Hi People,
I have speex 1.2beta3 installed in my server and asterisk 1.4.2, now I want to transcode from speex to ulaw or alaw but I have problems with this…
What happens is that the end using ulaw/alaw hears very clearly, but the end using speex only gets some weird noise… so I’m guessing the re-encoding into speex not working well.
I’m not a sound processing expert so CBR,VBR and the other parameters don’t really mean much to me, maybe someone here can give a hand at WHAT CONFIG COULD [BASICALLY] BE A “STANDARD” CONFIG I CAN GET SOME USABILITY TO START WITH?
The following is my speex.conf:
[speex]
quality => 3
complexity => 0
enhancement => true
vad => true
vbr => false
abr => 0
vbr_quality => 0
dtx => true
preprocess => false
pp_vad => false
pp_agc => false
pp_agc_level => 8000
pp_denoise => false
pp_dereverb => false
pp_dereverb_decay => 0.4
pp_dereverb_level => 0.3
[plc]
genericplc => trueand this is show translation:
