The Nokia 9 pureview is making static on the recording when I speak into it, but the other side is clear.

Please help

Are you recording calls via a headset? Some phones have bugs in the ROM related to headset.
If you root the phone, Boldbeast Recorder can fix it at once.
If you don't root the phone, there is no solution in the market. You have to wait the manufacturer to fix it in future ROM updates.
