Lite Converter 1.0 Automate Kontakt Lite Version Library Creation WiN screenshot
Script | KONTAKT Lite version tool | 29.17 MB
This is a CMD / powershell script which will extract NCW files to 24 bits WAV files, convert them to 16 bits with a high quality dither, and recompress to NCW files with a single click.

Well, actually you need to double-click the file but still, that's easy.

The script is written in Powershell and batch run some tools that will do the painfull and time-consuming conversion job for you.

You just have to extract NKX files into source folder (if necessary), and run the script to see the work done.
A limited documentation is provided, but if you need detailed steps for extraction or to get rid of a microphone position, I recommend you to read the excellent Rollerball's Tutorial
This script is not really a tutorial but a tool to make things easier and faster.

For a library with 24 bits NCW samples that are not packed in NKX containers, this is as simple as dropping the entire library directory in the source folder and run the script.
You will get a new folder with a lite version directly usable.

A portable version of Double Commander with inNKX module preinstalled is available along with the script if you need a tool for NKX containers extraction.

The script might be pimped or optimized, if you make some good optimization, please share it so I can update the script.

Requirements
Windows 64 bits (tested under Windows 10, should work with 7 and 11)
Script is in english, french version provided, just change script name in LiTE_Converter.cmd
May work in 32bits by replacing ReSampler x64 -> x86


For best performance, you need to use 2 different drives, SSD are a lot faster too.

Can you make one for Mac to just extract and repack (without 16 bit conversion to just separate the mics]. It's too much of a hassle to get Crossover & then Total Commander. I did remove extra mics for Cinematic Studio Brass & Solo Strings but that was too much of a hassle I wound not want to repeat.

Unfortunately no, I cannot even do it for Windows as there is no command line tool that handles NKX containers extraction. The only way is to use the TotalCommander extension inNKX.

I searched a lot, no other software seems to exist for NKX extraction.

Try asking Fred Bloggs on sister site, he can script for mac, has already done Kontakt Library Utility (KLU).

OK sorry, I forgot that most users don't use powershell often, I will modifiy the launcher.
Please, edit your LiTE_Converter.cmd with a text editor (notepad) and replace the line with this one : 
powershell -NoExit -ExecutionPolicy Bypass -File "lite_converter_ENG.ps1"

Remember to edit the paths variables in lite_converter_ENG.ps1 before running the script.

Thanks for amazing tool! Unfortunately I am getting an error as below for half of libraries. Here is Symphobia 2 example:

Cannot find path 'C:\temp\w' because it does not exist.

Is your path correctly defined in variable?
Please check the $wavDir variable, the value is probably wrong.
defaut is:
$wavDir = "G:\temp\wav24\"

The safest is to change drive letter only (this is a temp folder which will be deleted at end), and for this variable specifically you have to check a backslash "\" is present at the end of the path.

Some commands are built with these strings and you have to keep the original syntax intact.
I'll try to improve that in a future version.

yes path were denied in variables also I make sure to include slash "\" but still the same. For some libraries It works for some unfortunately not. As a result it is just moving the original library to new lite folder and all works very quick because it is not really converting the library. Below I am pasting all the response I've received:

Can you send me (PM) your variables section please?
And also the full path to the samples in source folder.
Did you try without the whole libray folder, maybe with samples folder only?

EDIT: OK, I definitly believe that you didn't extract NCW files from NKX containers as I read your prompt:
Project Sam - Symphobia 2 Library
130  total files.
Total files size :
22,35 GB

Symphobia uses thousands of sample files, not 130, so you missed the first step. As I stated it in documentation, you can drop a full library folder ONLY if samples are not packed into NKX containers and NCW format.

To convert Symphobia you have to use DoubleCommander (see first post) and extract all files before droping the lib in source folder.

Script updated:

- Added more readable file variables.ps1 for variables to prevent modifying main script.
- Added NKX files presence check, fail conversion if detected.
- Added powershell execution-policy bypass in command line
- Added warning and start confirmation
- Updated documentation

How does it handle 32bit Float samples? Some libraries have a few scattered 32Float samples in there sample pool.

I've experienced that when I've used NCWCon to convert libraries, those samples were converted into distorted "regular" 32bit samples. Not sure if there is a way to fix or at least detect it but if you automate the conversion from 24bit ncw to 16bit ncw you might not find out about this until you actually load one of those patches containing a samples or two that are completely distorted

I have no idea but if this is due to conNCW, the issue should be present as the script rely on it.
But I could maybe add a check to avoid converting such samples.
I would appreciate an example sample for testing purpose.

It looks like it's better to avoid spaces in script path.
I will fix it if I found where is the bug.

Script updated:

- 16 bits wav files are directly copied to destination and not only droped.
That way, 24 bits libraries that contains some 16 bits samples won't generate a bad count error during conversion.

- File count is displayed and logged in case of difference.

Links are updated in original post (don't use audioz mirror as it's outdated).

Please, feel free to give some feedback and report errors as needed.
