Hi Amey,
Dunno if you are asking for advice or is it Laura. Anyways, the best bet 
would be to use ffmpeg as it already has support for transcoding and is 
now in debian.

As can be seen both libtheora and libvorbis are good there. A handy way 
to start would be https://trac.ffmpeg.org/wiki/TheoraVorbisEncodingGuide

Also see https://flossmanuals.net/ogg-theora/encoding/vlc/

Although the last word on this is and always has been 
http://forum.doom9.org/ where they have been playing with transcoding 
for over number of years.

For deleting noise and enhancing audio, the only tool I know is Audacity 
(in free software) and this is the way you can go about it.

If somebody wants to add something, they are welcome to do so, maybe 
Vikas as he's also played with free software and audio quite a bit.
