About ADAU1467
Hello, I want to ask a question. In ADAU1467, can I read the data level value of this control? Or is there any control in SigmaStudio to read the data value of the input signal? Because I have a project that wants to get the data value after ADC. Thanks Reply!

The RMS calculation in the meter block is calculated on the PC host by polling rather than the DSP. Therefore, the value is not available in the signal flow. Below is an example of calculating the RMS level for use in an algorithm. The top path computes the value in dB, and the bottom path as a true RMS value. The square root in the lower path is avoided with logarithm math in the upper path. The gain of 18 dB compensates somewhat for the limited dynamic range that resulting from fixed point arithmetic.
