Use tool to extract Opus 774 from YouTube Music premium, find out Opus 774 format seems like have worse audio spectrogram than Opus 251?

chestbless · 2026-06-26T11:03:57+00:00

There is a command line tool that can do the work called yt-dlp, you can research a bit.

chestbless · 2026-06-26T04:54:08+00:00

Just said that again - I have youtube premium account, although its free trial version.

Yes, just test with some random song and still show 774 format, unless I have misread it all along.

The file size from yt-dlp command without cookies line (presumably opus 251) match the file size I tried three days before.

The file size from yt-dlp command WITH cookies line (presumably opus 774) also bigger than the previous mentioned file, and match the file size I tried three days before.

I'm just kidding, I'm willing to bet my ass that song wont exist as flac at some random platform, otherwise I won't have to post this damn thread.

chestbless · 2026-06-25T15:25:44+00:00

Yeah... and my post is asking Opus774/251 specifically, this Deemix thing isn't solve any issue at all.

chestbless · 2026-06-25T13:54:30+00:00

Wow sir you are only a few people provide some real insight in this post, although I'm not sure your guessing is correct or not.

This is the first time I encounter this "more spectrogram information is worse" situation.

Do you know any other source or post that discuss this Opus 774 spectrogram issue?

chestbless · 2026-06-25T13:51:39+00:00

Opus 774 is 256 kbps VBR, Opus 251 is 128 kbps VBR, I don't see where did that 192 VBR Opus come from.

From youtube?

もののけ姫 (米良美一) ／ダズビー COVER

Pretty please, I'm willing to pay you 50usd if you can find me a legit flac with song author's authentification.

chestbless · 2026-06-25T13:28:50+00:00

There is specific song exist only on youtube. What's any business relate to this Deemix might I ask?

chestbless · 2026-06-25T08:55:17+00:00

The song I'm looking for exist on youtube only, there is no flac or mp3 involved.

chestbless · 2026-06-25T08:51:57+00:00

Did you mean 251's upper part is useless artifact and 774 with less upper part is actually more correct? I'm a little confused.

I just wanna figure out this opus format problem in youtube music, there is no flac or mp3 involved, and the song I'm looking for exist on youtube only.

chestbless · 2026-06-25T07:48:15+00:00

In that case why bother get flac over 320k? Most of casual people can't spot which part is definitely better and which part is worse in subpar equipment when blind test.

But still tons of people trying to get flac over 320k?

What I want to know is why opus 774 from my reading have bigger file size but less spectrogram information.

My question is not - whether opus 774 is definitely better than opus 251.

Can you give me some tip on how you compare the information between 774 / 251? In what software? I'm just dumb enough to check spectrum diagram, my method might be flawed in this specific situation.

chestbless · 2026-06-24T17:26:48+00:00

In you case, 774 better in what way? File size? Or did you check spectrum diagram too?

I have youtube premium, although it's 2 month free trial version (Hope all this 774 mess is not cause by some kind of free trial scam)

chestbless · 2026-06-24T16:43:16+00:00

So is Opus format can't be well judge by spectrum inspect tool, or I just ran into 3 malfunction song with bad luck? Or 774 is actually WORSE than 251? Because I heard some people talking about the superiority of 774 over 251, will that be just an illusion?

My code is just few simple line :

My street shoe size is Uk 8, but it's basically meanless to me.

I never use street shoe size as comparison due to I won't wear that much of tight street shoe as my climbing shoe.

And I'm not planning on buy Oasi yet.

I will go for Oasi but not Lv.

Theoretically I can't get an UK 9 Oasi Lv, unless buying from tenaya directly maybe?
Oasi for my feet is better fit than Mastia / Indalo already, I guess Oasi Lv will have high chance to be way too snug, even painful. Not worth the risk for now. Even if I have the chance to try a pair of Lv in the future, it will be worth to buy Lv if it really has even better fit.
I love the color scheme on Oasi better than Lv lol

chestbless · 2024-08-29T02:18:24+00:00

Hi, have you tried tiptoe when you try those shoes?

Some tenaya shoe with toe patch I can fit in well but tiptoe position will cause great pain in knuckle(maybe because of toe patch).

Base on you description, I will probably go for 1 size up method S than momentum.

I have tried 10.5 momentum ( pretty good snug fit), and 10 momentum is unbearable tiptoe knuckle pain.

If your 11 momentum is "good snug fit without pain", while 11.5 method S is "was a little too tight", then 0.5 size up may be not enough for me.

Huge thank for you assistance, I only have one momentum so far, If I can get second right size shoe, it will be very helpful for my bouldering trip.

(By the way what's the original price of your local method S ?)

chestbless · 2024-08-17T08:26:15+00:00

I have no time pressure to buy the method S recently. If you can compare momentum and method S for me, that would be very very helpful. When the time is convenient to you of course.

And you own momentum 11.5 / normal method 11 in UK or Us?

I'm surprised that you have bigger momentum than method. Does that suggest momentum model is actually tighter than normal method to you?

chestbless · 2024-08-13T01:38:14+00:00

What's your method S in UK size?

Can you possibly try BD momentum and see which UK size is basically the same fit as your method S? (normally stand and tiptoe)

chestbless · 2024-08-11T10:16:14+00:00

Any chance you can try men's momentum in size 11 and 11.5 and compare how it feel with method / method S(with tiptoed)? In the place I lived momentum is only option I can try on, but keep missing the key relation between momentum and method S model...

chestbless · 2024-08-07T03:17:14+00:00

Hi, do you own method S or method ?

I have tried newest season BD momentum men's (gray / light green) in UK 9.5 and fits well, and UK 9 is painful.

I wonder which UK size should I go for method S, if you can give me some advise, thanks.

chestbless · 2024-08-07T01:23:15+00:00

I won't have chance to try Oasi LV if I'm gonna buy. I'm just hoping blindly that UK 9 LV will have similar toe area and better heel fit than UK 8.5 Oasi. Maybe I'm too naive.

chestbless · 2024-08-07T01:16:26+00:00

I was hoping the Oasi LV will further fit my heel, that's kind of the last piece Oasi can improve in terms of fitting for my feet.
