There is a way to add some audio filters to Hybrid?

[Bartoloni]

i have a lot of VHS that have a small high pitch noise from the camcorder motor... and i can easly remove this on video editing..
BUT... it's possible to add an audio denoiser to Hybrid just to not "touch" again the footage after the compression?

or i need to use FFMPEG before hybrid to remove the noise.. and after this step use Hybrid?

Thnak you in advance for any help
