Hello colleagues, for a few days now the engine market is getting into full swing and as in everything, the competition always makes everything improve. In the end we are nothing more than freaks of the best possible sound and by briefly searching the internet I have found several practical tools. The first is a classic that works on Windows without any problem which sets several ideal audio references for our test discs. working with several DIN and with frequencies of 3150.
WFGUI

The second option that I have found is a somewhat more modern one in which we need to put a WAV file to make the measurements, I leave you the link where you can see more information and the download link. Based ON AES6.

The third option is paid, even so it promises to be one of the essential tools to make many serious measurements, apart from wow & fluter, we can measure coging which is quite necessary for our motors, apart from being a classic among measurements for cassettes. Its name is NAK T-100

I hope it helps creators, restless people and above all so that we improve the quality of what we are passionate about. The world of vinyl.
Receive the greatest desire for improvement,

Re: Tool for serius measure wow & flutter & more
Fantastic. As a restless spirit, I'm always happy when a topic like this comes up, one that I have to reinvent myself in. Another rabbit hole. Thank you!

Here's a web browser W&F application. It complies with AES6-2008 / DIN 45507 / IEC 60386 / CCIR 409-2 standards. It runs completely within your web browser and processes whatever files you give it right on your computer, tablet, or phone.
It's here: W&F Analyzer
If you don't have your own W&F tracks recorded and want to play with it, this link will launch it with one of my test files.
I'll be adding plot/report downloads from it in the next week or so. I ran over 50 synthetic test and real files through it. There are some edge cases for low frequency tracks and severe wow (3%+), but I believe it to be very accurate for all but pathological cases. The impetus for its creation was the ability to measure the low frequencies of DD motor FGs. It was designed to support carrier frequencies from 50Hz to 5kHz.
Geek stuff here.
