Frequency Shifter For Acoustic Feedback Reduction
https://www.sound-au.com/project204.htm
The fundamental process of the phase shifter is a 'Hilbert Transform'. The Hilbert transform of a signal x(t) is defined as the transform in which phase angle of all components of the signal is shifted by +/-90°. ... Unlike RF circuits where the frequency range is only a tiny fraction of the frequency in use, audio is assumed to cover the ...
Audio encoding using Huang and Hilbert transforms

the Hilbert transform of each IMF is called the Hilbert-Huang Transform (HHT). 4. PROPOSED APPROACH Compared to our recently published works [6],[7], where es-sentially extrema are encoded, in the present work IA and IP which are valuable pieces of information are exploited for coding. 4.1. Segmentation In the proposed method, the audio signal ...
