       SDL_AudioCVT - Audio Conversion Structure


       typedef struct{
         int needed;
         Uint16 src_format;
         Uint16 dest_format;
         double rate_incr;
         Uint8 *buf;
         int len;
         int len_cvt;
         int len_mult;
         double len_ratio;
         void (*filters[10])(struct SDL_AudioCVT *cvt, Uint16 format);
         int filter_index;
       } SDL_AudioCVT;


       needed              Set to one if the conversion is possible

       src_format          Audio format of the source

       dest_format         Audio format of the destination

       rate_incr           Rate conversion increment

       buf                 Audio buffer

       len                 Length of the original audio buffer in bytes

       len_cvt             Length of converted audio buffer in bytes (calculated)

       len_mult            buf must be len*len_mult bytes in size(calculated)

       len_ratio           Final audio size is len*len_ratio

       filters[10](..)     Pointers to functions needed for this conversion

       filter_index        Current conversion function


       The  SDL_AudioCVT  is used to convert audio data between different formats. A SDL_AudioCVT
       structure is created with the SDL_BuildAudioCVT function, while the actual  conversion  is
       done by the SDL_ConvertAudio function.

       Many  of  the  fields in the SDL_AudioCVT structure should be considered private and their
       function will not be discussed here.

       Uint8 *buf

       int len

       int len_mult

       double len_ratio
