virtual AkReal32 AK::IAkMetering::GetKWeightedPower (  )  [pure virtual]

Get the mean k-weighted power value in this frame, used to compute loudness (as defined by ITU-R BS.1770). Depending on when this function is called, you may get metering data computed in the previous frame only.

Returns:
Total linear k-weighted power of all channels. 0 if AK_EnableBusMeter_KPower is not set (see IAkMixerPluginContext::SetMeteringFlags() or AK::SoundEngine::RegisterBusMeteringCallback()).
