Missing documentation about audio quality

[nottux]

what does the quality level do? (like what is the specific quality selection at each level and is it 0 or 9 is the best quality?)

audio_samples.zip

files in it: work0.mp3 --> audio sample with option 0 chosen work1.mp3 --> audio sample with option 1 chosen work9.mp3 --> audio sample with option 9 chosen

as i look to codec information audio quality and size comparison was 0>1>9

Going to add this to the README soon, thanks for bringing this to my attention.

Marking this as solved as soon as I did so.

I think just putting it in the README will not help much for people simply using gydl (and not compiling it themselves).

How about renaming the dropdown menu items to "0 (Best)", 1, 2, 3, 4, 5 (Average), 6, 7, 8, 9 (Smallest). Also I would assume it's a good idea to default to 0.

I was wondering how to get the strings translated, but then I saw that the other strings in gydl.py are not translatable either and that there is a C rewrite available. Hope this is still fine :)

Thanks for the pull request! I'll later adopt the changes in the C-Rewrite.
