Inspire 4.1 4400 Signal Processing?

So Ive got this very nice set of speakers here I bought a while back. They are the inspire 4.1 4400's. Today was actually the first time in a long while I had them hooked up to a 2 channel source while leaving all 4 satellites connected. I had them hooked up to the living room tv which gets its signal from a digital cable box through the standard composite cables (Yellow, White, and Red). The tv does have an "enhanced sound" feature which is enabled.
But back to my original question: As a guy who drools over technical details, Im curious if these speakers have any extra signal processing when receiving a basic 2 channel signal? Because I noticed at points throughout the day where the rear satellites would sometimes sound like they are receiving different signals than the front satellites and than at other times all 4 would be identical.

shof55,
Here's an example of what the cable is.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.
In particular, I am analyzing the example "Even Angle Reference Signal Processing (Digital Tacho, DAQmx).vi", whose documentation I am reproducing in the following:
DESCRIPTIONS:
This VI demonstrates how to extract even angle reference signals and remove the slow-roll errors. It uses DAQmx VIs to acquire sound or vibration signals and a digital tachometer signal. This VI includes a two-step process: acquire data at low rotational speed to extract even angle reference; use the even angle reference to remove the errors in the vibration signal acquired at normal operation.
INSTRUCTIONS:
1. Run the VI.
2. On the DAQ Configurations tab, specify the sample rate, samples per channel, device and channel configurations, and tachometer channel information.
NOTE: You need to use DSA PXI-447x/PXI-446x and PXI TIO device in a PXI chassis to run this example. The DSA device must be in slot 2 of the PXI chassis.
3. Switch to Extract Even Angle Reference tab. Specify the number of samples to acquire and the # of revs in reference which determines the number of samples in even angle reference. Click Start to take a one-shot data acquisition of the vibration and tachometer signals. After the acquisition, you can see the extracted even angle references in Even Angle Reference.
4. Switch to the Remove Slow-roll Errors tab. Click Start to acquire data continuously and view the compensate results. Click Stop in this tab to stop the acquisition.
ORDER ANALYSIS VIs USED IN THIS EXAMPLE:
1. SVL Scale Voltage to EU.vi
2. OAT Digital Tacho Process.vi
3. OAT Get Even Angle Reference.vi
4. OAT Convert to Even Angle Signal.vi
5. OAT Compensate Even Angle Signal.vi
My question is: How is the synchronization produced at the time of the compensation ? How is it possible to eliminate the errors in a synchronized fashion with respect to the surface of the shaft bearing in mind that I am acquired data at a low rotation speed in order to get the "even angle reference" and then I use it to remove the errors in the vibration signal acquired at normal operation. In this application both operations are made in different acquisitions, therefore the reference of the correction signal is lost. Is it simply compensated without synchronizing ?
Our application is based on FPGA and we need to clarity those aspects before implementing the procedure.

Rear input become low audio if both inputs are used in Inspire 4.1 4400

Hi, I am having a problem with my creative 4 in . if you test the front input without connecting the Rear input the sound is OK and vise versa, but if you use both inputs the Rear input become low sound and the front input is ok. i check my source and there is no problem in left and right audio output. i checked the cables and interchange it also the same problem. any help is highly appreciated.

The 4. creative speakers, the main lead the comes from the sub then connects into the pc, ends with two audio jacks, a green, and a black. Im sure you guys know what im on about, i don't know the proper name for this you see. Anyway s my tv doesn't have green/black audio ports like on my tv. Im guessing this is because its not a p, i also read something about the black/green being stereo inputs. Anyway s the type of connections my tv allows (audio connections) are av in (audio l/r), dvi in (audio l/r),pc in (however this only has port(audio) component in (audio l/r) etc. I have no idea if there's like adapters or anything yo can buy, if there is, if anyone can postt them, or give me a rough idea what i need to look for, buy etc. Would be much appreciated, as i like to watch my films though half decent speakers and not the crappy tv ones.

Hella,
Unfortunately, you have to buy two seperate "Y" mini stereo (that's what those green and black cable jacks are called) to Left and Right RCA jacks. You use one for the Front Audio and the other for Rear Audio.
I am no sure where you are from but you should be able to buy them from local electronics and audio store such as Radio Shack, Best Buy, Circuit City and/or Fry's Electronics if you happen to be lucky enough live near one. It should not cost more than 10 dollars a piece and you should not need it to be longer than 3 feet long.

Advenced Signal Processing 7.5 Run Time Engine in LVIEW 8.2 Installer

Hello,
I am trying ot create an installer using LVIEW 8.2 and I need to include the Advanced Signal Processing Toolkit run-time engine but this is not listed in the 'Additional installers'.
I have run and installed the Advanced Signal Processing Toolkit (7.5) and the run time engine on my machine.
How can I include this run time engine in my installer?

The Application Builder of LabVIEW cannot let you select the Advanced Signal Processing Runtime Engine like you select the LabVIEW runtime engine and other driver engines. You have to do it by yourself.
What the Advanced Signal Processing Runtime Engine installer does is to install the DLLs to the system32 folder. So what you need to do is to add the DLLs to your project and configure your installer to install the DLLs to the system32 folder.
See the attachement for more hints.

thank you for your advice...... but iam using an evaluation version from labview and even i downloaded the evaluation version from the advanced signal processing toolkit .. because the evaluation version not including this toolkit .. when i download the toolkit it appears as a winzipped file.. and i dont know how can it work with the software(as in matlab we have to set path to make the toolbox included in matlab).

Help finding examples of simple signal processing - regressions, etc

Hello All,
I was wondering if anyone has any examples of simple signal processing using the NXT (Labview 7.1 student edition with NXT plugin is what we're using).
This would be for example, reading the distance from a wall with the ultrasonic sensor to see what angle your approaching at, so you can steer based on the result.
Another example would be for passing by an object, reading the high/low point in the signal to determine the center (so you can pick it up).
I'm assuming that the only functions you can use with the NXT are the ones in the NXT subdirectory on the functions palette?
Thanks for any help you can offer.

If you have WiFi at home, all you have to do is have the iPhone look for networks, find yours listed, and tap to connect. Enter password you setup for wireless connections.
For on the road with no WiFi...Edge speeds are better than dial up (with full strength) but because it has a real browser and pulls full web pages and not mobile reduced ones, you may at times think it is slower than the BlackJack only because it is bringing down more.
As for hotel, if the hotel charges, no you cannot bypass it. When you hop on a WiFi spot that does what you described (brings you to their page no matter what you try) it is because they have it setup to do so, until you accept thier terms of service (and pay if need be) it will just keep sending you to it.
Places like Panera Bread offer free wifi, but the first time you try t browse it will show a Accept screen stating they are not responsible for hacks and what not since you are on an open network. You click the checkbox and hit the button, and then you are off and running free as a bird.
Each place is just unique but all are pretty much setup that way (accept screen first). Some hotels show a accept screen and show a price but most times the price is listed at $0.00 and is only there because they paid a 3rd party provider to setup the network and that is out of the box stuff.

2d wavelet signal processing - need some clarification

Hello:
I am using the advanced signal processing toolkit and doing some extensive wavelet processing in both 1-d and 2-d.
In 1-d, when processing waveforms, using discrete wavelet transform-based multiresolution analysis, 2 "coefficients" are produced depending on the "level" chosen. These coefficients are known as the "approximation" and the "detail." The approximation at level 1 is the summation of the approximation and detail at level 2. The approximation at level 2 is the summation of the approximation and detail at level 3. And so forth. See fig. 4-5 on p.4-6 of the Wavelet Analysis Tools user manual.
I want to consider the same analogy in the 2-d case. In the wavelet transform of 2d images at any particular level, 4 coefficients are produced. (See the manual, pgs. 4-7 and higher.) These are labeled low_low, low_high, high_low, and high_high. My interpretation of this is that low_low is the equivalent of the "approximation" and the other 3 coefficients comprise the "detail." I thought then by summing the 4 coefficients at one level (egs. level 2) would produce the approximation at the level just above it (level 1). When I test this out, it does not give the expected result.
I wonder if someone who helped produce the toolkit can clarify how one gets the "approximation" and "detail" coeffcients from the 4 produced coefficients and how they relate to the approximation at one level higher.
Thanks,
Don

Let's extend the analogy of the 1-d and 2-d cases further. First, look at the Advanced Signal Processing Express VI entitled "Multiresolution Analysis." In that VI, one can see that the time domain waveform (1-d) is transformed to its power spectrum which is broken into subbands based on the number of levels chosen. The subband closest to the origin of the power spectrum represents the "approximation" and the other subbands are associated with the "details". One can see that there is one approximation level and multiple detail levels associated with the power spectrum subbands regardless of the number of levels chosen. This express VI allows one to choose whatever combination of approximation and details to reconstruct the signal, thus providing a potentially multiple bandpass / bandstop reconstructed signal.
Fast forward to the 2-d case where I would like to do the same thing. The analog to the 1-d power spectrum would be the 2-d spatial fourier transform (see attached). I am devising a similar visualization method to draw the "subbands" on top of the fourier transform as shown by the blue lines and filled rectangles demarcating mouse-selected regions D3 and D1. However, for the 2-d case, the way I see it, there are actually 3 details associated with each level as mentioned in the above post (low_high, high_low, high_high) and 1 approximation (low_low). The questions then are:
1) how does one synthesize the 3 details (low_high, high_low, high_high) into 1 composite detail for a specific level so that the visualization method I propose for the 2-d case is consistent with that shown for the 1-d case in the Multiresolution Analysis Expresss VI? Do we just add the 3 details? When I do this, I get a great composite detail image that combines the details of rows, columns, and diagonals - but still not sure if it is the proper way to combine the 3 details.
2) how does one perform a reconstruction (inverse wavelet transform) with only the selected subbands for the 2-d case? I have attempted some reconstructions using the WA Inverse Undecimated Wavelet Transform, but the inverse transform does not appear to behave correctly without the use of all coefficients (low_low, low_high, high_low, high_high). In the 1-d case in the Express VI, one can see that only the selected subbands can be used to reconstruct the waveform.
Any help regarding these issues is greatly appreciated.
Sincerely,
Don

LabVIEW 8.5 and building executable (using fxs from Advanced Signal Processing Toolkit)

Hello out there to NI and Gavin:
For for building an executable using LabVIEW 8.5 and functions from the
Advanced Signal Processing toolkit, do we still need to manually copy the
special set of DLLs related to the toolkit use to the target installation, or are these now included
within a build file for automatic installation to the target
installation?
Thanks,
Don

Hi Don,
I imagine that any improvements made to steps required to build an executable using toolkit-specific vi's would be inherent of the toolkit itself. Meaning, I imagine the inconvenience you experienced would be eliminated with the next release of the Advanced Signal Processing Toolkit.
Cheers,
Emilie K. | Applications Engineer

Question about the Signal Processing Toolkit

I am using Measurement Studio with Visual C++ 6. Is it possible to use the
Signal Processing Toolkit in this environment or does LabWindowsCVI have to
be used? Would the toolkit supply a lib/dll that could be linked into a
VC++ project and called directly from the program?
Thanks

You can use the signal processing toolkit libraries in VC++, but the libraries do depend on CVI libraries. The easiest way to create a Visual C++ project that links to the CVI libraries would be to either a.) create the project in CVI then convert it using the Measurement Studio CVI conversion wizard, or b.) create a Visual C++ project that uses the CVI libraries with teh Measurement Studio application wizard.
For more information on the conversion wizard, see the following topic in the Measurement Studio references:

Problem with Inspire 4.1 4400

Hi?I am having Inspire 4.1 4400 speakers. My pc supports 5.1 HD audio. So I bought the Inspire 4400. The pc-to-woofer connector is 2 pin connector. When I tried to connect with that, am able to hear sounds from 2 speakers and woofer. Other 2 speakers are not working. So now am planned to buy a Creative Sound Blaster Audiy Value. Is this support Inspire 4.1 4400?My motherboard itself supports 5.1, so adding Creative Sound Blaster Audiy Value, to be problem?Or how I can use my existing pc to setup 4.1 system??

well .. on normal surround systems the sound is played only on the 2 front speakers (+ center) and sub (im talking about music and normal movies). to play on all the speakers you need a surround environment something like a dvd or a surround game ... to play music and normal avi movies on all the speakers you should use a stereo x2 which ports the sound from the front speakers to the back speakers... your card might not have that option ( you could use audio spliters and put all the speakers on exit). creative sound cards have a stereo x2 as far as i know..
