ADAU1451 Read abolute Volume function

Dear Sir,


     Would ADAU1451 can provide the function to read absolute volume (may be linear 0~1.0, or dBFS: -96~0)?


For our customer's project, they use “Signal Detect” and output result to “Readback”.

Then they want to try “Readback register address” on XXX_IC_PARAM.h,

but the disadvantage is, “Signal detect” only report signal on/off, not absolute volume.

If we could get "the signal absolute volume", how to implement it?


Thank you!
