Inovonics 500 audio analyser....??

Posted: Sat Jul 08, 2006 12:32 am

I have the chance to buy one of these. (Real Time Spectrum Analyser,
RT60 Analyser, & Pink Noise Generator)
For about $150....no manual, no mic.

Any recommendations?
or would a dedicated software RTA be the thing to get. (btw, I have Wavelab 4).

thx

redrabbit, for what purpose you intend to use this real-time spectrum analyzer for? If you to live PA work and you want to evaluate your playback system, then you would need the recommended matching and calibrated microphone. If you are using it to simply identify feedback frequencies for a live PA application then generally any reasonable condenser microphone should be able to display a feedback frequency spike.

Conversely, if you just want to look at a single channel of an output from your sound card of some recorded material, you will merely need a patch cord. If you have a real-time analyzer built into your software, there really isn't any need to have this device. In which case I would recommend you spend your $150 and by your self something useful like a microphone or software plug-in maybe a book?

At least it's not a rectum analyzer

What do you plan to use it for? A typical RTA is not very useful for small-room acoustics. I use the ETF software which costs the same $150:

There's also the Room EQ Wizard which is free but a little less capable:

In some ways less, in some ways much more.

Thanks.
Usage...I was thinking for testing "small" room acoustics, but as Ethan pointed out, the more appropiate software is the same price.
I'll pass on it, but if someone else has a need for it, i can pass along info so they can buy it instead. Let me know, here.

David,

> In some ways less, in some ways much more. <

Maybe I need to read up more on their site. I REALLY wish the program just ran native under Windows! I'm not willing to install a 110 MB Java runtime library just to try it out.

But what does REW do that ETF doesn't? I know it's probably easier to use, at least at first. But it does it actually have features that ETF and R+D don't? Go ahead, give us a sales pitch! Very Happy

I'll invite the creator here. He'd say it better than I would.

Hi Ethan,

I wouldn't say there is much of significance that REW currently does which ETF/R+D doesn't as far as acoustic measurement goes. I think it is easier to use, and makes it easier to analyse the measurements through better graphing, better interaction with the graphs and perhaps some better plots but there are many (acoustically important) things ETF does which REW doesn't. REW does also provide programming of some equalisers if that is of interest, don't know if Doug has included that yet. I am in the midst of preparing the next release of REW which will improve on a number of areas so perhaps you might like to check that out when it gets released.

Not exactly a sales pitch, but then I do give the software away Smile

BTW, I haven't forgotten that I owe you a set of measurements of equalised and unequalised room responses over a range of positions, just struggling to commit enough time to it. I will get it done though!

John,

So I hear. As it happens, a good friend of mine has REW and loves it, and I'll get a demo this weekend when I go visit him.

As you know, I'm not a big fan of using EQ to counter acoustic problems. But it didn't affect my opinion of R+D and it won't with REW either. Very Happy

I probably will. As I'm sure I mentioned before, I'm not keen on installing a 100+ MB Java runtime library just to try REW. But I recently installed Windows XP SP1, which I plan to remove soon via Ghost to get my C: drive back to where it was last week. So maybe this is a good time to try REW! When will the new version be ready? If it's fairly soon, I'll hold off on restoring my hard drive.

You are a true mensch. (Where's that Angel smiley when you need it?) I used to do a lot of programming, and I've written a fair amount of freeware myself. It's a noble cause. Especially great software like REW.

Whenever you get to it, I'll be happy to see the results.

Will be about 2 weeks.

John,

> Will be about 2 weeks. <

I'm sure you have plenty to think about, but if you happen to remember please send me an email or post here when it's ready. You can email me from my company's site.

By chance, yesterday a software company sent me an evaluation copy of their latest and greatest creation. When I went to install it the program said it also needs to install .NET 2.0, which is another big runtime library. So when REW is ready I'll try BOTH programs, and install BOTH runtime libraries. I can always use Ghost to go back if needed.

Thanks.

Just a curious question.

I see lots of alternatives presented. But does anyone knows what this Inovonics 500 audio analyser.... is all about?

Should have been good that redrabbit gave a link himself.
Doesn't seem easy to find.
Smile

That could as well be the super bargain of the century, as a useless thing.

I could not find much info on the net...perhaps a picture, Although there used to be one on Ebay, for about $250 US.

The one I know about , for sale $150, (if they still have it) is at:

http://www.apexelectronic.com/index3.htm

Call, talk to "Anders".
Also, he has a friend who knows the unit, and can possibly copy the manual.

The required J2SE Runtime Environment 5.0 Update 7 has only 18 MB.
