Video Tutorial Online! Switching To TIMED Kernels

Post by david1103 » Fri Aug 31, 2012 11:24 pm

hello,

i was asked via PM some questions on switching to using TIMED kernels for better sound quality. I offered to do a video tutorial and blog article, so here it is!

http://www.learndigitalaudio.com/blog/n ... ed-kernels

there is an audio example in FLAC to download too.

if there are any errors please let me know and i will correct them asap.

it took me the whole day. i hope it is useful. if you like it please consider joining my email list or clicking 'like' on the big facebook box on the right :D

I will do more of this type of thing if i get good feedback, but it takes forever! enjoy...

Big THANKS for the tutorial AND for doing a video.

The included test audio as well.

So, like many, I too was following the 'Timed Kernal' discussion ... including the apparent 'quality' changes.

First ... if it is at all possible ...

Can you supply the original, unaltered audio clip along with the 2 processed files ?

There is NO question that the 2 processed clips have significant differences, but without the original audio to compare, it is not a complete test.

Maybe not the best choice of wording ... but, I'm wanting to be able to critically compare ... of course, your tutorial has made it much clearer for me to do my own testing. Prior to this, I've been quite reluctant to mod Nebula at this point [mostly due to so much other testing that I'm involved with].

Anyways ... thanks again for doing this! I'll look forward to any other postings you may do!

Again ... to really complete this comparison, the original is indispensable :)

Thanks!
Sincerely.

oh BTW ...

This may very well make me REDO all of my previous work :shock:

Great job man! I wish you would consider writing a good manual for Nebula. Why? Because to me although I appreciate their effort, the existing one reads like a Japanese manual translated into English by a high school student. I actually did try to read it but just surrendered to using the plug to as is.

This should be stickied. Also if you want to do a chain of this, get nebulaman. Takes the headache away of having to freeze everything.

Indeed, but there is more to getting higher quality than just these mods , these are mods I stated way back in the transient quality thread . A manual maybe a good idea . If you want higher quality again you should be using lower buffer settings ,if say you go from 512 samples to 128 you can hear a big leap in quality again . You can get down to 16 samples if you mod the xml ,But you can only do this probably at 44.1 to 48khz.I use a lower buffer setting in favour over pure timed and use splithd , increase to 10ms on the timed side and reducing freq by the same amount.It is a better balance of quality vs cpu this way .Just find out what is best for your setup

I finally moved from the sidelines into the active arena of modding NEBULA Kern parameters.

Combined with this tutorial and the various discussions on the topic, I've been testing various libraries, along with comparative A/B'ing.

For my audio source, I've been pulling up several tracks from my 'Audiophile' collection. My initial testing is mostly on modded preamps, and listening to the sonic changes they do to this highly regarded masters.

Not ready to post a 'final conclusion', as there are several outstanding questions regarding the initial parameters that the library came in.

There is also a question as to procedure ... especially this:

I've NOT been saving my changes [via Nebula] as has been stated by others. I've modified a preset, and then save the project as a REAPER file. When I 're-load' the project, my modded settings are still there.
BTW ... I DID make a NEB Server duplicate and modded its' XLM file, so I have 2 versions to compare.

So ... I still 'hear' a difference ! Am I doing this right ... or is my imagination hearing things :|

Second issue ... and this is a ROYAL PITA !!!!

Specifically NEBULA on XP32-sp3 ... has crashed so many times just clicking on the KERN button ... it is ridiculous :evil: After, maybe 6 or 7 crashes like this ... then FINALLY it starts to let me edit that screen.

NOTE ... I've already shipped my NEBULA package up to 'E', and he went through it and fixed things from whatever my original, un-modded' install was.

I'm running the 'TIMED' version as a 'dedicated process' in REAPER just so that only the plug will crash.

'G' ... I've read your latest posting ... know you're busy ... know you've burnt out a NEB dev ... but please, this is tough to deal with in a commercial environment, and extremely NON-productive!
[also ... the graphic crashing of NAT and not being able to spread the interface across dual screens.]
oh ... and I'm not gonna mention the garbled numbers in NEB's fader section :twisted: :lol:

alright ...sorry for sidetrack rant !

Later, I'd like to discuss interpreting the original Kern settings and how to apply them to the TIME mod.

Don't know if this is the proper thread for that ?

Sincerely.

THANK YOU everyone for your kind words! :D I am very happy people are finding it useful.

I will reply to people's posts:

My intention was for people to only focus on the difference between the TIMED and the FREQD versions, so that's why i didn't include the original. I don't think the choice of preamp was the best for the source, its just it worked well for the example.

I have uploaded the untouched source for your listening pleasure:

but won't update the article as i still think it would distract people from the goal.

Lol! I am very flattered, that would be a seriously big job. I am happy to take on any paid work i am offered ;)

This is very interesting, I would LOVE to hear from giancarlo on the subject.

Could you make any example sound files? You are welcome to use my untouched bongo loop i just posted to keep things consistent.

Anyone ready yet to comment on the differences between the TIMED and FREQD examples from my blog post?

it's a good tutorial, david! seems to pretty much cover all of the important angles on the topic, and so if anyone is confused about the whole timed/freqd mode thing, they should check this out.
good job!
