Hope it helps Amber… Audacity filters/noise removal you need to run through that twice:
!st time you run the filter you select three seconds or so of ambeint noise, then
you select the whole file, go to the filters/noise removal tool and apply the effect to the whole selection…
not very intuitive, but once you figure it out it is easy enough.
also… do not overlook the soundproofing of the car doors and thicker carpets/matts in the car… any car audio installer should be able to show you the best sound proofing materials to buy… (some cars are very noisy others are not, so you decide)… adding sound proofing is not that hard……
