I struggled for decades with these types of problems and compounded them with some of the quad shows we did . Taking the immersive sound live years ago was a challenge . Some of these shows worked out great , others not so much . Now retired I sit in my barn listening to Atmos 5.1.4 and again all mixes are not created equal . Thank you for all your work and information .

Audio engineering is a complex science that involves a lot of mathematics and logical problem solving. In real-world situations, it calls for compromise and best-case scenarios. This video presentation does a good job of introducing some of the challenges that audio engineers are faced with in sound system design. Great job!

Audio-engineering, i.e. developing and designing audio-equipment, involves a lot of math like every other field of engineering. A sound-engineer is not really an engineer and very little math, if any, is required. This is very basic stuff.

I love Lacoustics, always the best system to mix on, but it certainly is convenient that a speaker manufacturers answer to improving coverage over a typical L/R system is..... wait for it: Too buy a lot more speakers, 18 Kara configured L/R to cover a venue becomes 45 over 5 hangs. Also what is less clear is how you would maintain the L -isa coverage with a front fill.

I just barely commented on an AVIXA video how I would love to see a Dolby surround schematic unique to each venue showing where each speaker is attacking and whether correlated or not. And with that I would love to see brakes put on AI with some kind of mandatory human input for the result.

@Speeder84XL 4 ай бұрын

Really interesting! Quite incredible how clear if becomes with the comb filtering problem when using the pink noise (seems like the room was also quite good, and not introducing disturbing reflections) - there are even some minor changes in sound as you walk around (reflections against your bodies - even though, that was still very small compare to the speaker issue it self). But, that typical behaviour as you walked past the middle with the microphones is really caracteristic on music as well and I have heard it so many times on different live performances, trying to find the best sound in the middle. This is also an issue when making good live recordings in stereo (which I have done) The optimum line in the middle is so narrow, that just the smallest movements with the microphones will cause the sound to get skewed (even movements so small they are barely noticable on the video - if filming along with the sound recording). The worst case is when accidently moving back and forth over the optimum line, so the sound "wobble" from side to side. With an audience around that moves and a some music that makes you want to move along with it, it's hard to keep the microphones steady in the middle, haha. That software seem really smart.

Ok, so you can compound tricks and mostly solve the high-end. But what about the bottom end? e.g. for 30Hz one cycle is 33ms, to decorrelate it you have to move one signal by significant amount, and since the frequency is so low the comb also each affects more neighboring frequencies as well. For smaller setups e.g. a home, one sub speaker is an amazing solution, but I've no idea how you'd fix it in a multi-speaker setup Nice demo btw!

@toddwilliams8761 3 ай бұрын

Human hearing (the way we perceive sound) is such that low frequencies lose their directional component. Conversely, the higher the frequency, the more we are able to discern the direction that the sound originated from. It's the same reason that we feel boomy bass frequencies in our chests (it sounds like it's everywhere), and high frequency cymbal crashes come from the right or left. It's no mistake that modern stereo systems have one sub-woofer (with both channels) and a right and left speaker. That type of arrangement (theoretically) maximizes the stereo effect that we hear. Audio engineering is a complex science that involves a lot of mathematics and in real-world situations, calls for compromise and best-case scenarios. This video presentation does a good job of introducing some of the challenges that audio engineers are faced with in sound system design.

@@toddwilliams8761 Was this written with ChatGPT? Comb-filtering in low-frequencies results in power-alleys which have nothing to do with the "directional component", i.e. our ability to locate a sound source.

@roadiesnrockstars 4 ай бұрын

The basic problem here is the premise, yes there will be comb filtering as you move through the venue, but that’s not what the audience is doing. The audience is sitting in a seat. A fixed position. What really matters is that every seat has direct audio. Iv done shows with thousands of speakers 🔊 under every seat in the venue. If you walk around you would hear comb filtering but sitting in your seat, the direct audio delivers clarity without energizing every molecule in the room. 😉

You want every seat to sound to sound the same and have an even frequency response, not have one where you have huge dips or worse, resonances.

Since we can determine the angle of coverage of each array of speakers, why can't we just hang them at the center of the stage and hang other arrays next to each other in a curve configuration depending on the speaker's effective coverage to create a balance sound field, eliminating the phase issues. Would that make sense?😆😂. I am no expert, I don't even know what I'm talking about😂. Very informative video anyways.

@@jean-lucbattista2492 I guess most sound systems are using mono sound regardless if they have a left and right set up, coz we all know the problem of sending stereo to a wide area. I think you can only use stereo output if you can ensure that your audience is in the same position in both the left are right of your speaker array. So my point here is even those setups with left and right arrays are outputing mono sound

@@LostSoulsMed. perfect you've positioned your first sound object. now create a second one in a different position. And what if you want 64 sound objects? Do you create 64 mono stacks with perfect coverage? Or do you want the help of L-ISA to calculate a sound field from fewer sound sources , that will well represent that sound object position? Thats the goal !

@@iliketoast-q9b each sound object is a different signal. You don't need a decoding matrix to send the same signal to all your speakers... Definitely not a good idea. I made a mistake in the last sentence. You want the help of L-ISA to calculate a sound field from fewer sound sources, that will represent EACH sound object position... Up to 64 sound fields.
