      audioConfigurations.sampleRate = WSSAudioSampleRate44KHz;
      audioConfigurations.bitRate = WSSAudioBitRate96Kbps;
      audioConfigurations.numOfChannels = 2;
      audioConfigurations.frameSize = 16;
      _videoCompression = [[WSSVideoCompression alloc] initWithVideoConfigurations:videoConfigurations audioConfigurations:audioConfigurations];
