Filtering white noise

Hello, I am looking for a way to filter the white noise from an input signal sine wave
I took two inputs sine wave and white noise. I added the 2 signals and then I gave to a LMS filter. I have to get the original signal sine wave but I am getting straight line in the origin.
Please resolve this issue

I used the Filter Express VI. One of the issues that I think you are seeing is that Sine Pattern VI does not have any timing associated with it. I added some timing and ran it through the filter VI. I also created another loop that uses the Tones and Noise Waveform VI to do the same thing. You should see the noise is filtered off the signal.

WHITE NOISE FILTERING

Hi,
Please any one resend this file by converting to labview 9th version
White noise filtering and Lms attached are in labview 10th version
I am unable to open 10th version, I have the 9th version

Try posting in the Downconvert thread.
They can change the version of the VI for you.

How Do I generate a Filtered gaussian white noise

Can someone please help me on how I can generate filtered gaussian white noise in LabVIEW.

Actually in the moment you specify a sample rate for your Gaussian white noise data you apply a filter equal to F_sample/2. But anyway If you want to have 10 seconds with white noise sampled with Y Hz in sample frequency. Then you create an white noise array, with 10xY samples or elements. Then you apply your filter
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

I have some dts cd's that I want to import into itunes on a windows pc and then play back on my apple tv 3 (i think its 3, about 9 months old) to listen to through my onkyo amp via hdmi as dts, when I play back I just get white noise.

I have some dts cd's that I want to import into itunes on a windows pc and then play back on my apple tv 3 (i think its 3, about 9 months old) to listen to through my onkyo amp via hdmi as dts, when I play back I just get white noise. I have seen lots of old posts which go on about converting files but am wondering wherher at the current time with the latest versions of itunes and apple tv whether this should by now be a virtual play out of the box solution.
I have tried connecting my atv to the amp by optical cable but that didnt produce anything better and am assuming that a hdmi cable should be able to reproduce everything an optical cable does.
Is this something I should be able to achieve without having to recode the files?
Tracks are imported to itunes as apple lossless, have tried setting the atv audio settings to auto and 16 bit, neither works yet I was told some time ago by an apple rep that the atv shoud be able to handle any type of audio as it just passes it to the amp to decode. I am not stupid but not that technical when it comes to audio and bitrates etc so any explaination would be appreciated.
Thanks in advance for any help

Willy, the procdedure you describe works perfectly for AppleTV G1. In fact, I frequently play DTS music discs ripped to my iTunes library as Apple Lossless (ALAC) and synched to the ATV. What happens is that, as far as iTunes and the ATV are concerned, a conventional stereo 16/44 audio file is being played; however my reciever detects the DTS data stream, and instead of outputting static, it decodes the 5.1 channels correctly. This process parallels the way DTS discs were designed to be played back: a conventional CD player is connceted, via digital out, to a DTS-aware reciever/pre-amp and the two channels of static are recognized as 6 channels of DTS-encoded audio.
However this process will only work if the player (CD, ATV, PC, etc.) sends a "bit-perfect" 16 bit/44.1 khz data stream to the decoding device. In the case of ATV G2 and G3, as has been discussed elsewhere, the unit resmaples all audio - including 16/44 PCM (Redbook CD) - to 16/48. While this is not a big deal for conventional audio CDs, MP3s, and AAC files, it mangles the fragile DTS datastream and renders it undecodable. The resulting static that you hear is just like the static you would hear if you played a DTS CD on a non-DTS capable system.
Sadly, I'm not aware of any easy way around this. You could use a program like Foobar (and the DTS plugin) to convert your DTS CDs to 6-ch .wav or .flac file. From there you could transcode the file to AC-3 and then mux it into a video container that ATV supports. You may need add a dummy video track, for iTunes/AppleTV to be ok with the file, though I'm not sure. This may be a lot of work.
Sorry for the bad news. I wish that the iTunes/ATV ecosystem had better multi-channel audio support.

MBP 17" report, occasional white noise from right speaker

My 2.16Ghz MBP with 100GB 7200rpm drive and 1GB memory arrived a few days ago. Since then I have been installing software, running apps, and generally putting it through it's paces. I have also added a 1GB stick from Crucial. On the whole the MBP has been great, except for a few (hopefully minor) problems:
1. It gets quite warm on the left palmrest, and gets uncomfortably hot between the keyboard and the screen. This is just during casual use, web surfing, downloading updates etc. The case temperature is about the same as my old 667MHz TiBook after it had been at 100% CPU for several hours (encoding video). I dread to think how hot the MBP will get doing something demanding.
2. When closed the screen appears to be slightly bent, the gap at the two front corners is about 1mm wider than the gap at the latches.
3. I have started to get hard crashes during the boot up sequence. Specifically after the grey apple I get the greyed-out multi-language reboot message and have to reboot. If I continue trying to reboot it eventually manages to get past the grey apple and boot up normally (usually this takes 2 or 3 attempts). I suspect this is due to something I've installed, possibly some Canon software for my MP750 printer.
4. I have now heard a white noise/static sound coming from the right speaker on 5 occasions. Three of those occasions were while booting (one of them was when I first turned the MBP on! Not a good sign). The computer boots normally, but with this strange noise! The other two times where when I was launching apps. On each occasion the noise lasted about 3-5 seconds before stopping. It's more of a hissing noise, not a mooing or a whining noise. It sounds exactly like the speakers on a vinyl record player when the needle is in between songs.
Obviously all of the issue are annoying. However I'm only REALLY concerned about item 4. Item 1 was kind of expected after doing some pre-purchase research. Item 2 is annoying in a £1800 laptop, but I can reluctantly live with it. Item 3 is frustrating but I'm sure I can 'cure' it by removing software (it only started happening after a day or two of fairly heavy use). Item 4, on the other hand, is intolerable
Anyone have any suggestions? Advice appreciated. The nearest Apple store is about an hour away, so advice other than "take it to a Mac 'genius'" would be appreciated.
17" MacBook Pro 2.16GHz Mac OS X (10.4.6) 2GB RAM

Well, that was 15 minutes of life wasted typing out the above post that I'll never get back
I was hoping for some sort of 'expert' advice from all the users here with thousands of posts. Evidently not.
Anyway ... I have (kind of) fixed the problem myself. Resetting the power management unit almost completely solves the static noise problem. I say almost, because since resetting the PMU (about 2 weeks ago now) I have heard the static noise ONCE. This is compared to hearing it around 3 or 4 times a day prior to the PMU reset.
This at least makes me slightly more confident that this is a software/firmware glitch, rather than a hardware fault.
Hope this helps someone.

White noise, sort of packet loss when talking with...

Hi,
For some unknown reason when I talk with one specific person the call doesn't exactly drop out it sort of cuts the audio and gives me white noise (sort of like when you get packet loss when transferring files or gaming), I have 0 idea why it does it. Does it the reverse as well, but only for me and this person. Everyone else thats in the call doesn't get effected and its frustrating me.

When in a call goto call > Technical info. This will show you various info about the call connection (and a lot of useless info aswell). Amongst the info is packet loss, and relays (if relays = more than 0 you are not directly connected).
Being on the same Skype, version might help.

How do I get rid of the white noise that plays over my music?

Hey.
I got 5 CDs today and I wanted to upload them onto my iTunes to put on my iPod. But when I put in 4 of the CDs I got white noise over the top of the music making it unlistenable. But the 5th album(Double CD) worked perfectly fine. I know the problem isn't the CDs because I played them through my PS3 and they were absolutly fine. If anyone can help. Its greatly appreciated.
Thank you.
- DowellG8

Go to Edit > Preferences > General > Import Settings and check the box for error correction, and then try one of the problem CDs again.

White Noise showing up in images after PDF Creation

I am currently running into an issue making PDFs from InDesign CS4. Lately, our company has been getting some rather large jobs in to print and that's when this all started.
The current job is 190 pages plus cover that will be perfect bound. The client, nor I can make one large PDF from this job so we have to break it up into sections. Usually each of the PDF sections has around 20-50 pages per.
Now the issue we're running into is that on some of the pages, an image will end up with a bar or lines in it that looks like white noise. Like the image information was lost for a short period of time during the PDF creation from InDesign.
Here are two pictures of pages from separate jobs and a close up on what's going on. **Second image was from a 32 page plus cover document we have already printed.
Now in order for me to fix this issue is to just make a single page PDF of the effected pages in the document. I just wish I knew what was causing this issue so I know how to avoid it in the future. So far four jobs have been affected like this; two 32 page + cover jobs, a 64 page + cover job, and is job.
We use a Rampage Workflow system here. My PDF settings in InDesign CS4 has all compression turned off, no profiles or color conversion turned on. I keep compression turned off because it seems sometimes, vector art done in Illustrator does not seem to come out looking well when RIP'd in Rampage.
My main computer is a 2.8 GHz Intel Core 2 Duo iMac with 4 BG of memory running Mac OS X 10.5.8.
My current version of InDesign CS4 is 6.0.3. If anyone has run into this problem or if anyone has any helpful hints for me, I could really use them please. If you need more information from me, I'll be happy to answer any questions.
Thanks for all the help!

That one has come up every now and then and has always been hardware as far as I know.... bad ram, bad cable, bad drive, bad network maybe even bad video card (?).
I see that the lines in the rotated pic are parallel with that pic, so maybe look at the machine where that pic was made and placed first, this is not definite, but you can get corruption in tiffs on machines with hardware errors and they may not be visible every time you open the file.
Although probably a bigger clue is the fact that doing singles is working better, that would make me change the ram completely, suspecting a bad module. Also, unplug peripheral devices and see if that has any bearing.

"White Noise" at Start up

Whyen I power on my imac, the screen is white and then the tiny apply appears with a progress bar circling around it. Then, the screenturns into "white noise" similar to what a TV loos like when the cable isn't working. Any ideas?

no noise at all. the screen starts going crazy. sometime lots of verticle lines that are very close together and pulsating. I just restated again and this time the verticle lines pulstaed for a minute and now the screen is grey design with a yellow verticle band going up and down in the middle of the screen and a pink band on the left side of the screen.
when I hold down the option button at start up, I get a picture of the hard drive icon on the screen with an arrow pointig towards it. it looks normal. when i click the arrow, the apple appears, then the circularl progress bar...and then the screen back to freaking out.

White Noise / Popping Problems

Hi,
This question is more about microphone equipment than GB2.
I have a Sure SM58 microphone -- am going to be recording an audiobook. I need to get some sort of pop screen (to help keep the "P's" fromm sounding so puffy) ... do I need to buy a proper "pop screen" or can I just get one of those wind screens that cover the mic head (cheaper) ?
Also, my G5 makes quite a bit of noise -- I think part of it is contributing to the background "white noise" of my recordings ... I have read that a windscreen sometimes help.
Should I get both a windscreen and a pop screen? And: any other suggestions on how to reduce the "white noise" (without building a seperate room for my mics)?
Thanks,
Damon

I couldn't underscore enough how important a defuser (pop screen) is. If money is tight, a very cheap thing to try is pulling a pair of pantyhose or stockings over a coathanger.
As for the white noise, a wind screen isn't likely to help (if it did, it would be cutting off all the high frequencies of everything).
The first thing to try is to get the mic as far away from the machine as possible, keep the gain on the mic as low as you can, and stay close to the mic (again the defuser is rather important for this)
One other thing you might try is looking in your Energy Saver preferences and try setting the speed of your processor to "reduced", this may bring the fan noises down quite a bit, and once you've recorded your part you can reset the preference to Highest or Automatic)
Hope that helps --HangTime [Will Compute for Food] B-)>

September 2011 MacBookAir4,2 1.7 GHz White noise even when sound turned off

Since new this MacAir has had a white noise like a tv not tuned in even when sound is off. Gets worse as it gets warmer. Seems to be getting worse then ever.(summer). Usually connected to a Thunderbolt Display and makes noise only when display is attached. Disconnect the display and the noise goes quite after a few minutes till display is again attached.
Mountain Lion OS X 10.8.2 (12C60)
I think it is the Cooling Fans making the noise and the Thunderbolt connector gets hot after a few minutes.

Hello and Welcome to Apple Discussions.
Try checking the hard disk for errors just in case.
Open Disk Utility, in the Utilities folder in the Applications folder.
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the menu bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click Verify. Of Disk Utility reports errors, click Repair. When it's finished, from the Menu Bar, select Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.
Also, while you have Disk Utility open, Repair Disk Permissions, reboot and see if the sound anomaly still exists.

Why is the video audio white noise when I share my project since I updated to 10.0.9

On the movies I created before I updated to 10.0.9, the audio prortion of the video is now white noise. The audio is fine when played back in FCP, but when i share the project it is white noise. When I burn it to BluRay the audio is gone all together. Even when I make a master file to my desktop, it still happens. The music I added to my project is fine. It just the audio that is part of the video clips that is affected. I've turned off the EQ's and Compressors I was using and I even tried moving the audio to the center channel instead of mono. No luck. Need some help. I can't figure this out.

I'm encountering the same problem as the original poster. In my case, I'm using FCP 10.1 (running on OS 10.9.1). My source file is DV video imported via FireWire from a DV camcorder. The clip's audio is fine when playing inside of Final Cut Pro 10.1, but when I share the project the audio track is just white noise. My share settings are to Apple 720p devices (the subseqent dialog boxes indicate the software has figured out it's really 640x480 video).
Here's what the QuickTime Inspector says about the source file:
Format:
DV/DVCPRO - NTSC, 720 x 480 (640 x 480)
Linear PCM, 16-bit little-endian signed integer, 48004.6 Hz, Mono
Linear PCM, 16-bit little-endian signed integer, 48004.6 Hz, Mono
FPS: 29.97
Data Size: 5.87 GB
Data Rate: 30.30 Mbit/s
Current Size: 640-480 (actual)
I tried changing from "faster encode" to "better quality", but it made no difference.
The rather dated version of Compressor I have (v3.5.3) was able to encode the clip to H.264 640x480 and the results are fine. However, it took way longer than FCP 10.1 (I think it's too old to be taking advantage of the GPU).

New 21 inch iMac with mic white noise

Internal mic creates white noise when speaking on Face Time, Skype, or iChat. It is resolved if I plug in my iPhone headphones. I tried a PRAM reset and moving the computer location in case there was a problem with grounding, but to no avail.
Any suggestions or is it just a bad mic? I ordered the computer day 1 it was released this last month, maybe that was the problem.

Go to /Applications/Utilities and run Audio MIDI Setup. Toggle outputs and then try again.
If still no joy, tote that new bad boy into the nearest Apple Store and have them offer and opinion - if that's not an option, get on the phone to Apple...let them FT w/you and see what they think.
Good luck in any case.

HELP! My ipad screen is showing some kind of "snowy-white noise TV effect" it looks kind of "grainy". This ipad is new, no drops or accidents whatsoever... and thanks in advance!

HELP! My ipad screen is showing some kind of "snowy-white noise TV effect" it looks kind of "grainy". This happened when i was reading a pdf an zooming in for a better view, now this "snowy, grainy" screen is also showing up in the home screen...This ipad is new, about 2 weeks with no drops or accidents whatsoever... I'm thinking of replacing it... responses greatly appreciated and thanks in advance!

Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset.
but it is possible youhave a hardware defect and will need to return it.

White Noise when using ProTools

I have a PwrMac G5/2 CPU/ 2 gig Pwr PC.
I use ProTools LE 7.1.1 with an Mbox-1
When I load ProTools, I get a high pitched noise coming from the Mac, and it gets picked up in my recordings. This noise only starts when I load the ProTools App. If I close the app, the noise stops. It sounds like it's coming from the left side of the Mac, just above the power button on the front.
There has been a lot of discussion about this on the Digidesign forums, but no real explination or fix. I was just wondering if anyone on this forum has run across this and what the results were.
Ray

The noise I can hear in my speakers and headphones. I did some further experimenting last night and bounced a couple of recorded sessions in ProTools to disk. When I listen to the bounced versions, I don't hear the noise, so I surmize that the noise isn't getting into the recorded tracks. This is the first time I've bounced tracks, so up until now I've only been listening to playback from ProTools.
I also noticed that when I have my headphones plugged into the Mbox, and close ProTools, the white noise changes to a pulsed beeping sound, almost like a stopwatch. This is also a symptomatic sound reported on the Digidesign forums.
