It seems superfluous, since the base frequency can simply be set to the desired (detuned) frequency instead of being calculated from frequency and detune. Suggestion: drop the detune attribute. 75757 1 crogers 2012-10-10 00:22:36 +0000 Fixed: https://dvcs.w3.org/hg/audio/rev/cb14c7445a27 The .detune attribute is important because common synthesis algorithms require controlling both the base frequency and a pitch offset. 76097 2 philipj 2012-10-12 12:42:59 +0000 Question answered by computedFrequency(t) = frequency(t) * pow(2, detune(t) / 1200) 114083 3 olivier.thereaux 2014-10-28 17:17:29 +0000 Closing.
