[−][src]Struct webrtc_audio_processing_sys::Stats
Statistics about the processor state.
Fields
has_voice: OptionalBool
True if voice is detected in the current frame.
has_echo: OptionalBool
False if the current frame almost certainly contains no echo and true if it
_might_ contain echo.
rms_dbfs: OptionalInt
Root mean square (RMS) level in dBFs (decibels from digital full-scale), or
alternately dBov. It is computed over all primary stream frames since the
last call to |get_stats()|. The returned value is constrained to [-127, 0],
where -127 indicates muted.
speech_probability: OptionalDouble
Prior speech probability of the current frame averaged over output
channels, internally computed by noise suppressor.
residual_echo_return_loss: OptionalDouble
RERL = ERL + ERLE
echo_return_loss: OptionalDouble
ERL = 10log_10(P_far / P_echo)
echo_return_loss_enhancement: OptionalDouble
ERLE = 10log_10(P_echo / P_out)
a_nlp: OptionalDouble
(Pre non-linear processing suppression) A_NLP = 10log_10(P_echo / P_a)
delay_median_ms: OptionalInt
Median of the measured delay in ms. The values are aggregated until the
first call to |get_stats()| and afterwards aggregated and updated every
second.
delay_standard_deviation_ms: OptionalInt
Standard deviation of the measured delay in ms. The values are aggregated
until the first call to |get_stats()| and afterwards aggregated and updated
every second.
delay_fraction_poor_delays: OptionalDouble
The fraction of delay estimates that can make the echo cancellation perform
poorly.
