fileName
Name of the audio file to be created.
Creates an audio (wave) file from the channels in the waveform group.

fileName
Name of the audio file to be created.

Example

For an example, refer to DicomDataSet.WaveformGroupCount.

Remarks

  • 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 Leadtools.Dicom.DicomWaveformGroup.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 DicomWaveformGroup.GetSampleInterpretation.

Requirements

Target Platforms: Silverlight 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
