#include <RtWvOut.h>
Inheritance diagram for RtWvOut:
This class provides a simplified interface to RtAudio for realtime audio output. It is a subclass of WvOut. This class makes use of RtAudio's callback functionality by creating a large ring-buffer into which data is written. This class should not be used when low-latency is desired.
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 take a pointer or reference 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. 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. |
