Subjective Audio Quality Test — MPEG Surround

Late in 2006 I designed and supervised a subjective audio quality test of the MPEG-D MPEG Surround technology. The technology is able to represent a 5.1 channel audio signal as a stereo signal with a bitrate of 128 kb/s to as slow as 64 kb/s, such that it can be a “drop-in” replacement to give current stereo services a 5.1 channel capability. The report, N8851 Report on MPEG Surround Verification Tests, is available at
