Se puo' esserti utile, dal man di wodim:

 -audio If this flag is present, all subsequent tracks are written in CD-DA (similar to Red Book) audio format.  The file with data for this  tracks
              should  contain  stereo,  16-bit digital audio with 44100 samples/s.  The byte order should be the following: MSB left, LSB left, MSB right,
              LSB right, MSB left and so on. The track should be a multiple of 2352 bytes. It is not possible to put the master image of an audio track on
              a raw disk because data will be read in multiple of 2352 bytes during the recording process.

              If  a filename ends in .au or .wav the file is considered to be a structured audio data file.  wodim assumes that the file in this case is a
              Sun audio file or a Microsoft .WAV file and extracts the audio data from the files by skipping over the non-audio  header  information.   In
              all  other  cases, wodim will only work correctly if the audio data stream does not have any header.  Because many structured audio files do
              not have an integral number of blocks (1/75th second) in length, it is often necessary to specify the -pad option as well.  wodim recognizes
              that  audio  data in a .WAV file is stored in Intel (little-endian) byte order, and will automatically byte-swap the data if the CD recorder
              requires big-endian data.  wodim will reject any audio file that does not match the Red Book requirements of 16-bit stereo  samples  in  PCM
              coding at 44100 samples/second.

              Using  other structured audio data formats as input to wodim will usually work if the structure of the data is the structure described above
              (raw pcm data in big-endian byte order).  However, if the data format includes a header, you will hear a click at the start of a track.

              If neither -data nor -audio have been specified, wodim defaults to -audio for all filenames that end in .au or .wav and  to  -data  for  all
              other files.
