Zoom classes: 2kbps

Just the jump from 32 to 64 is so drastic.

The jump from 32 kbps to 64kbps was so drastic. I could hear the differences insanely clearly

Just so you all know KZfaq automatically compresses uploaded audio to 128 kbps So 256 kbps audio in this video will be same as 128kbps as well

If you don't notice any difference between 128 and 256 it's because KZfaq limits the audio quality to 128 Kbps to every video

0:13 16 kbps 0:38 32 kbps 1:06 64 kbps 1:34 128 kbps 2:02 256 kbps

But KZfaq also reduces the quality of video and audio, that is, the audio that is playing is also compressed. 😂

Fun fact I watched this video in 144p 😂😂

16: lots of missing details, u hear its compressed 32: u get some more detail, but u also hear they are compressed still 64: whoa! high! some "pinches" still blocky tho 128: now its sounds 'clear' 256: there now u have hard time to decide or notice

Different people have different opinions on what sounds good based upon how well you can hear, and the quality of your headphones. With my cheap headphones there is barely a difference between 64/128/256, but if I plug in a high range set of quality headphones the difference is pretty dramatic. This is exactly what I needed to determine the bitrate to encode for my kid’s cheap headphones, 64kpbs all the way! 😁

Perfect example of the different bitrates, really helps out!

Doing this same video with audio from a live band with some light vocals would really help over digital audio. As you could get the highs from the cymbals to lows of the kick drum, and the warm mids from a vocal accompaniment. Nice video though.

I can totally feel the differences in this audio, awesome

Thank you very much, coz for all these years, I didn't know the difference between each

Wao Nice👌👌 After this listening this music in Spotify and that was awesome sound quality,in Basic mode it was More than 256kbps 🔥🔥🔥

Legends are watching this without Earphone 😂🤣

Do keep in mind that thus can vary WILDLY depending on what audio format you use. OGG Vorbis and Opus can encode audio in very low bitrates but sound like 192 - 240kbps still. Their compression algorithms are extremely clever and well designed, able to shave off a lot of bits with no audible loss in quality. I’d love to hear a comparison of those tbh.

THANK YOU SO MUCH SIR 🙏🙏🙏🙏🙏🙏🙏

Super . Thanks !

for my own reference 0:13 16 kbps 0:39 32 kbps 1:06 64 kbps 1:34 128 kbps 2:02 256 kbps

first big difference for me was from 32kbs to 64kbs the quality and clearance of the audio is big imo

Thanks for this video!

Thank you so much for this video 👍🏻👌🏻✌🏻️

you can clearly hear the diffrence upto 128kbps but 256 sounds exactly the same because youtube audio bitrate is locked at 128 max , I think it would be better if you would include a link or a site so we could really hear the 256kbps bitrate or even higher if you gonna do that in future , anyway still a good video :)

Since recovering from my traumatic brain injury in 2018 the sound perception of my ears sounds so different. Since there is a hole at the right side of my head. The quality of sound of my left ear is different from the quality of sound from my right ear. I found your video today(nov. 14, '22) and I have never been happier(since Im testing my new headphones) Thank you for making this and for existing I hope you have a great rest of the day 💃😘

Thank u very much It was very useful to know the differences nd really well made 😊❤️

I have learned the hard way when i started dj -ing to never use anything below 320 kbps 😅. Now i use flac amd wav files which easily range from 800 to 1780 kbps. ..... crisp sound, i tell u😊😊😊😊

Wow, it's amazing.i mean there is very big difference in 🎶🎙️. here quality is matter that which is the quality of our music

You will feel the difference in the higher frequencies, so you gotta have good tweeters to tell the difference. The quality also varies from one codec to another (for example: 64kbps sounds horrible in MP3 but it's great in OPUS)

Thanks for video 🙏😊

Cool to hear. But also important what your DAC can do and maybe software and components likecapacitors etc are capable of. Also what headphones… boy the list goes on and on XDD

Why this video is so underrated? It should have had more than a million views till now❤️

For additional insight: I have the excellent equipment. It’s all perfectly placed. All the room correction is setup. The room is dedicated for A/V. SACD, Blu-Ray Audio, DTS disks, Atmos Blu-rays, streamed MQA, etc. I can tell a good recording / production from a bad one. I can usually tell a remastered version from an original track. I cannot tell high/low bitrate past ~192. I’ve done enough A/B testing across codecs, media formats, and streaming to have proven this to myself.

Old day's back to listening to this song ❤

Sort of like when you watch an ad for a high definition TV on a standard definition TV

there is more separation between instruments the higher you go. awesome video!

Good video. I think it would be a better demonstration with acoustic music or Classical. Our ears know what real instruments should sound like but electronic music could be anything.

Uhhhh, nice video 😁 Thanks!

the tranformation between 32kbps to 64kbps is insane BTW love your work and effort on this video.Appericate that😊😊😊

Thank you! I learned more😊

There are some online tests which give you lossless vs compressed 128kbps audio files and I always fail to detect the lossless one. I don't get how some people can "definitely tell the difference", but that just makes it easy to blame it on my audio setup.

Really Helpful. Heard the difference 🥂

Some genres get hit harder by compression than others though. In rock music you can lose a lot of detail in drums or guitar power chords when there's not enough of a sample rate. (Basically when there's more going on at the same time.)

one of best explanation,no words needed

Awesome 👏

Ikson's music getting more and mmore exposure ^^

16k 32k 64k 128k 256k 0:24 0:49 1:17 1:45 2:12 0:24 0:49 1:17 1:45 2:12

This video was so inspirational!!!😃I hope other people enjoy this like I did!😍😍

Amazing 😍

I can feel the differences, well-done 👏🌷

Excellent work!

Sound quality becomes so great and real-like at higher frequencies.

Funfact: YT Has limit to 128kbps

Thx for information this was what I need.

I remember in 2006 64 kbps was enough for me, and still in 2022 I feel okay with 64 kbps 👍🏻

Muchas gracias, exelente,saludos desde honduras

Good👍👍

Really cool to see how far audio quality has come!

I think you should've used a song with higher pitched synths or strings/horns for a better comparison in 128/256. It is pretty hard to tell the difference without many layered, you need a good ear for details but it becomes pretty obvious when high strings sound a bit pitchy or compressed. Then again, I guess depends on how well it is encoded to begin with.

Aunque la calidad de audio esta limitada por KZfaq no suena realmente a 256kbps y para que suene a esa velocidad necesitas reproducirlo en YT Music que hay puede reproducir hasta 320kbps y la máxima calidad que he escuchado es en 1024kbps pero si tienen un audio en esa calidad y unos parlantes con esas características se escucha real es decir que si reproduces un ruido como hablar y lo pones se escuchara como una persona real, al igual que las pantallas OLED que tienen una imagen real y negros perfectos es decir obscuridad totalmente sin que se vea nada de luz de la pantalla, mientras mas calidad mas cuestan los equipos pero mas satisfactorio es

Very Good Thanks

64 kbps, и тут сразу вспомнил моё прошлое, моё детство с моторолой Е-398, почти все песни были с таким качеством:) но по тем временам это было круто по сравнению с Siemens у которых были Vav с диктофона :) я прям ностальгирую :)

It should be also noted which codec is used. This seems like MP3 codec (most widely used), which frankly isn't the worst codec, but definitely not the best. For some reason it's most popular tho. If you did the same comparison with Opus (probably the best and most efficient codec so far), results would be vastly different.

64kbps used to give some good enough quality to enjoy music back then where storage was a big issue

From 64 kbps it starts to sound nice

i feel like the differences lies in the highs and lows the more bitrate the better you'll be able to hear the bass notes, and very high quiet notes

idk why this is in my recommendation but im glad it is

Thank u!

Good example with a somewhat layered mashup.. perhaps the difference will vary a bit depending on the complexity of the original recording?

Bro 16kbps isn't that bad lol I still remember listing to radio in my Nokia when I got new keypadphone which has SD card slot in it, it was joy man I can't describe that That good old days

Lol KZfaq doesn’t supports 256kbps, you’re fooled 😂

Good Job

16Kbps audio makes me feel like I'm hearing one of those ringtones you'd buy for like $3 on your moto razr

First, I was on iPhone with the standard Apple earbud, it was no difference between 128 and 256. So then I moved to my PC with a K-5 Pro DAC and AKG K257 studio headphones and BAM! Still no difference. I'm pretty sure that you need a track with more instruments covering from the lowest to the highest dynamic range to tell the difference. -12dB lowpass to +12db highpass. The track being played in the video doesn't have enough information. People who say they can tell the difference between those two must have superhuman hearing ability or out-of-this-world audio devices, or simply are victims of the psychological effects.

After using headphones 🙃 The result is mind blowing I can feel the difference between every layers of sound quality Except the last one 🕜

32 to 64 and 64 to 128 was the biggest difference imo Unfortunately youtube doesnt allow for even higher bitrates, so 256 will sound the same as 128 here

KZfaq playing the audio @128Kps peak 💀

Thank you ❤️❤️

Very good illustration, thanks.

It depends on codec. Mp3 is quite old, there are more modern codecs that provide much better quality at the same bitrate, e.g. Opus (used by KZfaq) or AAC+.

Simple but in detail new sub

Thanks bro give such a knowledge

At the end you need to go back and play the 16kbps and the 256kbps to contract the ranges.

Tnx bro very helpful video I can't understand difference between 32 kbps audio to 256 kbps song without watching this video...

Since KZfaq always caps any audio bitrate to 128, there's no difference from 128 to 256. The the other ones, do show difference from 32 to 64 and from 64 to it's double.

Great video

When I used to have the iPod, I used AAC format 128 kbps (that was the standard at that time), and it sounded awesome! I could not tell the difference between that and the CD

and school will still use 16kbps audio 💀

We need a bit depth comparison 24 bit vs 16 bit vs 12 bit vs 8 bit vs 4 bit vs 2 bit! 😊 Unfortunately all of this has to compete with KZfaq's own compression over the top - be good to have a link to a WAV or uncompressed master file for comparison.

❤️🔥

For all those wondering about the audio bitrate. According to JDownloader 2, this video has: 192kbps aac (h264 mp4 version) / 160kbps opus (VP9 webm version) / 128kbps aac (VP9 mkv version) / 64kbps opus (another VP9 webm version). These stats are for 720p resolution. For every other resolution (1080p / 480p / 360p / 240p / 144p) the stats are: 128kbps aac (h264 mp4 version) / 160kbps opus (VP9 webm version) / 128kbps aac (VP9 mkv version) / 64kbps opus (another VP9 webm version). Even when I choose 720p resolution, youtube plays the OPUS (251) audio codec on my computer, which I think It's 160kbps. At this quality I can barely notice a very very very slight difference (if any) in the highs from 1:43 (128k) to 2:11 (256k) when playing one part just after the other. (Playing downloaded AAC 192kbps audio track, it sounds exactly the same as the opus 160kbps track playing through youtube). 16kbps lacks highs and detail. A lot of "clipping like" noise when too many sounds play at the same time. (Limited to about 8KHz bandwidth or even less) 32kbps lacks highs and details. A lot of "clipping like" noise when too many sounds play at the same time. Sounds like the very same crap as 16kbps to me. (Limited to about 8KHz bandwidth or even less) 64kbps has more highs. "Clipping like" noise almost completely gone when too many sounds play at the same time. But highs still sound a bit robotic. A huge improvement over 32kbps. (Limited to about 11-12KHz bandwidth) 128kbs has a little bit more highs. Highs are clearer and sound more natural. A good improvement over 64kbps. (Limited to around 12-14KHz bandwidth, but it never reaches 16KHz) 256kbps almost indistinguishable from the 128kbps version. At least for me in my 40s with my just one step above crappy headphones / speakers. (Limited to around 12-14KHz bandwidth, but it never reaches 16KHz) (Bandwidth according to AIMP 3 player 18 band spectrum analyzer playing the aac 192kbps track)

Thanks for the test!

The most impressive and entirely surprising thing about this entire video is just how good the 16 kpbs stream actually sounds. I was expecting it to sound horrible, but it actually sounds remarkably good. I think that's just a testament to how good digital audio really is today. Sure the higher bit rate recordings sound better and unquestionably have more dynamic range to them, but even at 16 kbps there is more than enough sound quality and fidelity there to be able to completely enjoy listening at that level.

Unique and creative content. Worth it bro.

Very nice 👍❤

o oke :)

isn't KZfaq capped at 128Kbps?

I really had not any idea about that 😸😁 I think all are same in childhood 😁

Very helpful
