[speex-dev] framesize v/s audio buffer size

Im new to speex, and im trying to use it in my application to transmit
speech over multicast.
I've done some test, but i have some questions. First, I'm reading audio
with a buffer of 512 bytes, but the speex frames are 160 (using
SPEEX_GET_FRAME_SIZE), so i have to manually divide the 512 bytes (256
16bit samples) in blocks of 160 float samples. Using 1 frame, i dispatch
the first 160 samples, but there are 96 (256-160) samples remaining. What
can i do with them ? I need to send them as soon as posible, so i guess i
cant just wait until the next audio buffer comes to push the data inside
the codec. I dont even know if the sound card will produce more audio
because before getting here, the audio have to pass some noise level. If
the audio is not louder enought i will not get any data.
Any ideas ?
Thanks in advance.
