Even though I knew already a bunch of fundamental stuff about sound but I have no option to leave any video of this channel without watching. Audio University explains so deep and yet very pleasing. There is always to learn a new thing, in a different approach
Thanks! Although I do know most of the stuff your talking about I haven't seen a channel so well put together explaining everything in an easy way for everyday people to understand.
I’m glad to hear the videos are helpful! Thank you! I really appreciate that! Please share with others who are learning audio production! Also, let me know if you would like to see any subjects covered in future videos.
Great videos as always, I'm taking notes like a madman. Should have done this YEARS ago, but better late than never! I am thrown on that last one, how adding 6dB doubles the SPL and subtracting 6dB cuts the SPL in half. I would love to hear this expanded on, maybe I will as I keep making my way through your unbelievably valuable videos. Thank you so much for this free education .
That's not quite correct either. Adding/subtracting 3 dB doubles/halves the power, but adding/subtracting 6 dB doubles/halves the SPL (sound pressure level), like the video says. And adding/subtracting 10 dB doubles/halves the apparent loudness (how humans actually hear things).
Thanks for the videos. You have a way of putting all the cookies on the lower shelf so us kids can get at them. That's talent. Much appreciated. I'm now a subscriber.
I am loving this series, recently ive been thinking about getting more serious about music and understanding audio quality in general and I can already see this will be a great starting point as I love this systemic and organized way of learning. Thank you very much.
this is a nice review of what i've learned in school, but do you have a video on why waveforms on practical recordings look more complicated and nonuniform compared to this?
The waveforms shown in this video are simple signals, containing only one frequency. In practice, you’ll see complex signals, containing many frequencies. You can learn more here: ua-cam.com/video/GLnrysQ1Erg/v-deo.html
@@AudioUniversity I'm learning a bit, but the graphs confuse me a little. The graphs of the tone generator in that video aren't pressure over time but levels over frequency. I'm curious as to what the graphs of the tone generator would look like when shown as waveforms like in this video.
Dear sir, your demo is great! Congrats!!! I have a bad mind on Guitar, DI box and 1/4 inch TRS. Generally we need to fix a DI box when we plug guitar to mixer or other way is via guitar amplifier. But TRS jacks are balanced cable and mixer input is also balance input. Although I have seen many people use DI box and mono TS cables. Why?? We can't use TRS balance cable to fix directly to mixer???? Thanks
A DI box is primarily used to match impedance between the guitar and the mixer. Guitars have high impedance (Hi-Z) outputs. Mixers usually have low impedance (Lo-Z) inputs. Using a DI box will match the impedance so that the system works properly. Also, the guitar output jack is a TS. Using a TRS could cause the signal to be cancelled out by the differential input of the mixer.
Also from the pascal vs decibel comparison, it clearly shows that adding 20 dB means the intensity is 10x. It's base-10 logarithmic. So it's confusing that you said adding 6 dB is doubling the intensity without calling out it's an appromixation.
I don't understand how you can change period without changing the frequency? I'm not sure you explained it right. If frequency is measured in CPS - then if we adjust the second -- than frequency would also be adjusted in proportion. At least the way you explained it here. Would love some help here thanks
Hello Buddy, What happens to Your last Video ?. Why you make that *Private* ?. & i asked a Question in that video please Reply for that Question please 🙏.
I had to make a revision. It will be back up soon. Here is the answer to your question: The length of the cable is not the problem. Sound fidelity is reduced in LONGER cables and is better with shorter cables. The problem you’re experiencing is most likely one of the following: 1. A poor connection between wires (most headphones use very small wires that are difficult to work with manually). 2. There is something wrong with the speaker drivers or diaphragms. What is the quality of the sound? (Distorted, muffles, etc)?
Thanks for the Super Quick Reply .🙏 & About the sound Quality is Like it lost High Tones (terrible) & Really Bad Quality Base, that Hurts My Ears . Can it be Due to Wrong Polarity of My Soldering ?
Polarity wouldn’t cause this problem. You can learn about that in this video: POSITIVE VS NEGATIVE: Does Speaker Wiring Matter? ua-cam.com/video/EeKT4yD3UX4/v-deo.html How many wires were in the cable?
3 Wires are in The Cable . Red Green & Yellow. & Connections are really strong (Soldered by me carefully). I think Red & Green are L & R & yellow is Common .🤔
There is something that i don't understand about the part of the lenght of a wave: given the sown equation (wavelenght = speed of sound/frequency), you can figure out how actually large 1 cycle of the wave of a certain frequency actually is: so if i want to know how large is a wave of let's say, 440hz, you do 343 m/s divided by 440hz, so 343/440 = 0.75. (i googled it and its true, the wavelenght is in fact 0.75 mts wide). So what i don't understand is: if a sinewave playing a frequency of 440hz through an amp speaker has a wavelenght of 0.75 mts (that is, if i didn't misunderstand, when the wave completes a cycle, the wave would've travelled 0.75 mts), *how is it that i can hear it using headphones??* I shouldn't be supposed to, because there is literally less that 4 cm between the speaker of my left headphone and the timpani in my ear, so the wave has no time to form in order for my ear to identify it as that certain frequency. Of course, what happens is that i do hear it normally, so evidently there's something i'm not understanting (and it drives me nuts not understanding something). What is it?
Careful now. The phase numbers you show in the beginning is the phase of the so-called complex Phasor. Looking at the real sin signal alone you would say that the phase is zero with an amplitude of one.

Very Informative. The good thing is you are explaining the physics behind sound. This is valuable. Thank you very much.
Hi, Just wanted to let you know that you're doing a fantastic work ❤️
Adding/subtracting 3 dB is doubling/halving. 6 dB is quadrupling/quartering. Aside from that minute detail, VERY well done! Thank you!
That's not quite correct either. Adding/subtracting 3 dB doubles/halves the power, but adding/subtracting 6 dB doubles/halves the SPL (sound pressure level), like the video says. And adding/subtracting 10 dB doubles/halves the apparent loudness (how humans actually hear things).

I’m glad this series is helping you to learn more about audio, Lucas! Are there any topics you’d like me to cover in other videos?
Thank you for making these videos! Super clear, super helful :)
Thanks for watching, Haley. Glad to help!
thank you!
Excellent, this is really we explained
Glad it was helpful! Thanks for watching!
Very useful thank u
I wonder why the youtube algorithm thinks I prefer to watch random videos from 2010 instead of this.
Thanks!, great video.

Thanks for sharing, Rene Christensen! Much appreciated!
I like the content but using British Metrics in a scientific formula like wavelength = sound speed / frequency is annoying.
