I can hear this on my BT headphones... I didn't think it sounded bad.

So, what about micing up a snare drum with two identical mics, one on top pointing downwards and one underneath pointing upwards? Or standing at a mic between a pair of speakers (mono) that are directly facing each other?

*Fast forward to **6:43** if you don't want to hear all of the RAMBLING BLA BLA BLA*

I suppose we shouldn't tell these guys that a difference in distance from ears to speakers of only 1/4 inch could place the entire top two octaves of the audio bandwidth out of phase.

It is just as important as the jitter BS. Not at all.

Line arrays will produce phase effects as frequencies go in and out of phase. They are the audio equivalent of diffraction gratings in optics.

Well that just great....so now i need to figure out ...on the ear buds i listening on ...if there is a setting in the app for ear separation and tone sensitivity of different Frequencies In each ear....this might take some time...by the way thank you for adding to my confusion Phil

96 FLAC is your limit and its does sound good from HD tracks i have Tori Amos albums are so clean With it in my opinion

I’m listening on headphones and the distance between them just increased thanks to this video.

Dedicated listeners will want to consider a surgical 're-balancing' of their ear canals so that these variances can be removed from their appreciation of audio coherence.

The distance between your ears certainly has an effect at high frequencies just by turning your head sideways.

Worrying about "phase issues" is on the same level as needing expensive RCA cables and speaker cables... (But if they care so much about sound quality, why are they using RCA cables?)

I identify as phase neutral

i heard some static sound

wtf did you just say

In order to solve all phase issues you need to employ semi-critical quasi inverse didactic convolution. To determine the amount of convolution required you need to calculate the complex impedance of a non-resonant dipole located in 70% curved space and 3.2 parsecs away from a third order catastrophe cusp. Then use the conjugate of the complex impedance and multiply it by the reciprocal of the impedance of free space. Best results from this process are obtained by carrying it out ten seconds in the future and then correlating it back to the present. This can be achieved by using non-linear inverse time regression techniques which will also cancel any time dilation distortions.

Really the only time I've noticed any phase issue is between subwoofer(s) and main speakers, and then the phase issue might be propoerly passed on to the neighbors.

What, me worry about phase shift??? Not really... Are my speakers time aligned? No, they were built in 1954! How about the subwoofer? Ours is an older one without any adjustment for phase. At least it has a decent crossover, or so I think. In our modest townhouse the sound is fine at least with good recordings. The main speakers are JBL C38's with 075 tweeters and D131 woofers. They have been in the family since new and still play perfectly (oops, probably should not have keyed this). Phil said it best! Paul H. Huntington Beach, CA USA

Think Phils needs a haircut, he might be able to hear better then.

+6dB? adding 2 equal sound sources?...... LOL....

Phase is a crucial concept in the theory of harmonic decomposition of signals, such as in Fourier theory. Phase shifts associated with low-pass, high-pass and band-pass filters negatively affect pulse response, which can certainly become audible, smearing attack transients in time. It is also one of the issues affecting PRAT (Pace, Rhythm And Timing) (as in the _audiophile_ use of the terminology, not to be confused with _musicians'_ use of the same terminology but which means something completely different.) Accuphase deemed phase to be such an important factor in audio technology that they based their trademark on it.

Omg 😮😅😊

Yeah, unless a skull is hollow, headphones should not have phase issues. I'm guessing brain tissue would muffle any sound

As i listen to the dust and dirt rake over my old Jon Baldry Lp IT AIN"T EASY, Does a scotch and soda have phase issues? Best Regards Jack.

it seems obvious that if you listen to 2 channel stereo it sounds best if you sit at an equal distance from the speakers and you've cabled them up with equal lengths of cable and they are placed the same distance away from a wall etc. etc. But who has a perfectly symmetrical room and even if we did would SWMBO let us put our speakers where we want? But you don't have to have audiophile ears to hear if you've connected one of your speakers the wrong way around though, it just sounds a bit odd... I guess though that asymmetrical room reflections cause loads of phase issues... and phase issues can be caused by a crossover circuit? It's amazing we hear anything at all 😉

If you have a surround sound setup or quad speaker stereo, the distances can be set (wrong) in the receiver, phase issues unless you have space enough to put them equidistant from each other (though pointing the surround speakers toward each other, phase issues). This can result in a stereo center image that's hard to erm center, or there's an audible hole in the sound stage where no sound is coming from which sounds odd as if one ear is plugged up. Putting speakers close to a wall, lower frequencies bounce on the back wall (behind speaker) and phase issues. High frequency sounds bounce at the front wall (behind you) wall, phase issues. Speaker drivers that are offset in distance from each other, phase issues. It's just better to listen to mono one would think lol, just a center channel speaker is enough. Maybe one day a brain link can induce music directly into your synapses without phase issues ;)

I dont understand any of this sorry. I understand that volume is variable and can be quiet or loud. Audio has bass mid-range and treble. Lastly there is a stereo balance. That's about it I think.

I guess I'm an idiot. I listen to You Tube videos and play video games on a pair of Logitech THX speakers and a subwoofer connected to my PC. This setup is more than adequate for listening to You Tube videos and enjoying music videos. For serious listening, I either use my retro stereo system from the 1980s, or my Sony Walkman (plays MP3, FLAC, and WAV) through a pair of Sennheiser headphones. More often the latter because I live in an apartment, and (being the landlord) I have to set a good example :-p

Well, it had to happen sooner or later. Phil making no attempt whatever to disguise his gibberish! But is it?

If you don't have a problem, create a phase issue.

Thank You for bringing this important issue. The phase issues you are referring to are limited to constant level infinite tones. There is a whole world of "Time Arrival" issues best indicated by an "impulse response" test. i.e .time alignment between the tweeter and the midrange. Same goes for the effect of a "heavy" low pass filter or a signal equalization on the harmonics of the signal vs its fundamental frequency.

The biggest phase issue is knowing when it matters and when it doesn’t. What does that sound like? I guess it sounds like a lot of time wasted obsessing on something that may or may not matter.

Phil has more serious issues...😂😂😂

Add a 0.1uf capacitor across the meter movement at the rear connections... if it clears up you got off easy.

90 Degrees, Quadrature. :- )

I believe Phil nailed it!

I have been trying to explain this to my friends and family for years. I purchased a pair B&o M100s in 1977. Times alined and phase coherent, which I still have. They have long since gone dark, probably because of the electrolytic capacitors. The cabinets are too beautiful to get rid of them. I have since discovered that the fewer the drivers the less coherency problems you have. Mofi source point 10s does really good job of solving that problem. I have a Yamaha YSP 4000 uses phasing to control It’s projection beans. Not a perfect system but as you say, it’s good enough. Love your content.

I believe there was a manufacturer that invented a thing they called Sonic Holography. Basically, what they did was sense where on the soundstage a particular waveform appeared, and then delayed that waveform by a few milliseconds (deliberate phase issue?), and then recombined it all and pushed it out to the speakers. They had to have been doing a Fourier transform in real time to do this. I denno. I just like my music to sound good, with deep bass I can feel, clear highs that I can barely hear, no crosstalk, wide dynamic range, no hiss or pops or crackles or rumble or wow or flutter. Do that, and I'm happy.

Relative electrical phase difference between stereo speaker drivers - swapped +/- on one channel only - is definitely a thing. Bass frequency drops off, treble can sound "odd", to me at least. But anyone who claims that absolute phase is a thing, is delusional.

Yes the world has gone insane. We need Jesus! On a smaller scale it is ridiculous that a noisy, click prone medium would outsell CDs unless you just love the medium and the nostalgia of it.

TL;DR: if mastered correctly 16bit is good enough

this is the equivalent to snake oil salesmen of the 1800s. And birds arn't real too while you guys are reading this... lol. Let's go to sleep and find a better part of the internet tomorrow.

Yes, but what do they sound like? How reasonably-priced are they? Should I consider bi-amping my main KEF Reference loudspeakers with them? Why not use one 10A PSU for each V3 Mono? This way there should be ample headroom... Ramblings from a closet Audiophile... All the best, Rob in Switzerland

In recording, mixing, mastrering an extra 4 bits at each end is very USEFUL. Concentrate on the music and match levels later. 24 bit does not give smaller "graduations" between bits, thereby leading to a some magic "finer-grained" output. A mixdown to 16 Bit is INAUDIBLE in any practical listening environment. Simple Maths : In a VERY quiet room (25DbA), a 96B DR gives peak levels of 25+96Db, or 121dBb SPL. Very few domestic loudsperler sustems can even radiate 121Db SPL - let alone an UNDISTORTED 121Db SPL. My Tri-amped 2.5 Kw per side RMS system comes close, but it is excruciating for more than a few seconds . Sub 100Db listening levels are satisfyingly LOUD (and clean), with 20Db headroom and a lot more fun. The supposed "requirement" for > 96Db DR during playback, is pseudo-technical nonsense. Here's some education for the stair audibilioty believers : kzbin.info/www/bejne/mXWainmLjrGjesU

That reverbs going to move, if not, expand the stereo image a lil. Honetly, I'd do a resonance sweep for sharp spikes in the clarinet, monitor that a bit, thats about it.

This isn't really an "audiophile' issue though. It's a recording and sound engineering issue if it is one at all, and I don't think it is. Also, those Atomos tracks exist. Though they are a bit less random about jumping around than is implied here. They deliberately use positional sound to create an intentional effect to place music around the listener. Sometimes what you're going for with a recording is something you can't get from a live performance. The entire point is to do that. Other times you're trying to get as close to a live performance as possible. It is a preference thing, but it's also art, so sometimes playing around with the medium is the point. Artists have been messing with this since stereo existed, Stix did this with high fi stereo with the "Kilroy Was Here" album back in the 80s for example. Led Zeppelin also messed around with it with stereo drum recording on a few of their albums to create something you couldn't really get from a concert performance. Not every recording is trying to recreate a live performance. As anyone else, I can appreciate the art and understand the intent without liking it. I can dislike something and still say that there isn't something "wrong" with it. I think this is the case here. There isn't anything wrong with the recording, even though I'd prefer a different and more stable mix for it. I don't disagree with you that this is not my preference for a recording of this nature, but I do see the value in doing things you can't otherwise for the sake of art by taking advantage of the unique qualities of the particular medium being used as well.

I heard and noticed it, but didn't think it was a problem, so that threw me off. I was looking for something actually wrong, but am familiar enough with live music that I know how it sounds when you have an "active" musician playing something.

Just a music lover here. I listened through a pair of Logitech G533 wireless gaming headphones. I'm also currently unwell with RSV so my sinuses are blocked up. I heard it but didn't think anything of it. If anything, the movement of the camera on that lovely misty field made me put it down to either my brain being influenced by said movement or it was meant to move slightly, as if the performer was moving. What grabbed my focus was the occasional sound of his breath and slaps of the valves every so often. I might come back and listen with my Sennheiser HD 280 Pros.

For some reason all I hear with vinyl is snap crackle and pops. Even with good records and players with good carts. I just don't really hear the hiss with cassttes. When I do, it sounds normal. Its all good. I like physical media and the gear that plays them.

Cassettes are hobby for me. I like collecting and restoring them. It can be quite challenging with all the little parts. Very rewarding when you pop in a cassette in and it plays and rewinds. That's not always the case. lots of redos but that's part of the fun. Just received my lot of 35 southern rock cassettes from ebay. looking forward to checking them out.
