bool AUFile::cutSampleRange (  unsigned int    length )

Shrink an AU file to the usable samplerange. Parameters: length  Length of the samplerange Returns: true if successful, false if failed

vector< double > & AUFile::getData (  void    )

Getter for the audio data stream

const char * AUFile::getFilename (  void    )

Getter for the filename. Returns: filename of the au-file this object contains.

AU_info_data * AUFile::getInformation (  void    )

Getter for the additional header information

unsigned int AUFile::getSize (  void    )

Getter for the audio stream size

void AUFile::normalize (  void    )

The header of the au-file.

char* AUFile::filename [private]

Filename when loaded from file or NULL when new object.

AU_info_data AUFile::i_data [private]
