Then codec with the biggest frequency range is the codec that provides the nearest reproduction value of the full frequency spectrum in comparison to non- compressed WAV with the range of approximately 22 kHz." Its shows when frequency cross-section of the codec leads to the loss of high-frequency part of the sound.

Transparency is the result of lossy data compression accurate enough that the compressed result is perceptually indistinguishable from the uncompressed input for the average listener."įrequency Response : "The analysis of the frequency spectrum of each song shows how well each code compression algorithm works in comparison to WAV and each other. Transparency : "A transparency threshold is a given bitrate value at which audio transparency is reached. I would not go back to AM quality now, but I don't feel like my life was any less complete for not having FM in my car as a teenager.īitrate is not the only thing to consider when it comes to codecs.įrequency response range is also very important. Even today, if I listen to an "aircheck" of an old AM radio station that was recorded off the air (in other words AFTER it had passed through the AM transmitter) I think that in some ways that music was more enjoyable, even as I realize that all the high frequencies are totally missing. They always seemed a bit "flat" and lacking in bass. In fact it's funny, I grew up listing to AM radio (because back then the regulators thought that FM should only be used for "beautiful music") and when they finally started putting popular music on FM, I didn't like it at first because none of the songs I liked sounded the way I was used to hearing them. Also, a lot of people listen to music using cheap earphones or speakers, so they aren't going to notice the difference anyway. If you have to convert to MP3 to play them, maybe consider switching to a modern player that was made in the past two decades.Įdit: not sure if -x f140 is the same as f140 -x which is what I have in my notes so I corrected thatīut it doesn't matter if you are using a media player that can deal with mp3 and other better known formats, but cannot play opus files. If your player can play those, you should just stop there and don't mess with converting them. Similarly, you get the untouched unconverted Opus in webm file when using the yt-dlp f251 -x command. When you use the yt-dlp f140 -x command, you download the AAC in M4A file from YouTube, untouched and unconverted ffmpeg doesn't even need to run. The Opus version might be slightly better than the M4A version, if the originally submitted audio was high quality, but for all you know the original file might be a botched 64k Soundcloud download with the high frequencies cut off. The audio-only bitrates YouTube chooses changes over time, and at the moment they seem to be choosing 129k for M4A and 128K for Opus (older YouTube music videos may have different choices available). YouTube does not make the file originally submitted by the uploader available for download so we can only guess what that was. If the upload becomes popular enough, they will add an Opus version in a webm container with a slightly different bitrate which was converted from the originally submitted file. What happens behind the scenes is that YouTube recommends its artists submit files as AAC in an M4A container and then converts all submissions to 128k AAC (LC) in an M4A container. When using ytdlp -F, you will see that YouTube presents Opus and M4A audio-only formats. If your player can play M4A, there is absolutely no reason to prefer MP3 over M4A. M4A is the upgraded version of MP3, created in the 2000s, with both improved compression and improved quality. You absolutely will lose quality converting any another lossy format to MP3. MP3 is lossy compression tech from the 1980s.
