Want to measure sound and display in graph

Hi guys,
I wish to measure sound that different equipments make and at the frequencies they make the sound. I am using a micro-phone connected to A/D board. I think the harware i m using is correct. But can someone tell m which vi shall i use to make my program work ?

Yes;
Go back to the examples and look up signal analysis or FFT. There will be examples showing spectral analysis, combine that functionality with the DAQ you have now and you're done.

Hello All, I want to measure sound level and do octave analysis for Pumps pl suggest a good quality microphone

Hi all, please help me to choose microphone to measure sound level of pumps

I agree with DOS. a 2.8Ghz CPU should OC to 3Ghz easy and should reach 3.2Ghz without much trouble. If I where you I would go with Kingston, Corsair or Geil, probably in that order. If you don't plan on overclocking passed 3Ghz their is no reason to go above 3200 for the RAMM frequency.

X120e Sound and Display question...

Hey, I'm enjoying my x120e that I purchased earlier this year. I still love my T61 I purchased in 2008.
Couple of things though: the sound and screen.
Sound - does anyone else have hiccups with the sound where it makes a sort of long buzz through any playback for a time? If not, I need to mail in for servicing (unless I need to do a clean install or it's something I can fix).
The display is garish, and ultrabright. Has anyone had success with switching the panel to something else?
Thanks,
Erin

If the buzzing sound only happens after resuming from sleep, there was a bios update for it long time ago. Make sure you update to the latest BIOS.
As for the screen, yeah it's pretty bad for the viewing angles, there are several panels that are being used but I dont think you could request one specific part # to be replaced. I think It was a Samsung panel that was reported to be better than the LG. I had one with LG, and it was pretty crappy if not looking straight at it.

W540 - Sound and Display in Linux

Hey dear supporter/user/reader!
After calming down due to the vast loss in quality of the new Lenovo ThinkPads (2.2k€ for such a plastic toy - rly?) I started installing a Debian sid with XFCE d/e. There were a couple of problems to solve, especially this rattly one-click-fits-all clickpad needed a lot of caring and compiling. And not to forget the first two days of my odyssey trying to boot up the machine with my OCZ Vertex 2 SSD installed with any format, partition table protocol or whatever firmware loaded - which was a sobering and vain experience. I ended up taking another SSD from my studio desktop which isn't only half the size but slower, too. 2.2k€ for a machine unable to boot a regular SSD - rly? Whatever, posting my whole snaggling-list would go far beyond the scope of this thread and we all know how capitalism and "consulting" works - so let's look forward.
There are lots of problems left but some of the major ones are:
Bad sound in Linux
Bad color reproduction from the 3k display in Linux
Sound:
In Windows the sound is quite nice. I know that it's a problem of alsa/pulseaudio drivers and that the community has to create appropriate drivers first. But there's no information around by now about the capabilities of the installed sound chip to create some usable workarounds:
Is there a subwoofer built in?
Or other channels/speakers I can route some signals to?
How is this full, brilliant and wide sound achieved in Windows?
Because just using the stereo speakers at the front edge of the notebook sounds really crappy. Routing the signal through an equalizer gets back some of the highs and the "bass" and eliminates some of the bugging mids around 1.5k but it is still far from the sound experience in Windows. And it brings in some problems because I have to setup a dirty workaround via DBus to select different presets in the e/q depending on the selected output device (speakers or headphone jack) which introduces more and more problems with muted channels after plugging a headphone aso.
Display:
The colors look quite okay in Windows, in Linux it's a yellowish-green mess. Since I read about the pretty poor quality of the built-in colorimeter before I ordered this device I didn't buy it in anticipation of the tutorials about using the Windows color profiles in Linux. Unfortunatley copying the profiles from the Windows HDD (C:\WINDOWS\System32\spool\drivers\color) and loading any of them via xicc, xcalib or any other tool handling color profiles does nothing to the color reproduction of the display. I found a profile made by a helpful person somewhere on the internet (notebookcheck? Unfortunately I don't remember) which makes this display kind of usable but it's far from being correct since it introduces a greenish inking at the lower end and a rose red one in the middle of the spectrum. Additionally the overall gamma curve doesn't fit that well. But at least it draws white as white and eliminates the overall lime style of the device.
Résumé:
Maybe I'm just an idiot, too dumb to correctly copy and apply color profiles or to use alsa/pulseaudio the correct way. If so I would be very happy about anyone who would lead me in the right direction. Perhaps someone stumbled over the same problems and has some fixes or at least ideas where to look at. Perhaps someone calibrated his 3k display with a professional colorimeter and is willing to share the results.
If someone is interested in e.g. my Xorg config, the amd64 DEB package for getting a usable clickpad, the slightly working color profile or other informations I'm able to share, please let me know.
Disclaimer:
I can understand if anyone is deterred by this rant in a way that she or he avoids to talk to such a poor goof, but perhaps someone understands my vast disappointment after spending a huge amount of money and a lot of time for a brand which is (was?) well known under (Linux-) enthusiasts for the outstanding build quality, the overwhelming compatibility and the ubergood hardware which was built into ThinkPad machines in the past. I owned, sold, recommended and installed lots of these notebooks before, my own last two machines were two t61p which I would call the peak in quality of this brand. But those times definetly seem to be over.
Thankful for every hint to make this thing more usable, best, Markus.

Here's another profile I stumbled upon. It was made for the T540p shipped with the same display. It is a little more even, so less different colours in the overall grayscale and it has a better gamma curve. But it has an overall greenish touch just like the display without any profile but considerably less.
http://mein-neues-blog.de/files/t540p.icm
And to prevent users from searching I upped the profile from my last post to my blog, too:
http://mein-neues-blog.de/files/LEN40B5.icm
BTW I'm actually hacking a GTK application for manipulating the ramps of a LUT profile in realtime since those profiles are not that bad but need a little tweaking to fit my own display.

Why does iMessage continue to make sounds and display banners on my Macbook Pro (Retina) even though I have removed it from my notification center?

I hate that my messages pop up while I'm watching Netflix, and I have finally removed Messages from my notification center. Yet, for some reason i still keep hearing the noise that lets me know I have a message, and I a still seeing badges pop up on my screen every time a new message comes in? What's the deal?

I talked to Apple Support and we at least stopped the bleeding, a little bit. These are the troubleshooting steps I did before I contacted Apple Support:
1. Reinstalled OSX
2. Restore the last known good Time Machine Backup.
This did not fix my issue, so I called Apple Support and they told me this:
1. Turn Power off.
2. Wait 15 seconds.
3. Plug in Magsafe adapter.
4. Wait 15 seconds.
5. Hold down the Shift+Option+Power Button for 20-30 seconds.
6. Turn Power back on.
Ok, this stopped the bleeding a little, but as soon as I plugged in a Apple USB Superdrive
and a Apple Mini Displayport to VGA Adapter. This "USB Devices Disabled" pop-up pops up like every 30 minutes now. At least, it is not constantly popping up after I close it, so I guess it will do for the temporary. Going to contact Apple support, later, though to see what else can be done.

When I click on a .pdf link, I want to download it and display it in Foxit. How can I do that?

I used to be able to click on a .pdf link and the .pdf file would open in Foxit Reader and be saved to my download folder.
Now, I think since refreshing Firefox, clicking a .pdf link opens the .pdf in the Firefox browser.
How can I get .pdf links to open the .pdf in Foxit Reader, and not open in the Firefox browser??

Hello ririri, you have to set it correct in the [https://support.mozilla.org/en-US/kb/applications-panel-set-how-firefox-handles-files application panel].

thank you

HT1320 If an ipod is disconnected from the USB cord without being ejected first how do you fix this matter? It's making a weird sound and displaying the Apple support email address only.

What to you do it your ipod is disconnected from the USB cord without being ejected first?

3) If this is a counterfeit, is there someone in Apple that I should contact to help them track this kind of problem?

I'm sorry, but from your description I have no idea what you are trying to do. Ok, I see that LV is doing something, and that you want to acquire sound and images, and that the web is apparently involved. But,
How is Excel involved?
What is the web interface doing?
Where are the buttons you talk about pressing located?
What are the sound and video sources?
What version of LV are you using?
What is the network you are using?

Can you tell me how to display a custom graph for a column in a alv report.
That is adding a seperate button in the report and display a graph for a column when the button is clicked.
If 'Graph_2d' function module is used can anybody tell how to pass values to the function module and display the graph using the function module.
Thanks & regards

Capture - Transcode and display

Hi ...
I'm trying to do this simple sequence of operations
Capture video from a webcam
Transcode this video to H.263
and then display the transcoded video
I want to do this without saving (exporting) to a file, I want to capture, transcode and display in real time. Is that even possible ??
I can capture and display without transcoding.
I tried to set the format of the video tracks using a processor and get the DataOutput and fed it to player object, but the player does not display anything.
Please help
Thanks

How to add a scroll bar within a view window ?I want to display x and y axis outside the scoll window and keep those axis static and move the graph within scroll area

how to add a scroll bar within a view window ?I want to display x and y axis outside the scoll window and keep those axis static and move the graph within scroll area
ananya

Hey Ananya,
I believe what you want to do is possible, but it will not be
easy. If you want to add a scroll bar that will scroll the graph
back and forth but keep the axis set, you would want to add a
horizontal or vertical scrollbar. Then you would create an event
handler for the scroll event. You would have to manually plot
different data within this scroll event. Unfortunately, there is
not really a built in way to do this with the Measurement Studio plot
control.

Read numbers from a .txt file and display them in a graph

How can I get Labview 7 to read from a txt. file containing a lot of
coloumns with different datas? There`s only two of the coloumns that are
interesting to me, the first, that contains the time of the measuring, and
one in the middle, that contains the measured temperatures. I want Labview
to read this datas and display them graphicly.
Thanks from Stale

Here's one way.

How can i cannect the output of my mathscript in the Spectral Measurements VI SIgnal Input. I'm having a problem since the output of the mathscript file "D" is DBL 2D. I dont know how to convert this data type in order to be connected to the signal input of the Spectral Measurements VI. I also want that the waveform graph connected to output of the Spectral Measurements VI, will display the FFT of the three sine waves in one graph.

My performance is very slow when I run graphs. How do I increase the speed at which I can do other things while the data is being updated and displayed on the graphs?

I am doing an an aquisition and displaying the data on graphs. When I run the program it is slow. I think because I have the number of scans to read associated with my scan rate. It takes the number of seconds I want to display on the chart times the scan rate and feeds that into the number of samples to read at a time from the AI read. The problem is that it stalls until the data points are aquired and displayed so I cannot click or change values on the front panel until the updates occur on the graph. What can I do to be able to help this?

It may also be your graphics card. LabVIEW can max the CPU and you
screen may not be refreshing very fast.
