Using object-based audio reproduction in live applications
* Presenting author
Object-based audio is an approach for spatial sound reproduction which overcomes fundamental problems of traditional channel based applications. A spatial audio production consists out of audio objects. The audio objects are defined by an input signal and its associated metadata. The input signal represents the sound which should be perceived e.g a violin or a female voice, while the metadata describes the unique characteristics of that input signal such as its spatial position, movement or gain. Based on the audio-object information the loudspeaker signals will be generated by means of real-time audio rendering. For this the audio renderer need to know the loudspeaker setup. Especially in live applications, this new approach has major advantages for creative professionals. This paper describes the application and experiences of object-based audio installations in famous venues throughout Europe.
