SoundWIRE, which stands for Sound Waves on the Internet from Real-time Echoes, is a research group investigating streaming audio and underlying network performance characteristics. A novel utility developed by the group measures network delay by recirculating a basic signal between two hosts. "The internet connection itself is thereby converted into a vibrating acoustic medium, producing a resonating tone" that has a frequency (i.e., pitch) proportional to the roundtrip time. This ingenious method is described in detail on the group's homepage. Several research and conference papers can also be downloaded. A number of SoundWIRE experiments are also highlighted, including one that demonstrated Audio Teleportation. This accomplishment was performed with an electronic cello accompanied by its own echo, which was produced by recirculating the cello's signal across several hundred miles via the Internet.
