Member Function Documentation

bool WaveNativeFileOut::Close

(

)

[virtual]

Close file.

This will update any internal chunk information and close file.

Implements AFileOut.

bool WaveNativeFileOut::Open	(	char *	fileName,
		long	sampleRate,
		int	numBitsPerSamp,
		int	numChannels
	)		[virtual]

Create output file.

Parameters:

[in]	fileName	path of file to create
[in]	sampleRate	sampling rate
[in]	numBitsPerSamp	number of bits per sample
[in]	numChannels	number of channels

Create audio file. Returns true if success, false if error.

Implements AFileOut.

long WaveNativeFileOut::Write	(	char *	buf,
		long	numBytes
	)		[virtual]

Write raw data.

Parameters:

[in]	buf	raw data to write
[in]	numBytes	number of bytes to write

Write raw sample data. This is called internally and the user will probably prefer one of the other writer functions.

Implements AFileOut.

long WaveNativeFileOut::WriteFloatFrames	(	float *	buf,
		long	numFrames
	)		[virtual]

Write 32-bit float samples.

Parameters:

[in]	buf	pointer to 32-bit float samples
[in]	numFrames	number of sample frames to write

Convert from 32-bit float samples to file format and write. Multi-channel data is specified in interleaved format. Return number of sample frames written.

Implements AFileOut.

long WaveNativeFileOut::WriteShortFrames	(	short *	buf,
		long	numFrames
	)		[virtual]

Write 16-bit integer samples.

Parameters:

[in]	buf	pointer to 16-bit integer samples
[in]	numFrames	number of sample frames to write

Convert from 16-bit integer samples to file format and write. Multi-channel data is specified in interleaved format. Return number of sample frames written.

Implements AFileOut.
