44,1khz is not the standard anymore. it’s 48k. (since music and movies are primarily consumed via streaming)
it‘s also the most compatible samplingrate for those two mediums.

by the way, YouTube's maximum audio quality is 24 Bit 48 KHz
Regardless if you have YT Premium or not
@williambreeden4805 Says:
320kbps MP3 for me. High quality, good compromise with file size, and plays EVERYWHERE. A format does me no good if my device or car head unit won't play it.
@DeeBellwether Says:
clear and well stated explanation, i expect to retain what i need in the immediate.
thank you!
@mwgary Says:
FWIW all my audio cd collection and cd audio books in ripped to wav format. These days high capacity disks space is relatively cheap to not need compression. If I need to put onto a media player, I can compress at that time the files I need.
@CSGraves Says:
Been pronouncing .wav ''WAVE' for 30+ years, so hearing it referred to as 'WAV' is breaking my brain. Flashbacks of the jif/gif controversy

When I got my first iPod Classic to store downloads on instead of burning them on to CDs I used ALAC. Now I use ALAC just for CDs on the iPod and for downloads I use FLAC.I have a Sony Walkman NWA-55L DAP for listening to various formats including FLAC and ALAC stored on 2x1TB microsdcards and various back-up HDDs for all my media folders,TV series,Films,Music Videos and Music. With the price of storage HDDs getting cheaper all the time I don't worry about the format sizes anymore. If, when I am listening to music it is a MP3 I try to replace it with a FLAC. The MP3s are usually remnants from when I first started to download music.

5:05 to all the people who cry about gif's true pronunciation being jif and not gif, i dont hear any of you saying wôv but rather wahv or wave

god i love your videos. i didnt even know i needed this video. but im glad you made it. keep these types of things up. especially 256 vs 254 vs "yify" movies found online or on bluerays
@sxyqt3.14 Says:
hey there your channel is a treasure. could you do a 2025 version of a video on how to encrypt an external hard drive please?
@radiogalway1636 Says:
I rip to Flac, uncompressed.

Well done video — thank you for putting it together !

There's a ton that you missed: https://en.wikipedia.org/wiki/Audio_file_format
@Florianski Says:
The Opus Codec is truly magical. You can encode with around 100-120 kb/s and it sounds absolutely undistinguishable from the lossless source file, even if you listen on high end audio gear.
@SteepSix Says:
I have no issue with 320kbps MP3 and my audio collection is mostly just that. Lately tho I've been considering M4A and FLAC as I do detect a quality difference - however small... Truly tho it really has always come down to convenience; What will play on anything? MP3 for audio, and now MP4 for video, has become a universal standard... You can confidently give either of those file types to literally anyone and know they will work whatever device they're using to access them. This consideration has always come a very close second to quality, and has sometimes overtaken it.
@suchyraz Says:
😁
@CaptainDangeax Says:
The most important thing is, can my player play the file? The common is mp3. So all my playlist is mp3
@2handsome398 Says:
I use Flac for archiving cds, MP3 for everyday use, and Opus for speech heavy things like audiobooks.
@emuhill Says:
I went with TTA for lossless audio. It produces some what smaller files than FLAC. Although it probably doesn't have much of a future.
@tommik1283 Says:
The worst format ever has to be Monkey's Audio. Ridiculously slow codec, so inefficient. Thanks god is more or less dead today... Long live FLAC!
@radornkeldam Says:
Lossless audio formats aren't really about "sound quality". They just compress the original digital audio signal so that, when decoded, the output stream (be it PCM, DSD or whatever), is bit for bit identical to the input. Of course this implies perfect quality as there won't be any difference between the losslessly compressed file and the original uncompressed stream. But when testing the results of lossless compression, you don't go and listen to the file to check it's "quality", but, instead, you just use a binary comparison tool on the decoded streams, similarly to how you can diff any file. There's no high or low quality when it comes to lossless codecs. They either are lossless or they are not, in which case they fail in doing their job. A single inaudible 1-bit difference in the least significant part of one sample means it's not lossless and thus, it fails.
Lossy codecs, on the other hand, are the ones concerned with "sound quality", as they are modeled and their encoders tuned to satisfy human perception in a number of ways, and the extra data they can shave off compared to lossless compression is based on working with the shortcomings of human hearing. They are PERCEPTUAL, and the way you assess their "quality" is indeed with by listening with your ears (or those of experienced listeners, for that matter).
There are two aims here. The highest possible goal of a lossy codec is complete transparency, meaning that a human hearer should be unable to PERCEIVE any difference between the original signal and the lossily compressed one even in a double blind (ABX) listening test under ideal circumstances (quiet room, no external noise, good audio equipment, trained ear...). This may be achieved with a well designed format and a well tuned encoder provided with enough bitrate to do it's job.
In practice this doesn't affect the average music listener, so for lower bitrates the goal is usually not total transparency, but achieving enough fidelity for a wide range of audio signal types (speech, music, AV soundtracks, etc) and music genres (rock, classic, electronic, etc...) in a way that, although may fail to achieve complete transparency, at least won't be too obvious or annoying to the listener, like introducing flagrant artifacts or muffling the sound too much, etc. So there's not just quality levels, but quality types, the highest being complete transparency and then, under that, a range of levels of transparency and pleasantness.
@radornkeldam Says:
I don't think FLAC was initially released by the Xiph Foundation, but, rather, it was first released independently, and, later, the project was adopted by Xiph and they took over maintaining it.
I certainly remember using FLAC before it became part of Xiph, and later seeing the anouncement about it becoming so.
@lap456 Says:
Just saw the video; I didn't konw you looked at video codecs and files alreday. I must have missed that video since it was mixed in with over 100 more not let wathced videos. The Blu-ray video on DVD-R thing I give is do that iade of codecs not always fiting the file types. Hif is like jpeg but holds more photo data. Dot CDA is just what computers show ecah track on an Audio CD since Audio CDs have no ture file system. CD-Rs have an file system used by the burner to keep track of where the data goes on the disk. This is how the Sony Palystation konws an boot laged game is trying to ran. Since the CD-R disk is missing the codec that the Palystation looks for.
@Foysalispbroadbandmetrowifi Says:
I am using FL STUDIO and PC 192KHz for my Music Studio, Layer 6 Audio presentation layer. Also this Linux RHEL 192KHz Audio, Thank you so much.
@lap456 Says:
Yuo may what to do one of video formats since riping an Blu-ray Video disk with Make MKV is alot like riping an Audio CD with an app like ITunes. Also trying to paly an AVI file coded in Divx using an tool that dosen't understand Divx has no iead on what to do. It's kind of like burning an DVD-R in format used on Blu-ray Video disks. Only an Blu-ray player cound read that disk eventhough it's an DVD.
@devarionarias Says:
This video is a great explanation of how all these file formats work and what they are. I've been working with many of them for years and still learned a couple of new things. Thanks, Chris!

5:21 that sounds like it was originally created for OS/2.
@rfvtgbzhn Says:
Bit depths above 16 bits are just a waste of space for a finished audio file. 65,536 levels is already way more than what the human ear can distinguish.

When I got my 1st computer, everything was just wav. Simple times.
@robumf Says:
What most people don't consider is the quality of the speakers that is being use
If you using pore speakers like what was being used on transistor radios and many cheap electronics. Surprisingly you can get by at 32 kbs.
After realize the simplest DVD has register and you can apply math, including a random generator
As an experience I place 25 hours of music on a 8mb DVD brought the video to 1mbs except for menus for video and using MPEG-2 48kh.

While the content is obviously a grown up level of complexity, these videos give me a strong vibe of sitting cross legged on a primary school carpet watching a video tape on a crt tv on a trolley. It feels nostalgic and I love it
@Jonius Says:
Also didn't cover CBR and VBR for bitrate, but I guess that's not a file format thing
@Lothyde Says:
Mp3 shouldn't be alive today, it's obsolete. The quality of mp3 at 320kbps is comparable to Opus at 160kbps.

Chris... serious question, did you stop aging like 10 years ago?
