i have live streaming audio which i am encoding using a low bit rate codec,actually this question is based on packetization of the encoded data which is a after math of processing and pre process while giving it to a wireless device

Going Deep in to the discussion:

>Essentially while using VBR silence is encoded at 2Kbps and voice is encoded at 4Kbps

> my frame size 20ms

> if encoded at 4Kbps i need 10bytes

>if encoded at 2Kbps i need 5bytes for encoded data

>My payload size is 80bytes fixed

so now in order to fill the 80bytes payload i have to wait for complete 320ms if it is the case of silence

if its voice i have to wait for 160ms of data from microphone to fill the payload

my big question is `"is this is how Variable bitrate implemented in real time"`

how a VBR packetization is actually done
