pulp::view::MeterFrame Struct Reference

A single multi-channel meter reading. More...

#include <value_source.hpp>

Public Attributes
std::array< float, kMaxChannels >	rms {}
std::array< float, kMaxChannels >	peak {}
int	channels = 0
	Number of valid channels in rms/peak.

Static Public Attributes
static constexpr int	kMaxChannels = 8

Detailed Description

A single multi-channel meter reading.

Fixed-capacity and trivially copyable so it can ride a TripleBuffer with no allocation on the publish path. Stereo is the common case; kMaxChannels is the surround ceiling.

Member Data Documentation

channels

int pulp::dataplane::MeterFrame::channels = 0

Number of valid channels in rms/peak.

Publishers should keep this in [0, kMaxChannels]; consumers must still bound their index by min(channels, kMaxChannels) since publish() stores the frame verbatim and never trusts the count to gate an array access.

kMaxChannels

int pulp::dataplane::MeterFrame::kMaxChannels = 8

staticconstexpr

peak

std::array<float, kMaxChannels> pulp::dataplane::MeterFrame::peak {}

rms

std::array<float, kMaxChannels> pulp::dataplane::MeterFrame::rms {}
