Introducing Song Form Intelligence into Streaming Audio

Kevin Curran


When receiving streaming media over a low bandwidth wireless connection, users can experience not only packet losses but also extended service interruptions. These dropouts can last for as long as 15 sec. During this time no packets are received and if not addressed, these dropped packets cause unacceptable interruptions in the audio stream. A long dropout of this kind may be overcome by ensuring that the buffer at the client is large enough. However, when using fixed bit rate technologies such as Windows Media or Real Audio, this may only be done by buffering packets for an extended period (10 sec or more) before starting to play the track. During this period, many users are likely to lose interest or become frustrated. This research presents a novel semantic audio error concealment buffering technology, made possible by the song form structure. It enables the audio to start playing within two or three sec, while at the same time using a small proportion of the available bandwidth to fill the client device buffer with received packets but categorised into structures of the song. A pattern matching run-time algorithm works to identify portions of the audio stream and when a dropout does occur relevant section of the buffered audio are inserted so as to create a perfect match for the lost audio. Our algorithm can be shown to increase reliability on bursty wireless networks.
