separate weighting for SPL and RTA please

[James King]

I would find it very useful if I could use A-weighting for the SPL meter while keeping the RTA completely flat. I'm an audio engineer using this app at concerts and it's useful to have the A-weighted SPL meter, as this is the weighting most audio engineers are used to (like, I know how loud 98dBa is), however I need the RTA to stay flat so I can correctly see the frequency range of the audio I'm mixing. being able to do this would be extremely useful, currently as it's more important to me to have the A-weighted SPL meter I am living with A-weighted RTA but this means it doesn't really give me any useful sub bass information
