I'm using Speex on a VoIP development platform almost successfully. I
have troubles only on some Duron and Pentium processors (~800Mhz): on
Windows NT (4.0, 2000 or XP), there isn't enough time to process the
encoding thread, still using THREAD_PRIORITY_TIME_CRITICAL (it takes
about 10-20% of overall processor time using the 5900kbps bitrate). A
symptom (on these platforms) is to get some processing jitter when you
exchange the foreground application.
