I turned on an ultra sonic frequency device at 24k and my roommate ran out of his room freaking out. I told him there’s no way he can hear it and that he was super human. He got his ear checked and he could hear up to 26k. It’s really rare but some ppl can hear it. I can’t, but I know the dog above us can 😆

In a Facebook group I'm in I occasionally do some null tests to prove points. And it's surprising how many people will say something like "I prefer to trust my ears!", or "a null test means nothing!". And just the same way people will say they hear frequencies up to well above human hearing. It's crazy how people fool themselves. All the while well respected audio engineers will happily admit that they can pick the wrong file when asked to pick the wav over the 320 kbps mp3. A great way actually of determining who you will let your next song mix. Hint: it's not the one saying they can hear 25 kHz.

When I listened to the "Samplerates" video on my laptop, through a USB connected sound card and high quality earphones, I was unable to hear the 10 kHz tone, which you had cranked up. I was concerned about my hearing. So I went upstairs to my audio production PC with a proper audio interface. I was relieved I could hear it. I then did some testing with other frequencies with the REAPER sine wave generator. It's amazing how limited our sound cards can be. Even a so called "pro" sound card. Also, those very high frequencies (above 10 kHz) are very susceptible to minor location changes, if you are listening on speakers. I could move my head a fraction and lose the signal, then move a fraction more to hear it again. Good headphones, of course, makes it more consistent.

Now, I accidentally discovered a test that demonstrates the limitations of plentiful hardware like iphones etc when it comes to audio reproduction. I ran an app in an attempt to shut next door’s dog up, that app let you produce all sorts of frequencies. Result? Nothing. No effect on the dog at all! Yes the frequency swept up, but having used dog whistles in the past, I know the effect it has, and it is clear the whistling etc simply was not in the upper non-audible range for humans. The only comparable lack of effect, was with a deterrent device for cats leaving ‘messages’ in our garden, and one old snow-white cat walked right past, unaffected. I realised, it’s deaf. Very irritating. Lastly, thanks for the tutorials you have made, and yes, I actually love animals, but not their nuisance habits. In fact, one neighbour had a right go at me for having such a deterrent device on my property, complaining at the effect it was having on his dog. I tried not to laugh as I said ‘This one here? The one I have not had batteries in, except for the first week, because it points the wrong way?!’. Yes, people can imagine quite a lot, and I doubt I am exempt. Remember that ‘mosquito’ thing that shops used to disperse young children/teenagers? Our children heard it once when we were out and about, and we had no clue, it was audio-invisible to us as parents. That’s why I had to turn off my deterrent squeakers in the garden - they sometimes kept birds from visiting, and our kids refused to go into the garden, so that was the end of them. [EDIT The end of the squeakers, not the kids].

Joking aside, with all the various sample rates and arbitrary convertors in web platforms and hardware devices, it is a quite common mistake to misidentify aliasing for ultra-sonics. Plus there's so much misinformation around, even veteran engineers don't know how digital sound works... And of course, the cross-sensory bias plays a huge role!

Sat here with my 9yr old son playing him sine waves, just out of curiosity and most likely in the most unscientific way possible. I've played guitar professionally for over 35 years and drummers have destroyed my hearing, but my boy is 9 with perfect hearing, at least I think so. 15khz had him pissed and he got less pissed as the frequency increased. He couldn't hear the 20khz at all but was aware of 19khz. I would point out that I was just curious and that I didn't follow any method or guidelines, but he did know when I'd paused the tone. It was the strangest thing, watching him react to something that I was unable to hear, although I could hear the 15khz tone, and him looking at me going "can you not hear that Daddy?"

When you switched to Linear Interpolation and hit play it woke my dog up and he was very confused.

I would assume that the reason his ears felt pressure when that part of the clip played is because he knew he was about to have to listen very hard to that clip and would subconsciously strain his ears to hear better, causing a physical reaction in his ears. like when you move your jaw and your ears pop sometimes, or when the pressure changes slightly. if you think you're about to have to listen to something extremely hard to hear, you're probably causing a physiological reaction yourself when you try to listen hard.

I'll try to keep my example short: Say I'm doing dialogue for a film, I have tons of mono items across tracks with their individual fx, and they all go to the dialogue buss. Visually/organizationally, I'd prefer to use a parent track, but in this setup I can't put mono plugins on my parent. They will only process half the signal coming in. I could put them in a parent for organization/looks, then disable their master send, then create sends from them to the parent, from their ch 1 to its ch1 , then set my pan knobs to dual pan. I can then take ch 1 and pan it centre and I can then use mono plugins. I feel like most DAWs treat a mono signal (assuming pan is centre), as one channel of audio until you get to the hardware output then it's split and sent to both. Reaper seems like it does it already at the item level. Now all my mono plugins have a stereo version, but I still feel like I'm unnecessarily processing 2 channels when one could do the job just fine and be slightly more resource-efficient. Does that make sense? At the very least it's a concept/workflow style that I have had to unlearn and adapt to the reaper way, and I feel like this is the one area in reaper that is like that, as it otherwise let's you appropriate it however it suits you :) Thanks for your videos.

In this case, both speaker and ear nonlinearity seem to be applied. Of course, I Know this test is a very artificial and restrictive condition. But Based on this, if the ear is a nonlinear structure Maybe be inaudible frequencies affect audible frequencies? Thanks for fast answer!

2 things i temporarily thought sounded better because they were "supposed to", until i realized later upon reflection with fresh perception that they were actually sounding worse than what i had been using previously: ik stealth limiter (mastered a couple albums using it and realized later it was way more distorted and less transparent than i had initially thought), and airwindows notjustanotherdither, which actually made masters sound worse than no dithering.

Cognitive Bias! sounds like a good name for a band??

I use pro L 2 but recently noticed that the only algorithm i like (modern) adds side information in low frequencies even when its all been cut previously in the chain. Any ideas?

When you modulate the gain of a signal you create sidebands above and below the original content. I'm guessing that's what you see in the side channel (this will happen with any limiter with comparable settings).

@@DanWorrall it doesn't happen with all the modes. And just to clarify by side i mean sterio content. Thanks for the reply Dan

@@stelthtenau the amount of sideband content added will depend how fast and aggressive the compression or limiting, so I would expect to see different results from different algorithms. Unless the differences are huge I still think it's just extra sideband content.

@@DanWorrall i found some algorithms didn't create any extra side information. Any thoughts on removing it after limiting?

@@stelthtenau they all add extra harmonic content, that's just what happens when you modulate the gain. The only question is how far up and down those sidebands extend, which will depend on the speed of the limiting and how hard you hit it. It could be that the fast snappy behaviour that makes you like the sound of the modern algorithm is precisely the reason you see more of that extra content. You can't really remove it after limiting without risking breaking the limiting. I guess a linear phase side channel HPF might be ok, but I wouldn't recommend it. If it's a slight increase that you're just seeing on an analyser: sidebands, don't worry about it. If it's a major increase and/or you're hearing it, then something else is wrong (no idea what).
