Member Data Documentation

PaTime PaStreamInfo::inputLatency

The input latency of the stream in seconds. This value provides the most accurate estimate of input latency available to the implementation. It may differ significantly from the suggestedLatency value passed to Pa_OpenStream(). The value of this field will be zero (0.) for output-only streams.

PaTime

PaTime PaStreamInfo::outputLatency

The output latency of the stream in seconds. This value provides the most accurate estimate of output latency available to the implementation. It may differ significantly from the suggestedLatency value passed to Pa_OpenStream(). The value of this field will be zero (0.) for input-only streams.

PaTime

double PaStreamInfo::sampleRate

The sample rate of the stream in Hertz (samples per second). In cases where the hardware sample rate is inaccurate and PortAudio is aware of it, the value of this field may be different from the sampleRate parameter passed to Pa_OpenStream(). If information about the actual hardware sample rate is not available, this field will have the same value as the sampleRate parameter passed to Pa_OpenStream().

int PaStreamInfo::structVersion

this is struct version 1
