Dynamic loudness in 1701

Hi,

I am looking for a way to apply dynamic loudness to my signal in ADAU1701. I have found the dynamic bass boost block but that only adds gain to the lower frequencies. I want to add a dynamic "Fletcher Munson" type loudness curve which includes both low and high frequencies.

I have found the loudness block which adds gain to both low frequencies and high frequencies but this is not dynamically controlled.

Please let me know if there is a good solution to this available!

Best regards

Markus
