Audio latency target to maintain. These settings are used to adjust the clock speed in order to match the measured audio latency to a specified value.

Fields

hdr: MMAL_PARAMETER_HEADER_T

enable: MMAL_BOOL_T

< whether this mode is enabled

filter: u32

< number of latency samples to filter on, good value: 1

target: u32

< target latency (microseconds)

shift: u32

< shift for storing latency values, good value: 7

speed_factor: i32

< multiplier for speed changes, in 24.8 format, good value: 256-512

inter_factor: i32

< divider for comparing latency versus gradiant, good value: 300

adj_cap: i32

< limit for speed change before nSpeedFactor is applied, good value: 100
