Hi Mark,

Out of curiosity I tried adding a 3 second delay to the Tapped Horn Wizard calculation time to see what would happen. Operation of the sliders became unworkable under those conditions. In most cases Hornresp simply locked up and had to be shut down and restarted.

Note that long front-loaded hyperbolic-exponential bass horns can have calculation times exceeding 10 seconds :-).

Kind regards,

David

Hi FlipC,

If you care to send me copies of both your Hornresp.dat data files, I will see if I can work out what has gone wrong (and attempt to repair the corrupted file).

My email address is dmcbean@bigpond.com

Did you install the latest version of Hornresp in the same folder as before, overwriting your earlier version?

Kind regards,

David

Excellent :-).

Hi FlipC,

Got the files okay, thanks. I will reply via email.

Kind regards,

Hi Sabbelbacke,

You're most welcome. Happy New Year! If you come across any bugs in Version 25.00, please don't forget to let me know :-).

I have already fixed a minor error I found in the Tapped Horn Wizard. (When the Eg slider is set to zero, the driver diaphragm should have a constant rms velocity of 10 cm/sec - this was not happening). The latest release is Product Number 2500-100105.

Kind regards,

David

Thanks for trying David. At least I'm not the only one with the thought as to if it could work. Is it a question of horsepower under the hood or the programing itself. I think you are using visual basic? Not that I can help in that regard. My high level programing language was Turbo Pascal!


Could it work with conical horns? That is what we all usually end up with when we build bass horns anyway. I make a conic that approximates what ever shape is designed.

G'day David

Another little bug in Hornresponse to report.

I set S1 to 0 in a tapped horn design (HR 24.00) and an error message came up. After closing the error message the program hung and I could no longer change any values. Perhaps you could add a very small value to S1 to stop the error happening at all.

Cheers

William Cowan

It's mainly a question of processor horsepower, although inherently Visual Basic is certainly a bit slower than Pascal (which can be almost as fast as Fortran).

Yes, and with any multiple-segment system having conical and/or exponential flares.

I have no plans at the moment to do anything about it though... :-).

Tapped horns appealed to me originally because they are very sensitive to dimensional changes, making the Wizard particularly useful in this case - I was really just looking for something to test out the slider concept.

Kind regards,

David
