C# Class GSF.Media.WaveFormatChunk

Represents the format chunk in a WAVE media format file.

Inheritance: RiffChunk, ISupportBinaryImage

Public Methods

Method	Description
CastSample ( double sample ) : LittleBinaryValue	Casts sample value to its equivalent native type based on defined BitsPerSample and AudioFormat.
Clone ( ) : WaveFormatChunk	Creates a copy of the WaveFormatChunk.
GenerateBinaryImage ( byte buffer, int startIndex ) : int	Generates a binary representation of this WaveFormatChunk and copies it into the given buffer.
GetSampleTypeCode ( ) : TypeCode	Determines sample data type code based on defined BitsPerSample and AudioFormat.
ParseBinaryImage ( byte buffer, int startIndex, int length ) : int	Parses WaveFormatChunk object by parsing the specified buffer containing a binary image.
WaveFormatChunk ( int sampleRate, short bitsPerSample, short channels, ushort audioFormat ) : System	Constructs a new WaveFormatChunk using the specified audio parameters.
