Changeset 628 for pjproject/trunk/pjmedia/src/pjmedia-codec/speex/gain_table.c

Timestamp:

Jul 26, 2006 5:04:54 PM (18 years ago)

Message:

• Bring speex codec up to date with their SVN trunk
• Speex codec should work in FIXED_POINT mode when PJ_HAS_FLOATING_POINT is set to zero.
• ulaw2linear will return zero if zero is given (this would make the VAD works better, and it also fixed click noise when call is established/hangup).
