i am trying to add to my application the speex,i get stream of audio of wideband(16khz) and each smaple have 16 bit, as i understood from the manual is that speex get one frame at the time to encode , (one frame for wide band is 320 sample, mean 640 bit), after encode i send it on tcp\ip to the other size and then take the stream i got from the encoder and do decode.
i see that the buf i got after decoder has many zero , and not like the stream before.
i use quality=10 and stiil it sound bad!!!
what do i do wrong?

is it rigth that the encoder of wideband get frame at size 640 bit , and put them in float array of 320, and in decoder i get array of float of 320 and put them into 640 bit, each 4 bit insert to 2 bit of short?

i would be greatfull if someone who understand the code behind the speex could help me with this.


Thanks,
Ayelet
