A-weighting / C-weighting filter

Hello,

 

I am thinking about implementing an A-weighting and an C-weighting filter into a ADAU1701. In a previous version of a project I implemented these filters in the analog domain. For the next revision I am planing to transfer them to the digital domain. The response will be more accurate and not sensitive for component tolerances.

 

What do you thing is the best way to implement? Combining various Filters or using FIR or IIR. Maybe anyone out there has done this before and likes to share his experiences. Or is this for some reasons not a good idea to do this.

 

Thanks for sharing your thoughts

Regards

Bernd
