Classes
struct	pulp::audio::AudioIoTiming
	Immutable control-thread snapshot of one audio route's I/O timing. More...
struct	pulp::audio::LatencySnapshot
	Control-thread composition of backend I/O timing with the graph's already computed total latency. More...

Enumerations
enum class	pulp::audio::AudioTimestampDomain : std::uint8_t { pulp::audio::unspecified , pulp::audio::device_sample_frames , pulp::audio::monotonic_host_time }
	Clock domain used by the backend's audio timestamps. More...
enum class	pulp::audio::AudioTimingSource : std::uint8_t { pulp::audio::unspecified , pulp::audio::device_clock , pulp::audio::os_estimate , pulp::audio::user_calibration }
	Authority behind the reported I/O timing. More...
enum class	pulp::audio::AudioTimingConfidence : std::uint8_t { pulp::audio::unavailable , pulp::audio::estimated , pulp::audio::reported , pulp::audio::calibrated }
