SaveAudio Method
Summary
Creates an audio (wave) file from the channels in the waveform group.
Syntax
public void SaveAudio(string fileName)
Public Sub SaveAudio( _ByVal fileName As String _)
public void SaveAudio(string fileName)
function Leadtools.Dicom.DicomWaveformGroup.SaveAudio(fileName)
public:void SaveAudio(String^ fileName)
Parameters
fileName
Name of the audio file to be created.
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:
- 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.
- Bits per sample (sample size) will always be 8.
- Samples per second (sampling rate): This will be the same as the sampling frequency for the waveform group, call GetSamplingFrequency to get this value.
- Format category: PCM, mu-Law or a-Law, based on the value of the waveform sample interpretation which can be retrieved by calling GetSampleInterpretation.
Example
For an example, refer to WaveformGroupCount.
