A METHOD FOR REMOVING ALIASING IN WAVE TABLE BASED SYNTHESISERS
摘要
A method and apparatus are provided for changing the pitch of a tabulated waveform (x`n!) in wavetable based synthesizers. Harmonics that normally would be aliased before a transposition process are removed by a discrete time low pass filter at the same time that the tabulated waveform is reconstructed and resampled (120).
