MO> To Jens Winkler and Farabi ibn Kora: I really would like to know what you are doing I have a test programm, that puts some hazard into speekers, and I am working on BSound. there are some things I not understand. what BSound::ReleaseRef BSound::AcquireRef should do? what Ref? its possible to load data from a file. shold reading run in own thread? the header has some "area" variables. which area? and, there is a constructor with load_into_memory = false. I think ther must be some prebuffer member. but its not so. what can it mean? -- Best regards, Farabi
