Member Function Documentation

void ADR_CALL audiere::SineWave::getFormat (  int &    channel_count, int &    sample_rate, SampleFormat &    sample_format )  [inline, virtual]

Retrieve the number of channels, sample rate, and sample format of the sample source. Implements audiere::SampleSource. Definition at line 17 of file tone.cpp. References ADR_CALL, audiere::hidden::sample_format, audiere::SampleFormat, and audiere::SF_S16.

int ADR_CALL audiere::SineWave::read (  int    frame_count, void *    buffer )  [inline, 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 27 of file tone.cpp. References ADR_CALL, and audiere::s16.

void ADR_CALL audiere::SineWave::reset (    )  [inline, 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 42 of file tone.cpp. References ADR_CALL.
