PercivalEnhanceHarmonics¶

Inputs¶

• array (vector_real) - the input signal

Outputs¶

• array (vector_real) - the input signal with enhanced harmonics

Description¶

This algorithm implements the ‘Enhance Harmonics’ step as described in [1].Given an input autocorrelation signal, two time-stretched versions of it scaled by factors of 2 and 4 are added to the original.For more details check the referenced paper.
