5.1 Surround in Blender - Stereo to 5.1 in Audacity

November 26, 2018
Hey all!

This is a bit of an oddball tutorial as it contains two tutorials in one. Blender does an amazing job of surround sound, but in addition I get to share with you guys another solution that just really helps you deal with the problem of working with stereo when you really want surround - conversion!

So without ado, here is the tutorial itself:


GOD is so awesome!! (^^,)

 - So how good is Blender at 5.1?
Well, surprisingly, really really good! The only downside, as mentioned in the tutorial a few times, is that Blender does not render or generate or give you the option to control any form of the LFE. You can make a generated center/bass from the three front channels' full range.

 - Why a conversion and not the real thing?
Another great point and as bad as it may seem to say, I really like the conversion result. If I am happy with it and the LORD is satisfied with it, I am certainly not going to fight HIM on it. I have enough on my plate as it is, hahaha.

Besides, for Exodus, I would like to add a mix as well, containing additional SFX for the back speakers. Can't promise this, but it is something that is rolling around.

 - There is no 5.1 on the video!
No, and that is because YouTube doesn't support 5.1 playback on most devices. Some people claim to be getting true 5.1 (personally I think it is simply them having speaker fill on). I can't argue per-say, since I haven't been able to test it on so many devices (just not enough data or devices). What I did do was to upload a short file and see what happens with that and while high quality, it did not switch to 5.1...

In the product forums people have talked about the issue. They say that YouTube does receive 5.1 and takes all the channels into account when creating a stereo downmix for output. The only problem is that the recommended upload settings suggest that YouTube supports 5.1 playback as well, not just encoding.

Spatial audio is different since it is headphone based. You get a stereo signal output, not 5.1. It only takes your position into account for the appropriate sounds, but the signal you get is still stereo.

Some suggest that the reason YouTube doesn't support it yet, is because HTML 5 doesn't support it. Which isn't true. There are websites where you can test it and it works (when you test it make sure speaker fill and bass management is turned off). So saying that the browser or HTML 5 doesn't support it doesn't hold water.

I think it may come down to data usage. 5.1 means that you are getting audio that is 3x larger than before - even if you limit 5.1 to 480p and up, its still a huge ask and there is currently very little audio playback options for YouTube.
In the meantime, you're simply going to have to take what I say with a grain of salt, stick with stereo on YouTube and simply try what I showed.

 - Is it worth using Blender for 5.1 as-is?
Not as a solo tool for surround sound. Because of the LFE issue, I have added a proposal to right-click select so that it can be generated, so you can go give that an upvote! It'll really help a lot!
https://blender.community/c/rightclickselect/qlcbbc/lfe-in-the-vse

 - So, conversion?
I luv this set of plug-ins. They are VST and technically designed to work with software that enables you to connect plugin's in a way similar to nodes in Blender. They use harmonics and various things to help build a surround ambiance for your audio (much more and much better than reverb). It is truly a blessing!

There are different plugins for each set of channels, so you don't need to have a digital audio workstation that can work with 5.1. If you do, please use that, because you would have an advantage doing it that way.

 - Where did the idea come from to seek conversion?
Well, this is something of a mixed bag. The primary reason for seeking conversion is a sound system we had. I shared this before, but you're hearing it again today, hahaha. A few years ago, we had an LG surround sound system with Dolby Surround built-in. It was the coolest piece of audio equipment we ever had as far as I was concerned.

It only had a stereo input, but could take that stereo input and make it 5.1 and it worked. I was stunned - and promptly devastated when lightning struck it... The replacement couldn't live up, seriously!

Since then I knew that you can get 5.1 from stereo and it sound truly epic! The LORD kept that in the front of my mind and when this came up, it was the logical choice.

Beyond that, it was also the practical choice. Blender *cough* *cough* LFE *cough*... haha.

This was truly a fun tutorial to do and I know it's been a huge blessing to you too! I enjoyed making it, learning through it, struggling through youtube's 5.1 issues and so on. It was an adventure through sound, hehe!

I know you learned a lot from it!!

Biggest thanx to GOD for helping me with this. Without HIM, none of this would be possible! :D

Know JESUS yet? GOD is reaching out to you through these videos. HE loves you more than you can imagine and wants you to know HIM. Not because HE's lonely, but because HE loves you and paid a heavy price to enable you to go to Heaven, where HE is. See, we all have sinned in some way shape or form. That makes us guilty before GOD. If you have ever said that you hated someone, in GOD's standard, you have committed murder (James 4). If you've ever looked on a person with lustful thinking, you've already committed fornication with them in your heart and you are then guilty of sexual impurity. If you were to face GOD on judgement day, saying: "I was a good person" will be a void argument, just like it would be before a human judge. GOD knew that we would have to pay that penalty and that we could not pay it, even if we tried, but sent JESUS to pay the price for us. Your sins were put on HIM and the forgiveness that is there for you was by no means cheap - the cross was not padded and comfortable, neither was the death.

But, HE was raised up on the third day (after being crucified) and finished the work so that we may enter through HIM paying the penalty we were supposed to pay, but it is only valid for you, if you accept it and live for HIM.
If that is you today, please, follow this prayer:
"JESUS, I believe that YOU are real and I believe YOU died for me and was raised on the third day for me. Please forgive me for my many sins. I make YOU the LORD of my life, full time and to fill me with YOUR HOLY SPIRIT. Teach me how to live for YOU, help me become what YOU have made me to be, in JESUS' Name! Amen!"

Have a great one!!!

Optimizing Node Groups

October 31, 2018
Hey all!

NOTE: Don't just skim the headings - they are not clear enough for you to know what I mean.

I got to share with you all a special set of group nodes affectionately called 2Depth. These cover 2D to 3D conversion and some other depth based nodes. One in particular is called the parallax 3D node and this one was known mostly for it's slowness and secondly for it's sharp 3D results. Now, it's going to be the other way around!

The LORD helped me take the processing time down to 5 seconds fro...

Tutorial for the node groups

October 27, 2018
Hey all!

Recently I got to share some seriously awesome node groups with you guys and today I get to share a tutorial about how some of them work (based on how a few works, you'll get how I was led to build them and be able to use them easily).


GOD is so amazing!! (^^,)

Because I know a lot of you are new to nodes, I would like to make a short FAQ here about what they are and why they are what they are. There was a time in my life when I opened the node editor and promptly closed it, hahaha, so ...

For Anime - Garden Sprinkler

July 17, 2018
Hey all!!

About a month ago, I uploaded the last tutorial which was also about a specific kind of sprinkler. This one, quite different in approach, is one of my absolute favorites (see the applied example in the tutorial).


GOD is so awesome!! (^^,)

Again, there was no reference for this online, since sprinklers are either a background element in anime or completely ignored as far as art is concerned. So, finding reference didn't happen. I looked, again, at how water is handled and how I've handl...

For anime - Course sprinkler

June 19, 2018
Hey everyone!

Yes! It's tutorial time again and this time we get to cover something that is rarely seen in anime (at least from what I've watched)! Sprinklers! Not just any, but those gholf course type from the 80's and 90's mixed with what we have today. I am so grateful for the result!

Without further ado, check this out:

GOD is so great!

 - Sound
   I had major sound quality issues over the past year or so. It has been a nightmare to get clean audio! I was frustrated to the max! Everytime though, GOD did come through and I got okay audio, but there has always been a significant amount of noise - at least to the point where I couldn't remove most of i...

2D to 3D conversion - Proposal

April 9, 2018
Hey all!

I had the amazing priviledge of being able to write another proposal on Right-Click Select! Shockingly, I didn't actually blog about it, so that is what this is! Yay, hahaha!

So the basic idea is that you use the existing depth information (mist pass) to slice up the scene in as many slices as possible, causing something like this:



This means that you can now shift these slices and create what your eyes will see. I was extremely opposed to it, but it actually does make more sense to do ...

Epilogue

January 3, 2018
Hey all!

Don't you just love that title?! Sounds so epic! It was from a concentration standpoint. Goodness! hahaha.

With all the work said and done, we have:

Normal and Bump Mapping


Works with averaging what is there with the map itself. Gives a nicely balanced result. Bump maps are also converted to normal maps, but purely based on a flattened version that is connected to all three axes.

Ambient Light


For this feature, I simply added an emission shader and fed it, based on circumstances, either th...
