Is is possible to extract certain audio tracks from bluray?

There is a quick clip that I want to capture, but there is a lot of background noise. Is there any way to get the audio tracks to grab the clean version?

You can use mkvtoolnix to break the particular audio track out from the whole MKV file, but it will be the "whole" audio track in most cases. Getting individual sounds out would depend on your other tools.
