In lame there is an option -q which stands for algorithmic quality and if we set it to 0 the produced mp3 file is of highest quality
When I try to play these poor quality opus files in AIMP player(android) I am unable to hear what the person is speaking and instead I am hearing noise like shhhh garrrr and other electronic sounds.
