Detailed Description

Session latency monitor.

• calculates session latency
• calculates session scaling factor
• trims scaling factor to the allowed range
• updates resampler scaling
• shutdowns session if the latency goes out of bounds

Constructor & Destructor Documentation

LatencyMonitor()

roc::audio::LatencyMonitor::LatencyMonitor	(	const packet::SortedQueue &	queue,
		const Depacketizer &	depacketizer,
		ResamplerReader *	resampler,
		const LatencyMonitorConfig &	config,
		core::nanoseconds_t	target_latency,
		size_t	input_sample_rate,
		size_t	output_sample_rate
	)

Constructor.

Parameters

• queue and depacketizer are used to calculate the latency
• resampler is used to set the scaling factor, may be null
• config defines various miscellaneous parameters
• target_latency defines FreqEstimator target latency, in samples
• input_sample_rate is the sample rate of the input packets
• output_sample_rate is the sample rate of the output frames
