I have hearing issues and I cant hear any sounds above 900Hz so I would like to change pitch on sounds from 900Hz - 4000Hz to be at around 900Hz but if I use pitch change at like -75% then sounds from 1000Hz will go all the way down to 250Hz and the distortion will be so bad.
I know I could split the sounds having a track for 900Hz to 1500Hz and setting a pitch change of -30% another track for 1500 - 2000 and pitch change of -50% and so on.. But would be a lot of work and the result wont be as good as it could be, is there a better way to achieve something like this?
