from the .au format specification:
http://www.opengroup.org/public/pubs/external/auformat.html

* When audio files are passed through pipes, the 'data_size' field may
not be known in advance.  In such cases, the 'data_size' should be set
to AUDIO_UNKNOWN_SIZE.

typedef struct {        
u_32  magic;  /* magic number */  
u_32  hdr_size;  /* size of this header */   
u_32   data_size;  /* length of data (optional) */   
u_32   encoding;  /* data encoding format */  
u_32   sample_rate;  /* samples per second */  
u_32   channels;  /* number of interleaved channels */  
} Audio_filehdr;       

It would be nice, if ogg123 and eggenc would support the au format.
