Abstract
Congestion control for compressed audio is a nontrivial pursuit. Audio perception is highly susceptible to disturbance in temporal quality. We recently proposed and implemented a novel symbiotic perceptual audio streaming mechanism, which receives fast feedback from network and responds to impending congestion with advanced auditory perception based adaptation techniques and supports near flawless sound. The design is based on recently proposed iTCP. It enables a new principle where encoder trade-off fidelity for accurate audio temporal quality using fast network event feedback. We have tested it live over the Internet. In this paper, we share the performance of this system and report observed improvements in time-bounded streaming audio.
