Hi GM,

It is not possible for Hornresp users .... to choose a different data file to load.
It is possible

Greets!

Actually, I ran out quite awhile back, deleting a bunch on several occasions. Lately, I've just been writing over them, but at some point I'm going to be down to a core driver database, so thought I'd ask.

Since I calc most designs, it's just a matter of inputting the results, so don't have that much time invested in them. The sheer quantity is due to the inverse square rule of the less you charge, the exponentially faster your 'business' grows, so doing sims at no charge, my email Inbox is never empty, though it has tapered off a bunch since you added the slider TH Wizard.

I get enough grief from one, so don't want to 'double my trouble'.

Computers aren't my 'thing', so will this work, or is this a 'tongue-in-cheek' remark?

Thanks, I downloaded it awhile back just in case I ever needed it, but didn't consider it would be of any use for my situation, though if I can have multiple HR program folders, then this should allow me to export/segregate by type, i.e. TLs, FLHs, etc.. Then the only downside is I can't run but one folder at a time.

Or, since I have multiple partitioned HDs, if I put the folders in separate partitions can I run them simultaneously?

Hi GM,

Hornresp requires that the Hornresp.dat data file be stored in a folder call 'Hornresp' located immediately beneath the root directory of the drive that the program is installed on.

If you have multiple Hornresp.dat files then about all you can do is to save them into individual archive folders and copy the file you require back into the program's 'Hornresp' folder when you wish to work with it.

Not an ideal situation, I agree, but I am reluctant to increase the data file record limit as operationally things would tend to become rather unwieldy. I suspect that very few users (apart from your good self) will ever get anywhere near the 999 limit anyway :-).

Kind regards,

David

use dos to swap folder names back and forth.
Have two or three icons, each uses a different dos file to use the folder you need.

Default Hornresp Version 21.40

Hi Everyone,

I managed to find a few spare hours over the weekend. Hornresp can now calculate the impulse response for any horn loudspeaker system. Results are slightly different to those generated previously, but should be more accurate.

Also, the limit on the maximum number of data records has been increased to 9999 - hopefully this will be enough even for GM :-). With 9999 records, the Hornresp.dat data file size is 3526 KB.

Version 21.40 refers.

Kind regards,

David

Default Hornresp Version 21.50

Hi Everyone,

To make it easier to search for records in what now can potentially be a very large Hornresp.dat data file, a filter has been added to the Find tool. For example - to list all tractrix horn records select 'Tra' from the filter drop-down box, to list all tapped horn records select 'TH'.

Version 21.50 refers.

Kind regards,

David

Thanx a lot david, this comes in very handy!!!! As alway it´s a pleasure to see your ongoing support if the community with hornresp!!

I did some comparison to akabak and LSPCad regarding impulsresp.

A single TH with a 15":
Click the image to open in full size.
Exportet to Akabak, I get this (time impuls, 0-40msec, normalized y-Axis):
Click the image to open in full size.
Same but with time step:
Click the image to open in full size.
Akabak is capable of looking at a cutout of the frequency range if only a small range is of interest (as with subs).. Same input data, but time step is derived from about 30 to 350 Hz:

Resolution of course is too low now, but raising the sim-points/oct gives more resolution in the iFFT calculation.

Comparing to another software:

doing a simple closed box with the default driver:

Thrown into LSPCAD:
Click the image to open in full size.
LSPCAD couts of everything pre to 0ms and leaves out the distance between virtual mic/ears and the transducer, which results in a offset from a few ms to the left and the ommitance of the transient oscillation before 0msec.. But otherwise both results seems comparable.

Taking the same enclosure, just adding a port... before hitting the "compined" response, we get something quite similar to the closed box (which is plausible, except for the notch at the tuning frequency of the resonator, the box stays the same.. )
Click the image to open in full size.
After adding the port response with "combined response":
Click the image to open in full size.
Typical ported Box, seems ok.

Doing the same Box in LSPCad:
Click the image to open in full size.

Same difference on time-axis as above wit the CB, otherwise the same except for the ripples which LSPCad simply seems to smooth out...

Looks good
