Since its finalization in 2001 Recommendation ITU-R BS.1534, nicknamed MUSHRA (multi stimulus with hidden reference and anchors), for testing audio quality has become very popular. It is widely used and to some extent misused. Many recent studies have also identified limitations of the current Recommendation. These limitations can have a direct impact on the interpretation of data collected using ITU-R BS.1534. ITU-R WP 6C is currently working on a revision of MUSHRA. The modification should preserve the general multiple-stimulus-hidden-reference (MUSHRA) design characteristic of ITU-R BS.1534 while improving the robustness and testing reliability. This workshop will present current discussions and results from the autumn 2012 meeting of ITU-R.
