fileName

Name of the audio file to be created.

• This method is very useful for extracting audio (wave) data from a DICOM object of type "Basic Voice Audio" (1.2.840.10008.5.1.4.1.1.9.4.1), which is typically used for report dictation.
• The resulting wave file has the following characteristics:
  1. Number of channels: will either be 1 or 2, based on the value of the number of channels for this multiplex group. You can call ChannelCount to get the number of channels in a multiplex group.
  2. Bits per sample (sample size) will always be 8.
  3. Samples per second (sampling rate): This will be the same as the sampling frequency for the waveform group, call GetSamplingFrequency to get this value.
  4. Format category: PCM, mu-Law or a-Law, based on the value of the waveform sample interpretation which can be retrieved by calling GetSampleInterpretation.

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
