A method of determining if an echo canceller comprised in a communication channel that is used to transmit at least one tonal signal and characterized by a model echo path of the channel, is acceptably adapted to cancel echoes in the channel, the method comprising: determining a performance measure how well the canceller cancels echoes of at least one test signal characterized by at least one frequency different from a frequency of the at least one tonal signal; and determining if the canceller is acceptably adapted responsive to the measure.

Method and apparatus for retraining of echo cancellation

Disclosed is a method and circuit for echo suppression or cancellation. According to some embodiments of the present invention, there is provided a circuit including a Noise-Enhanced-Receiving-Direction unit and Narrow-Band Remover unit or units.

Circuit method and system for transmitting information

A method for using a waveform segment in place of a missing portion of an audio waveform generated in response to a packet stream encoding portions of the audio waveform, the method comprising: phase matching a trailing portion of the waveform segment with a trailing portion of the audio waveform that follows the missing portion; and adding the phase matched waveform segment to the audio waveform.
