Greets!

You're welcome! Thanks for the explanation.

No such luck. I 'added' a NEW RECORD of an existing design (attached), converted it to an EXP, clicked FIND to save and move on and instead got the same error message which of course closed HR when I clicked OK. Reloading HR shows that same as last time, it didn't save my new sim.

Hi GM,

Thanks for this. No matter what I try, I cannot generate the error you are seeing - it's quite frustrating, really :-). I will have another close look at the code over the weekend to see if I can find anything that I think might be capable of causing the problem.

Has the error only appeared since the record capacity was increased to 9999?

If anyone else has experienced a problem similar to GM, could they please let me know. Thanks.

Kind regards,

David

Hi Eva,

Thanks for the comprehensive background information.

Just to clarify, the system phase response model used in Hornresp takes propagation delay into account intrinsically as part of the fundamental calculations - it is not something that is added in separately. I am not sure how it could be satisfactorily isolated out and removed to reduce wrapping without corrupting the overall results. Wouldn't this in effect be changing the system phase transfer function to something that it is not?

Kind regards,

David

I think that the easiest solution is to add a manual propagation delay compensation dialog or slider allowing the user to enter any value and then watch the resulting phase and group delay plots with this delay substracted.

By the way, this allows to find out the theoretically best delay compensation to be used with DSP crossovers (which may include some group delay correction in it too).

Greets!

Me neither since I posted it. Understood.

Correct.

GM

edit:

Hmm, I wonder...........I made it happen again as soon as I created a new (ADD) design from a pre 999 one, modded it, then clicked on FIND, but haven't been able to repeat it since the re-boot nor does copying a > 1000 design trigger it (so far). Seems strange that I could only do it once in at least a couple of dozen tries........

Hi Eva,

Not sure what this would mean in the case of a tapped horn, where multiple acoustic paths exist. I think I will leave things just as they are for the time being, at least until Jean-Michel has had a chance to investigate the feasibility of un-wrapping phase.

Kind regards,

David

Hi GM,

I had another good look at the Hornresp code on Saturday but still couldn’t find anything wrong. Since I cannot generate the error, and because it only seems to occur intermittently for you, I have added some special error trapping code in an attempt to identify what statement in the program might be causing the problem.

Could you please download a copy of the latest release, and if you get a message similar to the following at any time, advise me of the error code and statement number.

'Subscript out of range' error 9 generated by statement A72.

(In the above example message the error code would be 9, and the statement number would be A72).

If you still get the original error message rather than the one above, and no one else reports a similar problem, then it probably means that the error is machine-specific, and that there is little I can do about it. Would your computer have an AMD (Advanced Micro Devices) processor, by any chance? Also, what operating system are you running?

Kind regards,

David

Greets!

Interesting, I started to ask if it might be machine specific and HR just a 'trigger'.

According to the Belarc Advisor software it's a 2.40 gigahertz Intel Pentium 4 running Windows XP Professional Service Pack 2 (build 2600).

Anyway, I've DLed the latest version and will let you know what, if any more problems/error messages pop up.

GM

OK........... just got a 'runtime error 9', but without a 'statement' while moving back n' forth between several different TH sims.

Gotten it several more times without a 'statement', something doesn't like me using HR's FIND feature.............
