Overview

This interface describes the parameters for acoustic echo cancelation.

A BZAECParams object can be created as follows:

BZAECParams* bzAECParams = [[BZAECParams alloc] init];

Swift
let bzAECParams = BZAECParams()

Tasks

  •   m_bAECMobile

    This parameter specifies whether acoustic echo cancelation is running on a mobile device or not. Default: FALSE.

           property
  •   m_eAECMobileMode

    This parameter the acoustic echo cancelation mobile mode as defined in BZAecmModes. Default: BZAecmModes:BZAECMM_Speakerphone.

           property
  •   m_bEnableAECMobileComfortNoise

    This parameter specifies whether to enable acoustic echo cancelation mobile comfort noise. Comfort noise replaces suppressed background noise to maintain a consistent signal level. Default: FALSE.

           property
  •   m_bEnableDriftCompensation

    This parameter specifies whether or not to enable drift compensation. Default: FALSE.

           property
  •   m_nDelayOffsetMs

    This parameter specifies delay offset in milliseconds. This is an important parameter to tune and is dependent on the device hardware/software. Default: BZAECDefaultParams:AEC_DEFAULT_DelaytOffsetMs.

           property
  •   m_bEnableLevelEstimatorAEC

    This parameter specifies whether or not to enable level estimator. Default: FALSE.

           property
  •   m_bEnableEcDataDump

    This parameter specifies whether or not to enable echo canceler data dump. Warning: This results in large amount of data to be dumped/logged. Default: FALSE.

           property
  •   m_bEnableAecCoreDataDump

    This parameter specifies whether or not to enable acoustic echo cancelation core data dump. Warning: This results in large amount of data to be dumped/logged. Default: FALSE.

           property
