How do I know the output level in dB?

Is that a public API we can use?
I searched here before asking my question.
The reason why I was testing FMOD_DSP_METERING_INFO and FMOD_ChannelGroup_GetAudibility() was, I thought we couldn’t use FMOD_DSP_TYPE_LOUDNESS_METER after reading this and this answers from your team.
