\brief STK realtime audio (blocking) input class.
This class provides a simplified interface to RtAudio for realtime
audio input. It is a subclass of WvIn. Because this class makes
use of RtAudio's blocking output routines, its performance is less
robust on systems where the audio API is callback-based (Macintosh
CoreAudio and Windows ASIO).
audio input. It is a subclass of WvIn. This class makes use of
RtAudio's callback functionality by creating a large ring-buffer
from which data is read. This class should not be used when
low-latency is desired.
RtWvIn supports multi-channel data in interleaved format. It is
important to distinguish the tick() methods, which return samples
produced by averaging across sample frames, from the tickFrame()
methods, which return references or pointers to multi-channel
sample frames.
RtWvIn supports multi-channel data in both interleaved and
non-interleaved formats. It is important to distinguish the
tick() methods, which return samples produced by averaging across
sample frames, from the tickFrame() methods, which return
