ONLY LOW NOTES of a sound !! please help me !
HI ALL !!
I would like to try this handling with labview:
material used:
- sound card (in & out)
- mike
my small experiment:
1 _ I put a sound beside the mike, the sound is recorded
2 _ Then restored WITHOUT the ACUTE (or shrill?!) ones, I want to keep low
notes
It seems that with the transform of Fourrier i can arrive there?
if you can make this project for me + the explanation or it
formula of Fourrier it be hyper sympathetic
I try to include it
excuse my bad english...
The following webpage contains sound card VIs:
http://zone.ni.com/devzone/explprog.nsf/6c163603265406328625682a006ed37d/b50a37358204d4078625667a005179c1?OpenDocument
You could use the Sound In VI's to record the sound. Then, you can use the digital filtering VIs (in either Full or Professional versions of LabVIEW) to filter out the high frequencies.

okay, so i bought a movie on apple tv and it says over 2 hours of waiting time! also, it said to lower the resolution so i did, but it didn't help it only made it longer... please HELP!
Sounds as though you have a slow internet connection.
Check on a computer at speedtest.net.
For near instant playback, you need:
2.5 Mbps for SD
6 Mbps for 720p HD
8 Mbps for 1080p HD
Any slower for a given quality and it has to buffer in order to playback without interruption.
The buffering could be minutes or hours depending on how much of teh movie has to buffer.

when i open iphoto i see my photo's for 1 second and then they are gone .The photo's are still there but i can see them only on the bottom or top of my screen when i try to open them i get a sign that it is not possible.Can somebody please help me?
Have you upgraded to iPhoto 9.6 for compatibility with Yosemite? If not, try that first.
It looks like iPhoto has lost the connection between the thumbnails and the original image files.
This can be caused by a corrupted iPhoto library, or the originals have been deleted or moved.
Try first to rebuild your iPhoto Library:
If you do not have a current backup of the iPhoto library, make a copy of the library, but do not overwrite any previous backup.
Launch iPhoto with the ⌥⌘-key combination (option-command) held down.
Select "rebuild" from the first aid panel. This may take a while for a large library.
Can you now see your photos again?
If not, rebuild the library with iPhoto Library manager as described by Old Toad: Re: iphoto crashed -

Since you have already done some sort of reset on your Airport Express, you might as well make sure it was a "hard reset" - follow the instructions for a hard reset found at:
http://docs.info.apple.com/article.html?artnum=108044
Since your Mac is running Leopard, you need to configure the Airport Express using the Airport Utility found in the Applictions->Utilities folder. You cannot install the old software that was supplied on the CD you got with the Airport Express.
In future - if you do something bad with network settings on your Mac, do NOT try to fix it with the Airport Utility. The Airport Utility is only used to configure the Airport Express - and since the problem you have created is on the Mac and not the Airport Express, there is no need to be using the Airport Utility and especially there is no need to be resetting the Airport Express. -
CS Bridge when opening file shows " Some Application Components are missing from Application Directory- Reinstall". Uninstalled with uninstaller, reinstalled from disc. Message continues only in Bridge not in PS. Please help.
What version of Bridge and Photoshop and what platform? Mac or Windows? I can point you to a downloadable installer.
If the cdrom was damaged, it may be the problem.
You would uninstall and use the CC/CS Cleaner to remove any remnants before reinstalling.

I'll be gone for most of the day, but someone should be able to help you if you get stuck.

I was filling a form online, then I got to where I had to upload a Microsoft document but when I clicked on upload document I only had the option of uploading photos and videos, but not Microsoft doc. Please help.... How do I upload Microsoft doc and other related office documents?
tis true
I know, I always do that but I was in a rush to get somewhere and I was relying on my thousand dollar Mac to do some kind of recovery or something. I know Microsoft always keeps temporary files (I think Mac does too, part of me asking here in this forum was for someone to tell me where I can find those files) and when you go to open Office Works then it gives you the option of opening the last recent documents, saved or not saved.
I usually copy paste into my emial just in case something goes wrong with the created document but I just didn't have the time to login and do all that My loss, you live and you learn, BUT still if ANYONE got any info on this, PLEASE DO CHIME IN *keeping the hope alive* -

Hello, the 'Save As' dialog box used to allow the backspace button to go up one level in the directory when the focus is in the folder contents box but it does not work any more, please help. BTW the same 'Save As' dialog in other applications still allow the backspace button to go up one level in the directory.
cor-el,
I kept forgetting and procrastinating about following your instructions, since I have internet access only for limited amounts of time and usually I am busy with important tasks when I am.
Out of the blue, the problem corrected itself (the Save As box started to open full screen, then shrunk down to a normal size and the edges can now be dragged to a custom size).
Even the copy and paste problem in the filenaming area seems to have been less troublesome lately even though there have been no updates to Firefox in a few weeks.
Even though I marked the solution as not helpful, the problem has in fact been resolved. I will save the solution instructions in case the issue returns. -

U are using where condition in a Loop ,while executing last record may or may not get executed becoz of restiction.Better declare a variable and SUM under such scenarios.

on apple tv you can sign in to mobileme account but it wont allow me to, it says mobileme account could not be found. please help??
OK - I am trying to be rude either, just very frustrated.
I hope the OP is not put off and for her benefit I will post this.
If you are looking for galleries and have an otherwise functioning ATV2 read no further.
If you are trying to get your unit to work because:
1) You have selected to send feedback to Apple and then wanted to key in your mobile me address and failed, or
2) Tried to set the iTunes store by using your me address, because they are the same, or
3) You are trying to set up home sharing using your mobile me address
then as part of the set up process you will, having keyed in your .me address and password, have got the message that your mobile me account can not be found.
If you look under the general section, you have the option to set time zone. If this shows Cupertino and you have selected either "automatic time setting" or keyed in another town not on Pacific ST and you are not in Cupertino then date and time have not set.
You can unplug the unit and leave for a few minutes, you can select to reset and restore. You can check that your router allows access to the necessary ports (typically 53, 80, 123, 443, 3689 and UDP 5353).
If your Apple TV on reset and opening the ports, still hangs at "setting date and time," then you are one of a group of people being blocked access for some reason that is not being shared openly - other than my comment above about server issues at Apple's end. This is not malicious but just repeating information posted on this and other fora. I can not confirm or deny, but when every other option has been discounted then only certain solutions remain.
I wish you luck in getting your ATV to work as it should.
PS I don't think cables are an issue here as you obviously are seeing something on the screen to see that you can't log in.
Maybe you are looking for
