Member Function Documentation

int audiere::WAVInputStream::doRead int  frame_count,
void *  buffer
[virtual]
 

Implement this method in subclasses.

Implements audiere::BasicSource.

Definition at line 79 of file input_wav.cpp.

References audiere::GetSampleSize(), audiere::BasicSource::read(), and audiere::SF_S16.

void audiere::WAVInputStream::getFormat int &  channel_count,
int &  sample_rate,
SampleFormat sample_format
[virtual]
 

Retrieve the number of channels, sample rate, and sample format of the sample source.

Implements audiere::SampleSource.

Definition at line 67 of file input_wav.cpp.

int audiere::WAVInputStream::getLength  )  [virtual]
 

Returns:
number of frames in the stream, or 0 if the stream is not seekable

Reimplemented from audiere::BasicSource.

Definition at line 128 of file input_wav.cpp.

int audiere::WAVInputStream::getPosition  )  [virtual]
 

Returns the current position within the sample source.

Returns:
current position in frames

Reimplemented from audiere::BasicSource.

Definition at line 142 of file input_wav.cpp.

bool audiere::WAVInputStream::initialize FilePtr  file  ) 
 

Todo:
this really should be replaced with a factory function

Definition at line 30 of file input_wav.cpp.

References ADR_LOG, and audiere::read32_le().

bool audiere::WAVInputStream::isSeekable  )  [virtual]
 

Returns:
true if the stream is seekable, false otherwise

Reimplemented from audiere::BasicSource.

Definition at line 122 of file input_wav.cpp.

void audiere::WAVInputStream::reset  )  [virtual]
 

Reset the sample source. This has the same effect as setPosition(0) on a seekable source. On an unseekable source, it resets all internal state to the way it was when the source was first created.

Implements audiere::SampleSource.

Definition at line 114 of file input_wav.cpp.

References audiere::File::BEGIN.

void audiere::WAVInputStream::setPosition int  position  )  [virtual]
 

Sets the current position within the sample source. If the stream is not seekable, this method does nothing.

Parameters:
position current position in frames

Reimplemented from audiere::BasicSource.

Definition at line 134 of file input_wav.cpp.
