#ACOUSTIC ECHO CANCELLATION FOR MUSIC FREE#

The output of the AEC block is fed to an acoustic noise cancellation (ANC) block where a spectral subtraction-based algorithm with an adaptive spectral floor estimation is employed.

A modified objective function is thereby derived for a gradient-based adaptive filter algorithm, and proof of its convergence to the optimum Wiener-Hopf solution is established. In order to overcome the major challenge of getting a separate reference signal in adaptive filter-based AEC problem, the delayed version of the echo and noise suppressed signal is proposed to use as reference.

Some high-end Telepresence systems already achieve life-like communication but are computationally demanding and prohibitively expensive.

High quality full-duplex Acoustic Echo Cancellation (AEC) is an integral component of a hands-free speakerphone communication system because it allows participants to converse in a natural manner (and without a headset!) as they would in person. The benefits include increased intelligibility and comprehension and a more pleasing communication experience. Speech processing is finally starting the transition to wider bandwidths.
