I don't see any particular reason why we should be concerned whether audio is speech or something else. After all, the user that doesn't want to modify the time-scale simply won't bother--so no harm. Of course a musician who wants to work with moded audio is likely to get the highest quality tool available, which may well not be the browser. Janina
