of days, and I really want to hear from you if you faced the described problem earlier and know the solution. Looking forward to hearing from you, Anton A. Shpakovsky Multimedia Software Developer TomskSoft LLC. -------------- next part -------------- An HTML attachment was scrubbed...
