SignalScope / Export to Matlab/ascii on demo disabled? :(
« on: November 30, 2008, 10:21:45 AM »
It's a shame that export in Faber's is disabled, as there is no way of demonstrating to those powers that be that think that OS X is dead, as a platform for serious (audio) engineering.

Displaying nice Apple Quartz graphics is one thing, but being able to process the results by the scientists here with their copies of Matlab and Excel is another. This may sound like a lame excuse in avoiding purchasing copies of the software- it is not. It is because here, in cold wet England, it is still Windows XP that is king, and Mac's are for the ladies (which we all know is complete bol****s). That means, I have to purchase any Mac software before the company I work for, will touch it.

SignalScope / jumpy display. Why? How do I turn it off?

In the y-axis of the FFT window (magnitude), the display jumps up and down. Is there any way to stop this?



SignalSuite / Re: Better frequency control input needed

Sorry for the late reply to your reply here Ben.

Yes I agree.

Also, although, not as important, but nice anyway would be a reference button that a predetermined frequency with amplitude setting (memory button!) could be applied- like 1kHz @ 1vpp would be extremely useful.

Do you know if the iPhone/iPod outs are consistent, or do they vary (within a certain minute tolerance) from model to model? (I'm guessing because they're Apple made, they are spot on?)

SignalScope / Re: Intervalometer?

that idea sounds great.

I'm presuming that you intend to merge the two apps (Scope and Suite) together?

If this is the case, it would be even greater if SignalScope could also produce a CSV file too? Or is that just asking too much? (I'd happily pay for this).

SignalScope / Intervalometer?

Hi Ben and forum!

I dunno about you folks, but I could really use an intervalometer on SignalScope for iPhone. Then I could leave the iPhone in the anechoic chamber with a stopwatch (the wall clock!) in the control room (more a cupboard than a control room!!). then I could step the test osc every say 10 seconds, and signal scope could produce an image file for each step.

It's also a great way of getting a reading of a room without my heavy breathing. ;¬)

What do you think?

PS is there also any chance of SignalScope being able to produce plots with a white line as well as the current red default? Because if the image file is inverted, I would get a black trace (instead of grey) on a white background (which is easier to see).


SignalSuite / Better frequency control input needed

Although as it stands, SignalSuite is very good, it could get one step better by introducing a better way of inputting frequency steps- like for eg, the thumbwheel control which is used to set dates in so many other iPod Touch/ iPhone applications. Then I could increase or decrease in frequency more accurately.

Hi Ben.

Thanks for the reply. Apparently the Outline turntable that we have, rotation can be achieved simply by sending a signal (+5v?) via its parallel port interface. I know though that this older analogue model has been superseded by a newer high-tech model that uses ethernet connection.

Polar plots aren't too much a problem- and yes scripting the toolbox would be the best thing.



I've been looking at your software (which looks good I may add) as I'm looking for a portable solution, that also runs on a Mac to use alongside the testing of our product, a flexible electro-static speaker surface (which we also have a worldwide patent on).

Currently the set-up in our studio consists of a Brüel & Kjær mic, and Outline parallel port driven turntable, and the ancient, but very capable DOS driven DRA MLSSA software. This is equipment which was bought by the company before I was appointed as technician, and it's pretty fair to say that this set-up is considered the 'industry standard'.

However, what I would like to know is how is it possible to do polar directional response plots (automated would be really nice) using the Faber software? If the Electroacoustic toolbox could replace MLSSA (the w98 computer that MLSSA is running on is getting pretty old and tired!) both inside and outside of our testing chamber, this would be grand. :)
