Aliasing cancellation in audio effects algorithms |
摘要 |
A method for effecting aliasing cancellation in an audio effects algorithm using a delay modulated signal, derived from interpolation of a delay modulator at an instantaneous sampling frequency, including: determining the instantaneous sampling frequency 1/T<SUB>isf </SUB>and band limiting an input signal, to which the audio effects algorithm is to be applied to ½ T<SUB>isf </SUB>prior to interpolation. |
