registerAudioProcessor method

Future<int?> registerAudioProcessor(IAudioFrameProcessor processor)

@detail api @author gongzhengduo @brief Register a custom audio preprocessor.
After that, you can call enableAudioProcessor{@link #RTCEngine#enableAudioProcessor} to process the audio streams that either captured locally or received from the remote side. RTC SDK then encodes or renders the processed data. @param processor Custom audio processor. See IAudioFrameProcessor{@link #IAudioFrameProcessor}。
SDK only holds weak references to the processor, you should guarantee its Life Time. To cancel registration, set the parameter to nullptr. @return - 0: Success. - < 0 : Fail. See ReturnStatus{@link #ReturnStatus} for more details. @note

• When this interface is repeatedly called, only the last call takes effect.
• Refer to Custom Audio Processing for more information.

Implementation

Future<int?> registerAudioProcessor(IAudioFrameProcessor processor) async {
  $a() => ($instance as $p_a.RTCEngine).registerAudioProcessor(
      packObject(processor, () => android_IAudioFrameProcessor()));
  $i() => ($instance as $p_i.ByteRTCEngine).registerAudioProcessor(
      packObject(processor, () => ios_IAudioFrameProcessor()));

  if (Platform.isAndroid) {
    return $a();
  } else if (Platform.isIOS) {
    return $i();
  } else {
    throw UnsupportedError(
        'Not Support Platform ${Platform.operatingSystem}');
  }
