Another way of saying this is that the generated waveform of an Oscillator will have maximum peak value at 0dBFS. Conveniently, this corresponds to the full-range of the signal values used by the Web Audio API. Because the WaveTable will be normalized on creation, the real and imag parameters represent relative values." This does not clearly define what normalization must be performed. Should/can the normalization be performed analytically, or should one period be generated and the maximum (absolute) value in that period be found? These approaches may not arrive at the exact same normalization level, so a sample-exact test suite would not be possible. 113908 1 olivier.thereaux 2014-10-28 17:14:20 +0000 Web Audio API issues have been migrated to Github.
