Default Bug fix.

Hi David,

Thanks for getting it fixed this fast, right now all seems well. I'll let you know if I find anything else.

Regards,

David how difficult would it be to add in different acoustic environmental effects at will? For example a generic transfer function for a car usually rises 12db per octave from 80hz. An in home transfer function for a given room size can vary quite a bit. I guess I'm asking for a user variable filter to reflect acoustic environments. Make things easier when your modeling for certain areas.

That ties in with the standing request for "active" filters to mainly(for me) check cone excursion when high-passed.
So I guess it's a little harder than to add a simple frequency dependent scaling of the result.
Although you could do that with a spreadsheet by exporting the data from hornresp.

An alternative could be to just import a target function as a curve to model the response close to it. Like the inverse of a room or car. Might be a simpler solution as no change has to be done to the result.

An idea could be to have the result be automatically exported to a temporary .txt file on every calculation. That way a user app could read it and do any manipulation desirable with minimal interaction as you don't have to manually export every time.

@ David McBean and Mark
^^^+ 1
Would it be possible to have a direct entry box and or slider for the +3dB frequency and a pull down for the rate of gain say of +3,+6,+9,+12 dB per octave?

This would be great for a multitude of uses, for instance I use a generic 30Hz 6dB per octave gain when I model subs for home use.

The other feature I would like to see possibly even more would be a parametric HPF module having varibable Q, roll off rate, and -3dB frequency parameters.

I'll go crawl back under my rock now

Thanks for such an awesome design tool

Hi Mark, Dan and David_Web,

Sorry, but not even a cherry on top is going to help you with this one :-).

As mentioned previously, I am really only interested in modelling the horn loudspeaker itself.

Kind regards,

David

Well if we don't try you know we are not interested.

So cuz we try so hard means we are very interested.

Even without the bells and whistles Hornresp is one of the most accurate programs in my tool box. Thanks for all your hard work David. without you building horns would be a much tougher job.

Mark

Thanks Mark, your kind words are much appreciated :-).

I am currently working on changing the area slider scaling arrangements yet again, in an attempt to address the "ease of use" issue raised by David_Web in Post #1473, but without compromising the (seemingly conflicting) requirements of others. If everything goes according to plan an update, hopefully satisfactory to all users, should be released within the next few days.

Kind regards,

David

The Loudspeaker Wizard area sliders have been revised yet again. Changes are:

1. Area sliders are longer auto-ranging. They now have fixed upper and lower limits.

2. The stepping increment or "sensitivity" of an area slider can be changed by pressing the Spacebar key when the slider has the focus.

Could you please let me know if you find any bugs.

Kind regards,

David
