I've finally found a way how to code my audio codec on youtube so i created few samples and comparisons.

I've been developing this sound system since 1999 when i was 17 years old and it was in final beta state on 2004.

When i was 15 years old i began to think about this whole concept for one day to have sound so realistic that you'll have the feeling that you're right there so i named my system:

 

- Spc Direct X Sound System - Expanded Stage 7.0XII

(7th version of the system - this is the name of whole system with four speakers and one wooofer + setup)

 

- Spc X Drive II XD

(2nd generation of complex audio codec/coding/Encryption technique developed by me that also includes very complex DSP (Digital Signal Processor) processing so that i can extract voice only for example or music only without voices.. etc  - name for audio codec carrying the code for hardware audio decoder that can decode my surround sound)

 

- Spc Crystal Clear Audio Codec PRO

(An audio codec such as mp3 with special quality format changes that now i can upload to youtube)

 

Here are few technologies that i invented and are a part of the system:

 

Spc Δ Phase Coding®:

Phase Coding with different mathematical algorithms ( pi (), root (√;), multiply (*), divide (/) etc. ..

With this technology i can extract a voice or remove a specific voice / instrument / noise.

 

Spc PRF® (Progressive Reverb Falloff):
This technology enables Reverb to falloff progessively so that human ear thinks it's in the very same room as emulated and also with PRF system can calculate

reflections on materials and rooms.

For example if a room is made out of wood the reverb will have exact the same ammount of reflections and bounces as in real room made out of wood.

Emulation is not limited to one specific material (for example wood) but every material that bounces sounds or absorbs sounds makes an room effect (reverb).

Every object is considered as an obstacle that bounces sound back and forth even if it is a cup of coffe or an broom in the room.

 

Spc FSR® (Full Source Routing):

FSR (Full Source Routing) is an technology that routes audio without any quality losses.

FSR also routes audio within whole system with latency that is less or equal than 12 μs (micro seconds).
 

Spc HASP® (High Audio Audio Sharpness and Precision)

HASP ensures that sound is very sharp and accurate.

 

Spc DSM (Direct Synchronization Method):

DSM ensures that delay between frames is not nore than 1 ms (mili second).

This ensures that synchronization between audio and video is perfect and the lips move exactly on spot.

 

 

 

Whole system is based on my own technology "Spc WCM" (Spc Wave Collision Matrix).

WCM works like a sea with the waves in it.

Where the sound waves colide there you hear the sound/instrument/voice .. etc..

 

In a simple words:

You have four speakers.

Front speakers play normal sound while rear speakers send special coded waves and then you get a matrix in an area that these four speakers cover.

Accuracy of that model is 2 milimeters .. so i can for example pinpoin an sound/drum/vioce in exact accuracy of 2 milimeters in an dot/spot where i want to be.

 

Audio is ultra sharp and it has pure physics in it.

By physics i mean that if for example you listen to an concert in an hall you will hear an echo with progressive falloff that'll give you impression of being there.

Ok.. enought tech talk .. here are the samples:

I recommend that you use headphones or a middle quality speakers with conjunction with creative Audigy2 ZS / X-Fi soundblasters.

 


 

So what are your comments .. suggestions ?
Yea, take pictures of your stuff! : )

here:



 

I appreciate your pictures SpC! : )

Damn SPC, I'm sure that you are going to be a friggin' millionair if you can develop all of this.

Send your Curriculum Vitae to Microsoft !!!


P.S. Nice sound


Few Screens so you can take a close look at the enviroment:




 


I'll post video later*

wow i missed something or?
The difference is impressive. The sound seems more clear and distinct. I hope you'll sell it to all those fucking cinema majors. Good luck, you deserve it.
But...there its question of frequencies....do we need a specific speakers system or did i miss something too? =P

No. Speakers doesn't matter what you need is my hardware X Drive II XD decoder that de-codes 4.1 audio from stereo source.


 

It sounds really good. I like it. Did you change the original frequency curve sound (sounds like high and low are up, and mediums down)? I can hear that when the guitare starts its sounds, it crushes the other sounds for a while, but maybe its from the original =D
it may be a silly question, but can one also normalize movies with your system? We have the problem that movies are very dynamic in volume too. if there are conversations, you can't hear anything, but the gunfire blows out the eardrums of the neighbours :P If there was a possibility to normalize a movie, so you can watch it without adjusting the volume every 5 minutes it would be great!
Woooow! lol! you solved the problem oO n1

 


wow. great stuff :) Some friend sent me a link to a barber 3D sound video really impressive too. Have you heard of these technique too Spc? It startled me.


Andi, you may try Media Player Classic (imho the best all-around video player) which has Sound Post-Processing effects included, one of them if I remember well is a "normalize sound feature" which I always thought to be some kind of feature to fix the problem you described. In my experience though, these problems are usually located on YOUR computer settings instead of the video file you downloaded on Internet. So maybe try to check your sound settings first and I wish you the best of luck to succeed in solving this.


 

ThX ben for your help and the nice words! i should have been more clear! i mean bought/rent dvd's, put in a dvd player and an additional use of a 5.1 Logitech soundsystem. I mean: is there a way or device that works like the normalizer in the windows media player classic (which i both use) or nero, where you can normalize soundfiles b4 burning? and just to add this little tip: dont normalize mp3s if you have more different kinds of music on a cd (rap/acoustic/rock or whatever) more silent music like acoustic/jazz/classic can't handle the normalization together with rock music for example! the more silent music will scratch/scrape/... after normalising it! :P

Updated info on some new technologies i invented ....

Normalization sux and also Very high dynamic sound sucks..


I like normal sound without any extrme volume changes.. if someone in film talks very quiet than the sound engeneer who mixed this film is total noob.


 

Yea i had that problem once andi, cant remember how i fixed it, look at your amplifier and its options maybe, try different in/out possibilities, and finally you could buy a compressor but ... thats expensive and for pros.

Yes it's called QSound but it's an virtual system for 2 speakers only i can do that very easly. QSound is very flat compared to my system (with my proper decoder ofcourse).


 

You want it you got it.

Processing of every single picture .. which means 25 pictures (frames) per second .. or 5460 pictures (frames) in 3min 38seconds (as long as this video is)

 

So for each frame (picture) i had to calculate sound, reflections, refractions and reverb.

 

Frame by Frame Processing:

I'ts coded in Spc X Drive II XD VIRTUAL (for two speakers)

 

For 3min 38secs i wasted approx 4 hours of processing.

I've also calculated focal length for every frame .. that means if a person is far/close we hear it far/close ...

Filename extension is *.sccac (Spc Crystal Clear Audio Codec XD PRO®) which can only be opened with winamp (drag and drop this file into winamp).
You can also rename it to .mp3 (will also work).


You must use winamp!.

Youtube erased all my videos without any explanation why so i moved to a slovenian site.

Enyoj my sound invention.



 

The quality is better there than in youtube. :) Nice work again ;) Sounds seems so clear with your "sound invention".

Svarog Told :

I spent a very good moment , nice work man

Weirdo! i first say that was a frequency filter choice, but indeed its more.
You are making a great work there and my job was sound engineer. GO ON!
