My man! I'm an audio engineering student at KCKCC and I just want to thank you for all the time and effort you put into each one of these videos. They help out so much!
I’m glad to read this, Brayden! Thanks.
Are you trying to be a recording engineer or what?
@@luciferianjesuslover9453 yes sir. I’d like to get into live sound but just trying to get my foot into the door atm.
@@braydenblankenship1432 I’m trying to do the same, it seems very difficult to do without starting as a stagehand for a couple years. Let me know if you do get your foot in the door, good luck!
Man, your videos are PURE GOLD, there's a lot of misinformation in UA-cam, rookies that upload the wrong things they think they know, but your channel is here to save us all, thank you so so much, greetings and blessings from Peru
Thank you! When I forget the difference due to a lack of practicing, I try to remember visually, that polarity it's a Vertical thing (just up-down), and phase is an Horizontal thing (just left-right) where Time is added to the equation. Or polarity it's just a matter of voltage, and phase it's a matter of time. Those tips help me to keep it fresh but I think the more you work with your DAW, the less you have to recall the tips!
Thanks for these tips, Veronica!
So well explained, you've made a great educational work with your channel. Thanks!!!
Jam Packed info in about 3minutes. Love this man
I’ll admit - I thought they were interchangeable for a long time. Once you understand the difference, you realize why it’s so important to differentiate. Thanks for watching and commenting, @rishey rsp!
Incredible explanation without going crazy! Loved it! Thanks so much!
Thanks for watching and commenting, @Daire Barefoot and the Siren! I’m glad to hear it was helpful without being overwhelming! Please share and subscribe!
Getting the Basics right from all your videos.Thank you so much❤️
Glad to hear that, Gokul! Thanks!
This is teaching at its top skill level.
Thanks Grand Rapids57. I’ve felt very inspired reading your comments! I really appreciate your support.
This is great and you explained it so clearly. Thank you!
Glad it was helpful! Thanks for watching, RongeForever!
That was an extremely good video. Great stuff. :)
Crystal clear explanation. Thank you!
What?! In under 4 minutes you saved me hours of stress! Ty for the examples and boiling the details down.
Perfect description
Very very well explained!
great videos, Thank God I had the chance to came across these channel, I'm majoring in Piano performance but my main goal is to be a music producer, and it's important to get the basics of Audio. Wheter I go to a college for Music production or not, at least I'm learning the basics of Audio thanks to these channel. Greetings from Peru
Glad to help, Ronald! Thanks!
Thanks!
Great video
So well explained!
Thanks again, @Ninja Duck!
I’ve been watching all your videos. They are very to the point ! Can you do a video on delayin tops Speakers in relation to subwoofer delay distancing and sound implications
Thanks! That's a good suggestion! I'll try to make a video on that in the future!
Thank you very much......perfect explanation in few words 👍
I’m glad you found it helpful! Thank you for watching!
Thanks you,greeeeeeeaaaat 🙏🏽
Thank you :)
Thx for this great introduction! Just subscribed and rung the bell :-)
Welcome aboard! Thanks, Morten!
Hi, I like your video. Thanks
Thanks Sir
Best channel!!!
Wow! Thanks, Rony!
Great explanation! 😂
Incredible
Thanks, Dustin!
Thx so much. I just clicked on the link and will look at the guide on my email address
I have some pics of where the speakers in the church I play at are located and need a way to send them to you along with where the mixer is at
Dude, nice
Thanks, Victor!
Any solution to my sound card lacking a button for inverted phase/reverse polarity? I have found that in my daw it really helps to hit the button in the mixer, but I'd like to have a global solution and a hardware one would be great. I use my speakers and my microphone causing some issues, noise-cancelling software is taxing on the cpu and likely very unnecessarily.
Great video! It really helped me! I just have one question:
Can I invert tha phase of my output cable of my pedalboard and conect it directly to the input of one of my amplifiers? I won't fry anything by doing that?
It won’t be as simple as flipping the wires in the cable, because it’s an unbalanced connection.
great work sir.
you are a genius.
I admire your brain.
thanks.
your student SHAHEBAZ from india.
Thanks for watching, Shahebaz! I'm glad you're finding these videos helpful!
The shift at the end of the three frequency components was a time shift, not a phase shift. A time delay corresponds to a linear phase response where each frequency is shifted different in its phase. So to keep it short; polarity is the special case of a 180 degree phase shift for all frequencies which is not the same as a time delay.
Thanks for clarifying that, Rene Christensen. Much appreciated!
I have "seen" wave form that obviously does not have positive half mirroring negative half, in that case, adding a opposite polarity signal of itself will continue to cancel out (destructive interference) each other, but adding 180 phase shift of itself will not do the same "complete cancellation"
@@philiptong4978 They make the same mistake of obtaining the 180 degree shift by shifting the signal in time. That is not what a system with a transfer function that shifts the phase would do.
Good
Brilliant!
Thanks, D Young! I'm glad to help!
@@AudioUniversity Do you have a video on audio resulution. 'Whats the difference between 16 and 24 bit' that sort of thing?
I plan to make a video on this in the future. Until then, maybe this video will help you - ua-cam.com/video/844LQegRV-A/v-deo.html
Excellent video!
Is there a name for the line at which the sound wave is located at 0°, 180° and 360° throughout a cycle?
Thanks, Parker! The line represents either amplitude or displacement.
I have speakers in 2 rooms running off of the same amp. Some of the wires are in the walls & there are no marking on the wires & the wires are both the same color. To compound the problem, one room has sealed bookshelf speakers so I can't see the direction that the speakers are moving. Is there any way I can determine the polarity of the book shelf speakers since I can't see their movement?
While it would be ideal to wire both speakers in a way that a positive voltage creates an outward movement, the most important thing is that they are in the same polarity. You should be able to listen to the speakers and tell if they are wired differently. Choose the wiring that sounds best.
connect a battery and voltmeter at each end to check the wire pair?
for the speaker pair, relocate them to face each other as close as possible, play identical content on both unit at the same time, if one of them is wired incorrectly then destructive interference will happen and result in much lower volume compared to both wired the same polarity (compare result with same speaker location, orientation and listener location, orientation)
❤️
preferably 0° or 180°?
Another (nameless) UA-camr made the statement that phase alignment and time alignment were two different things. He did not clarify or explain. Do you have any idea what he might be talking about?
Phase alignment has to do with time, but it’s often frequency-dependent.
For example, speakers often experience phase shift, where the phase of some frequencies is shifted in relation to other frequencies. So, a simple time alignment won’t necessarily optimize the alignment between a subwoofer and main speaker. Instead, it’s best to align the phase at the crossover frequency.

If someone else tries to explain this they probably would have lost the student.
Very helpful video sir. Thank you
I have one active sub(polk audio)
Witch is the safe driver work Phase 0° or 180°
Phase = opportunity of 360 degrees, Polarity = 180 degrees swtich. Often misnomer, misused, abused term. Also known, or at least implemented as " Mid / Side " micing and mixing techniques. But the balance of which is where the fundamental sense of 'depth' in *both* Mono and Stereo lies. It is into the *Z* axis.
So polarity is when you are going against the zeitgeist, but phase is when you are simply ahead of your time?
