Just to let anyone who is interested know that I've finally collected
enough 'round tuits' to produce publically available versions of the 'IQ
Test' software. The programs can now be found at

http://www.audiomisc.co.uk/software/index.html

(Just scroll down to near the bottom of the page to find the links to
archived versions of the software.)

The IQ Test lets you make very precise 'wow and flutter' timing and replay
rate measurements. An example of their use can be found on the webpage at

http://www.audiomisc.co.uk/Linux/Sou...ForChange.html

The compiled versions are for RO and ROX Linux. But the source code is
provided in case anyone wants to examine/modify/port it for their own use.
The ROX Linux version can also easily be run on Linux systems that don't
use ROX Filer.

Slainte,

Jim

Thanks Jim,

From the subject I initially thought you were offering Mensa memberships :-)

Afraid I am a member of Densa. The organisation for those *not* in Mensa.

Must admit one of the reasons I liked the 'IQ Test' label was that I think
this approach is cleverer (more general) than the 'J Test'. But it was
mainly named because it is an application of IQ modulation/demodulation.

I'd also write Mac and Windows versions, but since I don't use either very
much it isn't on my worksheet. If anyone else wants to do so, please do.
The only person I know who writes audio software for Windows doesn't use
'C', [1] so we lack a common language. :-)

FWIW I'm also wondering if there an optimum way to apply this to LP
for accurate wow and flutter measurements. Alas, since ye old 'quadrophonic'
have passed test discs these days don't seem to have 'IQ like' test
tracks. But there may well be a decent way to mimic this using the usual
3k-ish tone on a test LP.

Slainte,

Jim

If you ever hope for this code to really see the light of day, you'll figure
out how to distribute executables that run under Windows with no fuss or
bother. The tool has been needed for at least a decade, but as far as 99% of
everybody goes, it still doesn't exist.

Not quite sure what some parts of your comments refer to TBH. The source
code is supplied in GCC 'C'. So anyone who has an interest, and knows how
to use GCC and 'C' should easily be able to do a version for Mac or
Windows. Then release that if they choose for others to use.

My understanding is that pretty much all that would be needed is
to change some of the file naming conventions and a few similar details
which I'd assume a Windows or Mac user would spot. Then use GCC.

That said, I'd expect anyone with a serious interest would want to develop
their own code, add their own bells and whistles, and only use what I did
as a sort of 'starting point' since I'm not a particularly good programmer.
In programming terms they code I wrote is fairly simple stuff.

I appreciate that there will be people who want to use such a program but
don't know how to write programs themself. But I don't use Windows or Mac,
and have no real interest in doing so personally. And I'm pretty much
settled on programming with 'C/C++'. So far as I am concerned anyone who
wishes is welcome to examine or use or adapt the source I've provided, or
use the ideas.

I wrote the programs prompted by my own interest and wish to try such a
test and see what it might show up. I'm not trying to sell the programs. So
far as I am concerned I'm quite happy to make my code freely available for
anyone else who finds it of use/interest. If someone cares to make a
Windows and/or Mac version, that is fine with me. But not something I'm
personally wanting to spend time on. Have other things to do.

BTW I have also contacted someone who *does* use Windows and writes some
programs. So maybe he will produce a Windows equivalent. But that is up to
him, not me.

BTW2 I've recently updated the Linux version of the analysis program to
squash a minor bug and add a useful feature that users probably won't
even notice. :-)

All of that said, TBH these days I'd have thought that anyone with a
serious technical interest wouldn't be deterred by perhaps simply putting
Linux on a (perhaps older) box, or dual-installing it beside Windows. Not
really rocket science these days.

Slainte,

Jim
