    This is the class that serves as an interface between the library's audio
    output and the audio playback library of your choice.
    The class gets mono or stereo PCM data in in floating point data

        int mFreq;
        //! Mono or stereo
        int mNumChannels;

        TheoraVideoClip* mClip;

        virtual ~TheoraAudioInterface();

    //! A function that the TheoraVideoClip object calls once more audio packets are decoded
      \param data contains one or two channels of float PCM data in the range [-1,1]
      \param nSamples contains the number of samples that the data parameter contains in each channel

        virtual void insertData(float** data,int nSamples)=0;

        virtual void destroy() = 0;
