Member Function Documentation

OutputStream* ADR_CALL audiere::ThreadedDevice::openBuffer (  void *    samples, int    frame_count, int    channel_count, int    sample_rate, SampleFormat    sample_format )  [inline, virtual]

Open a single buffer with the specified PCM data. This is sometimes more efficient than streaming and works on a larger variety of audio devices. In some implementations, this may download the audio data to the sound card's memory itself. Parameters: samples  Buffer containing sample data. openBuffer() does not take ownership of the memory. The application is responsible for freeing it. There must be at least |frame_count * channel_count * GetSampleSize(sample_format)| bytes in the buffer. frame_count  Number of frames in the buffer. channel_count  Number of audio channels. 1 = mono, 2 = stereo. sample_rate  Number of samples per second. sample_format  Format of samples in buffer. Returns : new output stream if successful, 0 if failure Implements audiere::AudioDevice. Definition at line 168 of file device.cpp. References ADR_CALL, audiere::hidden::sample_format, and audiere::SampleFormat.

OutputStream* ADR_CALL audiere::ThreadedDevice::openStream (  SampleSource *    source )  [inline, virtual]

Open an output stream with a given sample source. If the sample source ever runs out of data, the output stream automatically stops itself. The output stream takes ownership of the sample source, even if opening the output stream fails (in which case the source is immediately deleted). Parameters: source  the source used to feed the output stream with samples Returns : new output stream if successful, 0 if failure Implements audiere::AudioDevice. Definition at line 164 of file device.cpp. References ADR_CALL.

void ADR_CALL audiere::ThreadedDevice::update (    )  [inline, virtual]

Tell the device to do any internal state updates. Some devices update on an internal thread. If that is the case, this method does nothing. Implements audiere::AudioDevice. Definition at line 161 of file device.cpp. References ADR_CALL.
