The higher the encoding bitrate is, the higher the encoding delay will  
be. Delay means the difference in time between starting the encoding and  
obtaining the output bitstream which can be several hundred  
milliseconds. To minimize this delay is important for all real-time  
applications like bi-directional communication in video conferencing  
systems, so you need specialized codecs for this purpose, e.g. the Low  
Delay object type for AAC general audio or others for speech content.

Maybe the Wiki of Audiocoding.com can give some help:
