  • Method and apparatus for using a waveform segment in place of a missing portion of an audio waveform
    Patent number: 7869992
    Abstract: 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.
    Type: Grant
    Filed: May 24, 2007
    Date of Patent: January 11, 2011
    Assignee: AudioCodes Ltd.
    Inventors: Mark Raifel, Guy Shterlich, Yakov Chen
  • Circuit method and system for transmitting information
    Patent number: 7856087
    Abstract: Disclosed is an echo suppresser or cancellation circuit including a speech signal extrapolation unit. The speech extrapolation unit may provide extrapolated signal segment approximations to an echo segment replacement unit. The echo segment replacement unit may replace a segment of a first speech signal suspected of being corrupted with an echo component of a second signal using the extrapolated signal segment approximated to represent the corrupted signal segment.
