Here's an example:
I'm not sure what is the usefulness of that ability to encode full spectrum for a brief moment. Or perhaps it's an error.
Very strange. Could be a glitch.
It happens to a lesser degree on most of the snare and hi-hat sounds. You can see a little spike that goes 100-500 Hz above the usual limit. Those smaller spikes on transients are also visible in that image i sent in the previous post.
I checked that same video and it didn’t do that at all.
Maybe it’s not on the encoding side, but a YouTube decoding glitch?
Or maybe that specific bitrate version file which was on the closest server to you had glitches?
Has anybody tried tests with YouTube premium?
Could be that only lower quality audio is available for free.
It doesn't do that spike all the way to the top more than once or twice in the whole video. The smaller spikes of +100-500 Hz happen frequently.
No, I’m not paying for YouTube, but I suspect that may be the problem here.
I was asking if someone here is paying for YouTube premium and if they could test to see if it gives them the full frequency range.
Found this online:
“ YouTube currently streams in 128 kbps ACC, when you select the Normal quality.
Premium subscribers can also select the High quality, which streams at 256 kbps AAC (equal quality to GPM's 320 CBR kbps).
To save bandwidth, you can also select Low quality with 48 kbps HE-AAC.”
Interesting. Unfortunately in Tube AU I do not see an option to select the video quality. I haven’t paid for luxury youtube though.

Thanks 🙏
I usually use Izotope RX To generate test signals. It has the same problem: at the beginning and end of the signal there is a click. I have to crossfade if I don’t want to see that in the spectrogram. We are planning to make a sine sweep app. I’ll make a note to fade in and fade out the sweeps in that app. I think test signal apps usually don’t consider this issue to be important
It can be done by adding a fade to the beginning and end of the test signal. But that workflow may be somewhat inconvenient
That one is real
DualVCF sounds amazing after the update.
Best filter on iOS.
Do guitarists care about digital aliasing as much as producers who mainly use virtual instruments?
I try to make my virtual instruments sound like my favorite actual analog synths and drum machines avoiding aliasing as much as possible.
With guitars/vocals, is aliasing acceptable, because there is no doubt that the source is real and no need to fool anybody?
Digital aliasing sounds bad on guitar unless one is intentionally going for that sound. Aliasing avoidance is something the best amp/distortion sims do.
I care about it. But I have never seen a digital guitar amp sim that doesn’t have aliasing. For synth oscillators there are well known techniques for keeping the volume of the aliasing noise below the noise floor but for guitar amp and pedals driven to high gain distortion there are no such methods. Mainly for digital models of guitar amps and pedals we use oversampling to reduce aliasing noise and that helps a lot but to get the aliasing noise all the way down below the noise floor we need really high oversampling rates. Distorted guitars sound so noisy that it’s often reasoned that aliasing noise is well masked anyway so it’s not necessary to totally avoid aliasing.
Thanks for posting this one @jolico, I hope people will take the time to watch and understand the subject instead of arguing about numbers, oscillographs and spectrograms 😉
Watched all of that and learnt a lot so thanks @jolico The quote from the video ”Consumers mostly don’t care” is something I like to remind myself when trying to achieve that last x% towards perfection.
I tried it with the free period, just to see what difference, if any, it makes to use it without the ads. Suffice it to say I kept premium and don't ever want to go back
if you use YouTube regularly it's... how we say it around here... got it, it's a game changer
Just remember to get premium through a browser first.
Don’t get it through the iOS/iPadOS apps, because you will pay an extra 30% every month for Apple’s cut.
You can get the family package instead with that 30% extra by starting the subscription through a browser.
@jolico <> these are great...really appreciate the posts . if you have the app MixBus..would love to see some of the compressors/hardware emulations put through. Also the recent Schlap and Smoov comps if you have them.

It would be soo so amazing if we could export these images as jpeg or png
