Performance of Spatial Audio Using Dynamic Cross-Talk Cancellation
Creating a virtual sound scene with spatial distributed sources needs a technique to introduce spatial cues into audio signals and an appropriate reproduction system. In our case a complete binaural approach is used. It consists of binaural synthesis and head-tracked dynamic cross talk cancellation (CTC) for the reproduction of the binaural signal at the ears of the listener. In this paper performance and limitations of the complete system and also the various subsystems will be investigated and discussed. The channel separation of the dynamic CTC system is measured for various positions in the listening area as well as the subjective accomplishment of the localisation is examined in listening tests.
