Public Member Functions inherited from NAudio.Wave.WaveStream
override void	Flush ()
	Flushes the buffer of the current stream and causes any buffered data to be written to the underlying device.

override long	Seek (long offset, SeekOrigin origin)
	Sets the position within the current stream.

override void	SetLength (long length)
	Throws a NotSupportedException with the message "Can't set length of a WaveFormatString".

override void	Write (byte[] buffer, int offset, int count)
	Throws a NotSupportedException with the message "Can't write to a WaveFormatString".

void	Skip (int seconds)
	Skips the playback to a new position in the audio file based on the specified number of seconds.

virtual bool	HasData (int count)
	Checks if there is data available at the current position.

Protected Member Functions
override void	Dispose (bool disposing)

Detailed Description

WaveStream that converts 32 bit audio back down to 16 bit, clipping if necessary.

Constructor & Destructor Documentation

◆ Wave32To16Stream()

NAudio.Wave.Wave32To16Stream.Wave32To16Stream ( WaveStream sourceStream )

inline

Creates a new Wave32To16Stream.

Parameters

sourceStream the source stream

Member Function Documentation

◆ Convert32To16()

unsafe void NAudio.Wave.Wave32To16Stream.Convert32To16	(	byte[]	destBuffer,
		int	offset,
		byte[]	source,
		int	bytesRead )

inlineprivate

Converts 32-bit audio samples to 16-bit audio samples and writes the result to the destination buffer.

Parameters

destBuffer	The destination buffer to write the 16-bit audio samples to.
offset	The offset in the destination buffer to start writing the samples.
source	The source buffer containing the 32-bit audio samples.
bytesRead	The number of bytes read from the source buffer.

This method converts the 32-bit audio samples in the source buffer to 16-bit audio samples and writes the result to the destination buffer. It also applies volume scaling and handles clipping if the sample value exceeds the range of a 16-bit integer. The method uses unsafe code to work with pointers for better performance.

Here is the caller graph for this function:

◆ Dispose()

override void NAudio.Wave.Wave32To16Stream.Dispose ( bool disposing )

inlineprotected

Releases the unmanaged resources used by the ClassName and optionally releases the managed resources.

Parameters

disposing true to release both managed and unmanaged resources; false to release only unmanaged resources.

This method releases the unmanaged resources used by the ClassName and optionally releases the managed resources. If disposing is true, this method releases all resources held by any managed objects that this ClassName references. This method is called by the public Dispose() method and the Finalize method.

◆ Read()

override int NAudio.Wave.Wave32To16Stream.Read	(	byte[]	destBuffer,
		int	offset,
		int	numBytes )

inline

Reads data from the source stream, converts it to 16-bit and writes it to the destination buffer.

Parameters

destBuffer	The destination buffer where the converted data will be written.
offset	The zero-based byte offset in destBuffer at which to begin storing the data.
numBytes	The maximum number of bytes to read from the source stream.

Returns: The actual number of 16-bit words read into destBuffer .

Exceptions

System.IO.IOException An I/O error occurs while reading from the source stream.

Implements NAudio.Wave.IWaveProvider.
