I do not particularly wish to re-encode but what I am doing is extracting the audio and saving it within my music library on NAS which is then served to my LAN and used by various renderers. I have two objectives, not to degrade signal further than that available on Youtube and to save the result in a format that works with my music system.
I have in the past had issues with .m4a but can try again as it has been a while. I am always suspicious of using terms such as "best" because it is not a defined term but a subjective one. If I go to mp3 then my concern is that I may be further compromising the quality. I believe the sound is encoded as AAC in the Youtube. If I am correct then which format sticks most faithfully to AAC and will work with my systems. I shall do a few tests following your reply and see how I get on.
