"You should NOT convert to mp3.\n \n\n\n\t \n \n\n\n\tYoutube serves you video and audio in various formats.  For video, it uses AV1 or VP9 or H264 codecs.  For audio, it also uses multiple formats, but mostly AAC and Opus\n \n\n\n\t \n \n\n\n\tAs you can see in the picture below, for that LinusTechTips video, the downloader I suggested gives you the option to save\n \n\n\n\t1. M4A -  AAC in MP4 container - so you download a M4A file, which is a mp4 file with just audio\n \n\n\n\t2. AAC in the AAC container, raw aac  - you can open it with music players like foobar2000 or media player classic home cinema and it just plays.\n \n\n\n\t3.  Opus audio in OGG container  - opus audio is better than AAC and it's open source codec\n \n\n\n\t \n \n\n\n\tYou can mix these formats with your video with a tool like  MKVToolnix for example. \n \n\n\n\tAnd a lot of video editors can work directly with m4a audio files, or even AAC files.... AAC codec used in both is standard, very common.\n \n\n\n\t \n \n\n\n\tIf you try to convert to mp3 , it's like opening a JPG picture and saving it again as JPG - you pointlessly lose some quality.\n \n\n\n\t \n \n\n\n\tIn the picture below, if you want to download just the audio, you can simply delete the video track and the application will download just the audio and the rest (close caption text ) if you leave them for download.\n \n\n\n\t \n \n\n\n\t\n \n\n\n\t \n \n"
