Member Function Documentation

void audiere::Resampler::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 21 of file resampler.cpp. References audiere::hidden::sample_format, audiere::SampleFormat, and audiere::SF_S16.

int audiere::Resampler::getLength (    )  [virtual]

Returns : number of frames in the stream, or 0 if the stream is not seekable Implements audiere::SampleSource. Definition at line 154 of file resampler.cpp.

float audiere::Resampler::getPitchShift (    )

Definition at line 176 of file resampler.cpp.

int audiere::Resampler::getPosition (    )  [virtual]

Returns the current position within the sample source. Returns : current position in frames Implements audiere::SampleSource. Definition at line 166 of file resampler.cpp.

bool audiere::Resampler::isSeekable (    )  [virtual]

Returns : true if the stream is seekable, false otherwise Implements audiere::SampleSource. Definition at line 149 of file resampler.cpp.

int audiere::Resampler::read (  int    frame_count, void *    buffer )  [virtual]

Read frame_count samples into buffer. buffer must be at least |frame_count * GetSampleSize(format) * channel_count| bytes long. Parameters: frame_count  number of frames to read buffer  buffer to store samples in Returns : number of frames actually read Implements audiere::SampleSource. Definition at line 32 of file resampler.cpp. References audiere::u16.

void audiere::Resampler::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 74 of file resampler.cpp.

void audiere::Resampler::setPitchShift (  float    shift )

Definition at line 171 of file resampler.cpp.

void audiere::Resampler::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 Implements audiere::SampleSource. Definition at line 159 of file resampler.cpp.
