It's hiding in the middle of the first tab. You'll find it.

I wanted to work with them to impliment my polar amp plotting directly into the program. Holm thought it was a good idea, but didn't have a programmer to work on it.

gedlee, just put a thread if anyone knows him here. He has really done a good job. Indeed the tool was gr8 but had few shortcomings. but as a free software and his efforts. that was really worth praising. I use this tool as a primary measurement tool.I liked it much.

I hope someone here knows him. and would be able to reconnect to him.

It depends what you want to measure, really.

From here: Getting Started in DIY Speakers - undefinition

"But how do I measure?" is the question on so many intermediate speaker designer's lips. So far, I haven't found a decent set of instructions on the internet on how to measure loudspeakers that wasn't either confusing, or contained too much, or not enough information. However, there is an excellent book written by Joe D'Appolito titled Measuring Loudspeakers, which really fills you in on everything you needed to know on measurement, and also contains all sorts of interesting asides about speaker design. It does require a decent understanding of loudspeaker design, though--that is, you've read and understood Ray Alden's Speakerbuilding 201 and/or Vance Dickason's Loudspeaker Design Cook Book.

See here also:

Measuring Loudspeakers, Part One | Stereophile.com and

Zaph|Audio

Also helps to read the user manuals of various software; see the manuals and papers here Bodzio Software (for SoundEasy). And if you have Speaker Workshop, there's a complete walk-through of a speaker design example in the help files.

Changing the signal length in the signals tab will change the sweep rate.

I realize this thread is sort of dead (as is the development of holm?) but I'm hoping there are still some experienced people following this.

What I'd like to know is how to organise my measurements. All the measurements slots have filled up and now I'd like to save a selection of the measurements to a file. Any way to do this?

My normal workflow involves measuring new drivers and I need a way to archive the old measurements in groups. Is there a way to do this?

I looked into the option 'organise measurements' but it does not seem to do anything? It's allows me to select the measurements I'm interested in but after I press 'OK' nothing happens?

Thanks for your time.

is very helpful and highly recommended.

The book goes into GREAT detail on how to conduct the tests. Make sure the book comes with the supplementary material that was sadly left out of the book; what the tests mean.

How does one tell if the supplementary material is included? Is it a newer edition or does it include a CD or something. The ads on EBay and Amazon don't mention anything

You can save everything as a zip file. Then delete the records that you don't want in a group and move the ones that you do to the top in "organize". Save this new file as a zip file with a new name and in a directory that means somethnig. In other words use Windows directory structure to organize the groups of records. I have hundreds of measurements organized this way going back about 5 years. Now you can go back to the original zip file with everything and do the same thing for the next group.

Thanks Earl, I suppose that is the way to go.

I thought I had overlooked something but apparently not. Too bad the software is not open source...

[gedlee]

The software is not a database for records. You have to do that some other way outside of the program.
