SpeakerWorkshop again

Dave Jones · 16th June 2004, 12:10 AM

I'm trying, once again, to use SpeakerWorkshop to measure some speakers. (It ain't exactly intuitive, to say the least, but the price is right!)

When I tried previously, I started this thread: software

I got some kind of results before, but I don't know if they were meaningful, and I can't remember exactly how I did it.

Reading the old thread, I see that some Audigy sound cards aren't up to the task. The manual that came with the board just calls mine simply "Audigy II". I cannot find any other model number. The OS (Windows) knows it as "SB Audigy [E400]". Will that one work?

I seem to remember also that connecting the mic to the microphone input on the sound card did not work. I've got a mono to stereo adapter for the mic, and I believe I've got it plugged into the line-in socket. The manual has no picture of the connections on the back of the card. The socket is the second from the right, and has a picture of a sort of spider web next to it. How can I tell if SpeakerWorkshop is even hearing the mic?

It's not; your mic requires power for the capsule unless it has a built-in preamplifier. The line-in doesn't provide this. The recommended solution is a mike preamp.

I'm using a mic preamp.

Perhaps I should be more succint. My questions are,

1) Is the sound card I have adequate?
2) How can I tell if the program is hearing the mic?

Under Menu > View, check VU Meter, it will tell you.

OK, good.

Well, step 1 would be to use a little toy program like sound recorder to make sure that you are, in fact, recording the output.

Beyond that, you are aware of Claudio's great guide, I would read through this until you understand it and come back with a specific problem.

For example, some poeple have trouble with delays, that is a problem that can be readily seen in the pulse response measurement. If you are having a particular problem, I suggest posting a screen shot and describing the problem. At the moment, I don't think you've provided enough information to offer any feedback.

Okay, I did that. Now what? I see six boxes come up with numbers in them. The numbers are not changing. Does that mean the program is not hearing the mic?

Run some measurement.

I don't know what you mean.

Yes, I am aware of the guide. Here are my specific questions: 1) is my soundcard adequate or is it one of the Audigy II cards that will not work with SpeakerWorkshop? and 2) do I have it hooked up correctly so that the program hears the microphone?

What information do you need? As best I know how, I've given the soundcard model number, and I've told you how I have the mic plugged into the sound card. What else can I tell you?

Dave Jones · 16th June 2004, 01:19 AM

I still would very much like to get an answer to my question about the sound card.

I do have it "listening" now. I don't get a very strong signal when I use "analog" input. When I use the mic input, I get graphs that consistently look like the one below. I don't know what to make of it. I can turn the treble all the way down, and the bass all the way up, and it still looks exactly the same.

I had the most terrible time with that software.... took me 40 bucks to build a nice jig and then my soundcard was not compatible, another 60 bucks for a soundcard that will work and i still took forever to figure the damm thing out. but it works well and it is free, i guess that is all that counts right? right?
