To stop background noise-cassettes to G.B.to ITunes???

Moving old cassettes tapes into GarageBand --getting a lot of interference on some of them--can this be fixed in G.B. or do I need to download another extra program.
PowerMac12,1 Mac OS X (10.4.9) Also have a MacBook

If you are doing a lot of this consider the excellent BIAS SoundSoap 2. It can be used as a au plugin from within Garageband or as a stand alone app.
I have been very happy with this program. I have found that tape hiss and hum are its specialty, and it has o.k click removal. Check out the video:
BIAS Video Tours: SoundSoap 2
Pros:
Excellent hiss and hum removal.
Works as a plugin in Garageband.
Simple interface and excellent automatic feature. Noise removal can be manually fine tuned as well using the knobs.
Cons:
Garageband plugin seems to only work on one track at a time.
Click removal doesn't work as well as I would like.
Standalone program is slow at rendering the file.
A little expensive: $129
The free Audacity has a noise removal tool as well.

Getting rid of background noise when recording cassettes

How do I get rid of the hissing background noise when I transfer cassettes into GB?

Thanks - this is totally new to me. What sort of software do I need to clean up the noise after the fact? I'm dealing with old cassettes and a cassette player with no dolby option.
there's a bunch of applications that will clean up or "restore" noisy audio, and they range a lot in price and features. Here's a few options:
Bias makes Soundsoap 2 (around $100) and Soundsoap Pro (around $550). Bias makes some great audio software, so Soundsoap 2 might be more than adequate.

If you think you might want to use Roxio's Toast 10 Titanium Pro (around $115), it comes with a version of Soundsoap included. As long as you don't need the features of a dedicated noise removal application, it's a pretty good deal:

IPod Shuffle 4th generation background noise

Apple appear to have archived the original discussion about background noise.
I find the noise to be prominent.
Through the (presumably low end) headphones that came with the iPod, I can't hear that much hiss, nor any whine - just as with my old 2nd Generation Shuffle.
But I still play the Shuffle in my car. I use a tape adaptor. With my 2nd Generation Shuffle, there was never any noise problem. However, the same songs - and, especially, the podcasts - played over my 4th Gen Shuffle, through the same tape adaptor, now have a loud background noise.
Many people have described this noise as a "hiss." For me, it is not simply the white noise that you might get from an old cassette recording. I am in agreement with the user who said: "Honestly this sounds more like Tinnitus than any fault on the end of the buds."
In my case, in addition to the white noise, there is a high-pitched singing from the moment you turn on the iPod - akin to the sound given off by a dog whistle, or the traditional cathode ray tube television set when it's turned on. The traditional TV whine was never that audible to many older people, people with damaged hearing, etc. But, to those with good high-end hearing, it can be noticeable - and quite annoying.
Check out this page: http://journal.plasticmind.com/ears/mosquito-tone-or-how-to-tell-youre-a-youngun /
Applying the above test, I would say that my iPod delivers a steady squeak/whistle at around 15Khz.
Additionally, when I hold the forward and backward buttons to move quickly through tracks, there is a high click akin to the sound made when you start or stop any of the test tracks from playing.
I find that the background squeak is, for some reason, less of a problem with music tracks than with podcasts.
If I turn on the Dolby noise reduction button on my car's tape-player, I can actually eliminate much of the noise. However, then the tracks are significantly muffled. I never liked using Dolby at the best of times but - since iTunes tracks were obviously not prepared in Dolby - there is a distinct fall in clarity (especially in the podcasts which contain speech) when Dolby is switched on.
The way things stand, I'm inclined to take my 4th Generation Shuffle back, and replace it with a less irritating 2nd Generation Shuffle.
Anyone else experienced this?
Do I just have a duff iPod? Should I just try replacing it with another 4th Generation model?

I am in exactly the same situation as you - I got my 4th gen Shuffle yesterday (after my 2nd gen was accidently put in the laundry). The 2nd gen version was brilliant so I assumed the 4th gen would improve it even more, however the first time I plugged it into the cassette adapter in the car, I assumed it was defective. The background whistling and clicking between tracks ruins spoken word or quieter songs. It means its not really useable with a cassette adapter, which is a big let down, as thats the purpose I bought it for! I am going to see if I can send it back and get a 2nd gen from somewhere. I know cassette adapters are old tech, but its frustrating that a newer version of the Shuffle has this big issue with them, whereas an older model does not.

Headphone Background Noise/Hiss

When listening to music through headphone on my Inc, there is some slight background noise similar to the faint hiss/hum you get when listening to an old cassette. Its nothing that loud...you can only hear it during quiet parts or silence. It is there even if the volume is zero. When I pause or stop a song, the noise remains for a couple seconds, then goes away.
Is this normal for Droid's or do I have a defective chip/jack? All other mp3 players I've ever owned have had crystal clear audio (silence is dead silent) and I'm trying to get rip of my ipod and only use my Droid, but if this is normal its a deal breaker.
Thanks

I have provided some information below that may help.
1.      Try using another pair of headphones.
2.      Try clearing the cache and data on the music app. Instructions are listed below:
-Select Menu
-Select Settings
-Select Applications
-Select All
-Select Music
-Clear Cache
-Clear Data
3.      Try a soft reset. Instructions are listed below:
-Power the device off
-Pull the battery for 20 seconds
-Place the battery back in
-Power the device back on

How do I eliminate background noise from a recording?

I loaded an audiotape from a cassette to my MacBook. There is too much background noise and I don't know how to get rid of it. Is it possible? Thanks, Miriam

One option is to use the (free) Audacity. Just load the mp3 or aiff and follow the instructions to construct a noise profile and then get rid of the background noise. Once that is done, one can reimport the file into iMovie, if you choose.
Export the file from iMovie 09 as mp3 or aiff file. Import into Audacity. Get rid of the noise. Export from Audacity as a mp3 or aiff file, and use that as you like.
To find out how to use Audacity, I recommend checking out the fine tutorials on YouTube.

Background noise reduction

I would like to find a way to reduce the amount of background noise/hissing from my file.
I have been importing audio (music) from a cassette tape directly into Soundtrack. After making the necessary edits to the track I have been using the "Bitcrusher" effect to improve the "punchiness" of the sound. Then I have been exporting to iTunes as an .aiff file, followed by an import for iTunes and the file is transferred into my music file. Then I burned to a CD.
The sound is just okay and there is definitely a loud hissing noise as the volume is turned up. Does anyone have suggestions on how to:
a. Improve the overall quality of the sound?
b. Reduce the mount of background hissing/noise
The noise is not very apparent during playback on my computer just when I play it back on CD.
Thanks!

Bob,
Soundtrack Pro (STP) is currently at 1.0.3.
Where you have a section of your audio with no voice but background noise, did you use that as your noiseprint (STP, menu bar: process then set noiseprint) or as the section for Bias Soap to learn? After that, use the tool settings to listen to what either program is actually taking out (STP, menu bar: process then reduce noise, or Soap, and click noise only in either one). I typically reduce the amount of noise reduction to ensure I'm not affecting the voice (you don't want to hear the voice in noise only mode). Then I listen to it normally to ensure I haven't over done it on the noise reduction.

DVR620KU Makes Background Noise When Dubbing

Hi, I recently purchased a DVR620KU. I started dubbing VHS tapes to DVD+R. The VHS tapes sound good when I play them alone, but as soon as I begin dubbing to DVD I can hear background noise, like a persistent light tapping sound. Thus the DVDs end up with this background noise that isn't present in the original tapes. I tried different DVD speeds. I also removed the machine completely, plugged it into a different wall socket, and tried dubbing without the unit connected to any other devices. The noise was still present when I played back the new DVD. The noise is not present in DVDs that were not dubbed by this machine. At this point I am convinced that the Toshiba DVR620KU is the root cause of the background noise. Do you know what Toshiba's explanation is, and what is the recommended solution? Thanks.

The noise is initiating from the VHS playback, and then being written into the DVDs. The noise only occurs when the DVD is either dubbing or recording the L1 circuit (even when the L1 circuit is empty, the VCR playback is still affected while L1 is being recorded to DVD). When the DVD player is off, the noise is not present in the VCR playback. I'm not sure how to determine whether the noise is originating mechanically or eletronically. But it ends up as part of the sound transmission through the speakers. I'm not hearing something banging inside the machine, if that's what you mean. If you tapped on a microphone repeatedly while it was recording, this is what the output would sound like.
So far I've identified 7 VHS tapes that are affected by this problem, and 8 VHS tapes that resulted in excellent DVDs. I just burned a perfect DVD this morning. All the tapes are T-120 cassettes that were originally purchased as blanks. Several different brands and grades are represented. All of the "bad" tapes weigh more than 240 grams (average 257g), and all of the "good" tapes weigh less than 230 grams (average 204g). I know that blank T-120 cassettes generally become lighter over time, which means the "heavy" cassettes are probably generally older than the "light" cassettes. This also implies that the material was generally recorded with older VHS players on the "heavy" cassettes. The transition between the "heavy" and "light" tapes was probably around early-90's based upon the material on the tapes and when I think the data was originally recorded. So I don't know whether or not the weight actually means anything, although it could because mass can obviously impact mechanical vibrations. But the difference could also be that different tracking technologies were involved with the older, or heavier, cassettes and/or the machines they were involved with at the time the material was recorded.
I read on a different forum that VHS cassette tracking imperfections may be present all along, but they don't become audible until the digitization process amplifies some of frequencies involving the imperfections. I don't know much about that, but to me, it's plausible that the frequency processing and flow path out of the machine changes when the DVD player is recording. I'm not sure about that either, but something is definitely happening when the DVD recorder is on that affects the VCR playback on these heavier, older cassettes.
So, at this point, I can carry on knowing which tapes will be useful, and which will be problematic with this Toshiba dubbing process. The problem is what to do about it. Perhaps if I purchased another unit and ran the VHS output from the "slave" unit to the L1 circuit on the Toshiba, the problem might be fixed. Or, maybe this unit is defective, and if I exchanged it for a new Toshiba, the problem will be fixed. Or, maybe the Toshiba design includes this sensitivity, and the only solution may be to return it for cash refund and purchase a competetive product. Or, maybe the digitization process is what it is, and these old tapes are what they are, and there is no solution.
You said you have a DVR620KU and you've never experienced this problem. I don't suppose you have any old VHS T-120 cassettes that weigh ~250-260 grams? If you do, I would be curious to know whether you have the same issue. Thanks.

DAQ background noise

Hi folks,
I'm using Daq USB-6211. Platform is MAC OS X. Labview version: 8.5.
The Daq sample at 250 HZ and each time take 250,000 data. So basically it sample 1 sec and continue sampling without stop. It's in differential mode.
The measurement starts with measuring the background noise of an ordinary coil. The coil is made up of thin copper wire with resistance 40 khm and inductance 0.1 Henry. There is a SR-560 preamplifier in between the Daq and the coil. Gain is 1000. it's in low noise mode and no filter is applied.
Now the energy spectrum shows there are 10K, 20K, 30K, 40K and 50K noise in it. They are very regular and I suspect they are produced by the Daq itself. It seems like its intrinsic clock? I really need to get rid of these noise to proceed.
Thanks,
John

John,
First, some questions about things in your original post which did not make sense to me.
1. You said you are sampling at 250 Hz and reading 250000 samples in one second. So I presume you meant that you are sampling at 250 kHz.
2. Is the resistance of your coil 40 ohms or 40000 ohms?
How do you prevent any magnetic coupling to the coil during your background measurements?
Can you post the spectral data or at least an image? What does the signal look like in the time domain?
It should be easy to isolate any internal noise from the DAQ. Terminate the inputs with a metal film resistor with a value equal to the coil resistance. Shield the resistors if the environment is noisy. Measure the spectrum.

X-Fi Titanium Background Noise

Hello all,
I recently reinstall windows and after installing the creative driver for my X-Fi Titanium there is is the background noise only when there is no audio output. This is occuring SPDIF out. It stops before a system sound is about to play and then starts right back up after it is played. If i open winamp and play a song and pause it the noise is not there. However if i close winamp the sound comes back. I tried the latest driver on the creative site and i also tried a ealier driver that came with the card. I am running Windows Vista x64. All help and advice accepted.

Sorry for the late reply but my final fix was to completely discard the creative dri've and use the default windows HD driver which works better that the creative one in my [email protected]

How can I eliminate the background noise on ishuffle?, How can I eliminate the background noise on ishuffle?

I recently bought a second hand ishuffle. I downloaded the music stored in my laptop on to my ishuffle.

That makes me sad. thannk you

Found Audacity for my background noise. Can I edit my audio files in the FCPX event folder in Finder?

I think I found the solution to my background noise problem using Audacity.
But can I edit my audio files that are in FCPX Event folder in Finder? Or do I actually have to edit my project all over again to put in new audio (edited by Audacity)?

No, copying the whole Project and Event is just too much of a waste of time.
Do this, in the Browser, select the audio file you need to take to Audacity. Export it as a Master File, and in the Settings section of the Share window, set Format to Audio Only. Set Audio File Format to AIFF. Set Open With to "Other" and select Audacity. Then pick your Desktop as the location to save the file.
In Audacity, do whatever it is you want and save it.
Back in FCP X, import the new "fixed" file, be sure to check the box to copy it to your Event folder.
Finally, if necessary, do a Replace edit with the new version to the old one if it has already be edited into a Timeline.

How do I eliminate the delay in reducing background noise with each new clip?

My microphones pick up a fair amount of background nosie. At 60% reduction with iMovie's built in editor it sounds perfect. The only problem is that it takes about .5 seconds to go from zero reduction to 60%. If this were only at the start of the new movie, that would be fine. But this occurs at every new clip. I'm editing together a long series of short, ten second clips...so there is a distracting hissing of background noise once every ten seconds. Any help on this would be great.

You may have installed a persona.
You can uninstall your current Persona and revert to the Default theme (Firefox (Tools) > Add-ons > Themes).

Filtering background noise using two microphones

Hi,
I am new to Labview so please bear with me. I am trying to work out the sound vibration level emitted from a compressor. I have a microphone placed next to it but it is operating in a noisy laboratory and therefore I need to filter out the background noise.
I have another microphone to record the background noise. I think I might need to use an adaptive noise cancellation filter but cannot figure out how to make one on Labview. I have tried simply inputting the two signals and subtracting them but get an error saying "Resource requested by this task has already been reserved by a different task" when trying to run it.
Basically I am looking for the simplest way to get rid of the background noise in real time or in processing the signals afterwards.
Any help would be greatly appreciated. Please ask if you need more information.
Thanks a lot,
Sam

An ax (also spelled axe) is a tool for chopping down trees. I was trying to make a joke. Like some other experienced LabVIEW programmers, I do not like the Dynamic Data Type because it hides the structure of the data contained within it.
The subtraction technique is standard and simple. The biggest issue is phase shift. Suppose the two microphones are 1 meter apart. A sound arriving on the line through the microphones will arrive 3 milliseconds later at one than at the other. Sound arriving along a line at right angles to the line through the microphones and equidistant from both will arrive at the same time at each. At other angles the time will vary between those values. Compensating for that delay or phase shift is necessary to get good cancellation.
In addition the amplitude of the signals at each microphone will vary inversely as the square of the distance between the source and the microphone. For sources much closer to one microphone the amplitude difference can be significant.
Directional microphones will further complicate the amplitude variations. I think that two microphones are not enough to provide unambiguous determination of the direction of an unknown source, especially when there are multiple sources.

No "Background Noise Suppression" option ?

When using a headset mic, I?broadcast a? constant background 'hum/hiss' while gaming; using Skype; or even just recording my voice with windows voice recorder... This occurs when I am speaking and also (especially annoying) when not speaking.
Most onboard audio has an option to "suppress background noise" so that at the very least, the microphone will only pick up sound (or begin recording) upon detection of your voice, thus eliminating any constant whirring/humming/hissing sound in the background.
This becomes particularly annoying to fellow gamers (all of whom have expressed their desire that I turn ON "background noise suppression).
Of course, no such option exists in the creative control panel.
Why is there no option for this? Have I missed it's? Or could this be the result of some other problem?
My card is "PCI Express X-Fi Titanium Fatalty Champion Series."
I'm running a quad-core Xeon 5335- 2.33ghz, with 8 Gbs of ram.
Vista Ultimate 64-bit.
I have tried 3 different headsets/mics and get the same problem.
?Thanks for your help,...

Thanks for the suggestion... I am aware of this option and while it does?eliminate the background hum over my headphones, it doesn't get rid of the problem for people on the receiving end of my mic.
I just find it really odd that simple onboard audio has a background noise filter, but a soundcard that's over a hundred dollars doesn't.
When gaming with friends online, I never hear any hissing or constant hum from their mics unless they neglect to activate the "background noise suppresion" in their [onboard] audio options. Their onboard audio only activates the mic upon?detection of their voice and?even then there isn't any background hum.
I have searched the net and found a couple other posts regarding this same issue with Creative Soundblaster cards...
I honestly wouldn't have bothered buying this card if I knew it wouldn't have something as basic as a background filter option.
It's an available option?with most?[what should be far less superior] onboard audio.
