Hi Jean-Marc,
yes, problem exists in narrowband-mode, too.
I already twiddled with max_gain, but did not have real success. I changed line 337 of ltp.c (function pitch_gain_search_3tap_vq)
if (sum>best_sum && gain_sum<=max_gain) {
to
if (sum>best_sum && gain_sum<max_gain) {
-- that stabilizes speex for 2000 Hz and 2200 Hz input on quality setting 7 (23800 bits/s) complexity 2, while it does not help much for quality setting 9 ((34400 bits/s) (just slightly reduces the d...
