This class provides a simplified interface to RtAudio for realtime audio output. It is a protected subclass of WvOut.
RtWvOut supports multi-channel data in interleaved format. It is important to distinguish the tick() methods, which output single samples to all channels in a sample frame, from the tickFrame() method, which takes a pointer to multi-channel sample frame data.

Default constructor. The device argument is passed to RtAudio during instantiation. The default value (zero) will select the default device on your system or the first device found meeting the specified parameters. On systems with multiple soundcards/devices, values greater than zero can be specified in accordance with the order that the devices are enumerated by the underlying audio API. The default buffer size of RT_BUFFER_SIZE is defined in Stk.h. An StkError will be thrown if an error occurs duing instantiation. |
|
Start the audio output stream. The stream is started automatically, if necessary, when a tick() or tickFrame method is called. |
|
Stop the audio output stream. It may be necessary to use this method to avoid undesireable audio buffer cycling if you wish to temporarily stop audio output. |
|
Output a single sample to all channels in a sample frame. An StkError will be thrown if an error occurs during output. Reimplemented from WvOut. |
|
Output each sample in vector to all channels in vectorSize sample frames. An StkError will be thrown if an error occurs during output. Reimplemented from WvOut. |
|
Output the frameVector of sample frames of the given length. An StkError will be thrown if an error occurs during output. Reimplemented from WvOut. |
