What is the EBU SQAM test material, what does it contain, and what use does the EBU allow?

The EBU SQAM CD (handbook Tech 3253, September 2008) is a set of recordings for subjective sound-quality tests, grouped from alignment and artificial signals through single instruments, voice, speech, orchestra and pop (70 tracks). The handbook states no licence. The EBU's generic test-sequence terms forbid commercial use and redistribution, and the producer's reading of the SQAM download page says downloading means agreeing to R&D-only use. Curator qualifications: Documents read 2026-10-22; no test sequence downloaded or used. EBU test sequences: internal R&D equipment assessment only; no commercial use; no copying, publishing or redistribution (hold). SQAM-specific linkage to the July 2019 terms is from the producer's condensed landing-page read. Limitations: Documents read 2026-10-22; no test sequence downloaded or used. SQAM landing page (403 to producer) not read by curator. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
