My trusty old (about 15 years) MLSSA system has to go - that's the card and
software, because the portable PC I was using for it became unreliable. It
would still be good for a speaker designer who could find an old PC with an
ISA slot, running DOS. If you don't know what it does see

You must be talking to me! My post of 28 January has expired from the
news server that I use, and I'd forgotten all about it. Yes I did sell it,
got a better price than I expected thank you.

Sorry, no. But why do you want MLSSA specifically? Much as I liked many
aspects of MLSSA, there is a lot to be said for using a system that can work
on a modern laptop PC. And of course even the best electronic devices will
give up in the end. I would not have bought a 15 year old portable PC to
carry on using MLSSA, even if one had been available.

Hi, i've used MLSSA previously and found that some of the measurement
ability such as 'group delay' don't seem to be present more modern systems...
can you recommend any alternative systems that you feel would suit a small
budget?
thanks in advance.
Lawrence.

I'm using Liberty Praxis. It does appear to have a group delay option,
although I've never tried it. Generally I find it technically good,
although I personally find the user interface awkward and it takes getting
used to. I also think it has a few bugs although these probably wouldn't
affect loudspeaker measurement. One interesting thing about this software,
is that almost all functions can be used from the free demo mode provided
you are prepared to work from recordings rather than use the software to
output the test signal and make the measurement directly. It's obviously
not a fast way to work but it does allow you to try out the functions and
get a good feel for the software. Of course one thing that wouldn't work is
group delay, because using recordings loses the absolute time information.

I have to say you will find it slow to use compared to MLSSA but that
probably applies to all modern software! One thing I miss a lot is the
ability to set a post-processing option (for example smoothing) and have it
automatically applied to all measurements. Another is the ability to hold a
trace on the screen for comparison, without having to save it to a file and
re-load. But Praxis also does things that MLSSA can't. If you want to
