Amazing Content! I've just started my journey in sound design and you're content is one of the best ones!
Thanks for the description. Immersive audio is definitely the future as Apple and Amazon release more and more hi resolution audio with 3D codecs. Our family is addicted to immersive sound listening for ANY source ( cd, SACD, gaming, movies, streaming) with Auro 3D selected. It’s up mixing is just that good compared to other formats such as Atmos or DTS:X. Just turn off your floor speaker amps and listen to the height channels only. You’ll be amazed by Auro 3D. Enjoy.
Thank you man.
very good ! thankyou
Thanks mate, great information.
I love to see an ambiatic sound editing for dummies video. I love recording the sounds in the field with my VR set up, but I don’t really wanna fuss about with anything that sounds before I put them onto UA-cam
Honestly thank you! I'm trying to figure out why my surround sound speakers aren't always "on" like they used to be but I connected via optical and in guessing this is why
THANKS amazing explanation - I have a quick question - I made some enhancements to my dialogue stem - How can I create the new "LRCLfeLsRs"? Can I do that using Final Cut Pro X?
GREAT CONTENT!
Thanks!
@@AlteraSound You deserve more views buddy. Keep going!
that next episode would be great, lol
I've been splitting the subsequent episodes into more specific topics about different types of immersive audio. You can check them out in this playlist - ua-cam.com/play/PLiZAg-V_54OHHzdjXvC53FJSDrAx_ssoU.html
@@AlteraSound thank you
I wanna write songs classic hard rock and record with intent surround!!!! But I got no clue
Ambisonics?
Can you make a vid about Steel Series engine for Rainbow Six Siege or gaming basicly? I have arctis 5 and the engine I HAVE NO IDEA ABOUT THE SETTINGS :(
@1:19
"...we can make sound appear to be coming from anywhere within that 60° arc"
If you listen to high-end gear, that is matched (the gear gels), in a sound treated room, with professional 2-speaker placement (stereo), then you will get a 3D soundstage, unlike anything you can get with surround-sound.
The presentation will appear to be coming from behind the speakers, in front of the speakers, between the speakers, and beyond the outer edges of the speakers (and by several feet).
This is somewhat difficult to achieve, and requires more than the right equipment. It also requires the right source material. Most music is not recorded with high fidelity, and the better the stereo, the worse most music will sound (because the studios are too often incompetent).
Only a small percentage of music lovers will ever experience a spectacular musical reproduction, due to all of the room requirements and equipment requirements (it gets expensive quickly).
I have had the good fortune to hear such a stereo, at a high-end store. Any one component cost more than most folks would spend on their entire stereo.
You do not have to spend a suitcase of cash to get 80% - 90% of the way there (it gets very expensive when you try to make a great sounding stereo just a little greater -- diminishing returns -- and $$ do not always = better results). It will never be inexpensive. But with quality speakers from Wilson, Ravel, Klipsh, Magico, Vandersteen, etc, professionally set-up in a treated room, your eyes and ears will be fighting over whether or not the band is really in the room.
Approximately 50% of the problem is room dimensions and room reflections. You can spend $500,000 on a stereo, and it will not sound good in a bad room (and most rooms are not good).
Many people think that they have heard amazing sounding stereos. I thought so, too, until I heard the real deal at the high end stereo store.
Here is an example of the type of stereo you would need to reap the most out of a 2-speaker set-up. It is not the one I heard. But it is just an example:

The main difference between surround sound and stereo sound is the accuracy of the musical presentation.
Yes, surround sound can make sounds come from any and every direction. But it will sound contrived. It is often very entertaining. But it will not accurately reproduce the sound that was in the room when it was recorded.
Stereo speakers will not make sound come from behind you. But with the right set-up, the sound will be scary real, and make you swear that there are other speakers in the room. But it has to be in the recording, and sadly most recordings fall short.
An example of a song with a very wide soundstage that extends far beyond the outer edges of stereo speakers is Madonna's Vogue, from this album:
us.7digital.com/artist/madonna/release/celebration-single-disc-version-589241
Sound quality varies, from album to album, for the exact same songs. The record companies are very inconsistent, and mostly get it wrong.
If you do not hear what I described with the above example (Vogue), then either your speakers are not good, are not placed properly, not good digital transport or DAC, not good amps or pre-amp, junky interconnects, room reflections, etc. Get most of the above right, and you will hear that song blow your mind.
My point is that the 60° arc statement @1:19 is simply not right. Yes, that is from where the sound is being created. But your ears will convince you differently. I very much enjoy the host's videos and learn from him. But in this instance, he is in error. Stereo speakers can make the sound appear to be nearly a 180° arc, as well as depth both behind and in front of the speakers.
Cheers!
Our perception of where sound comes from is just that, a perception. It is heavily based on our expectations and interpretation of what we're hearing. From a technical perspective, sound in a stereo system only comes from somewhere between the two speakers. By playing with psychoacoustics and human perception of sound, a mix engineer can make a more spacious mix that appears to be larger than a stereo system. I talk about that in my video on Periphonic Sound. The effect is more noticeable on high-end systems and rooms with proper acoustic treatment, especially LEDE designs.
The problem is that such effects are inconsistent and somewhat unreliable, because again they rely on each individual's perception of the sound. Surround setups are much more consistent at reproducing those qualities. When it comes to music, stereo is generally the better approach just because it's so much harder to find content produced in surround. There are some excellent surround albums though, like Seal's surround releases. There are also a lot of superb classical albums released in surround. The effectiveness of the surround image depends on the genre and production of the music.
For film content though, surround is much better because it provides a more consistent and reliable experience.

Movies:
They create movies with audio tracks geared for surround sound systems. I assume that it makes for an exhilarating experience. I have no room for such a set-up.
If there are music files that are recorded for surround sound, then maybe they sound good, too?
But most music is between "poorly" produced to "pretty good" produced. And since they rarely get stereo recordings done right, I have no reason to believe that they get surround sounds music to sound good. The band / artists have amazing talent. It is the engineers that put it to vinyl and convert it to digital that screw up the sound quality.
For sound quality, I am not referring to the effect of hearing someone playing an instrument to your right. I am talking about hearing someone playing an instrument to your right, and really believing that they are there, as if you can reach over and touch them. That is where a great music recording played on a great stereo shines.
When you have the right combination of stereo hardware and a gem of a recording in a treated room, then anyone that listens will be blown away. It is not something that people will look at each other and argue over the realism. Rather, they look at each other with disbelief. Everyone that listens (seated in the sweet spot) will have religious experience (so to speak), because it sounds spooky real.
I had to get up out of my seat and walk towards areas of the room where it sounded like the sound was coming from, just to make sure that the store was not fooling me with additional speakers. As I moved away from the ideal listening position, the magic dissipated, and I could hear the speakers firing forward. And I could hear no other speakers in the room. The two reference speakers that they were playing threw a huge soundstage that extended beyond the speakers in every direction (except downwards).
From the seated listening position, if I closed my eyes, my ears could not identify the location of the speakers. On a great stereo, the speakers disappear. You hear only a wall of sound, and one with space between each instrument and each singer.
What I am talking about is very hard to set up, even if you have a huge budget.
The store that I heard the above in is named Audio Connection, in Verona, NJ.
By the way, I used Madonna's Vogue song as an example, because it is very hard to find pop, rock, heavy metal, etc songs that sound that good (I am not talking about whether you like the song -- I am talking about the realism of the song). It is my understanding that classical and jazz songs have a better shot at great sound quality. I would love to hear some examples. But I know nothing about those genres, and would not know where to start.
I do not know what "LEDE" is.
@@NoEgg4u Whether or not you like the music is separate from how achievable it is to create a surround sound experience. What you had described to achieve a surround effect with two speakers puts it out of reach for people who live in apartments, people who don’t have an entire room to transform for just listening, people who don’t want to be locked to one sitting position, and anyone who doesn’t have a ton of money to blow on this hobby. 5.1, 7.1.2, and binaural w/ head tracking are a lot cheaper and don’t have any of those other problems. It makes way more sense to pursue spatialization through these means.
