Statistics about the processor state.

Fields

has_voice: Option<bool>

True if voice is detected in the current frame.

has_echo: Option<bool>

False if the current frame almost certainly contains no echo and true if it might contain echo.

rms_dbfs: Option<i32>

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: Option<f64>

Prior speech probability of the current frame averaged over output channels, internally computed by noise suppressor.

residual_echo_return_loss: Option<f64>

RERL = ERL + ERLE

echo_return_loss: Option<f64>

ERL = 10log_10(P_far / P_echo)

echo_return_loss_enhancement: Option<f64>

ERLE = 10log_10(P_echo / P_out)

a_nlp: Option<f64>

(Pre non-linear processing suppression) A_NLP = 10log_10(P_echo / P_a)

delay_median_ms: Option<i32>

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: Option<i32>

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: Option<f64>

The fraction of delay estimates that can make the echo cancellation perform poorly.
