Background noise/hiss

When attempting to record on GB , I am experiencing a lot of background noise/hiss.
I am running my guitar through a Pandora PX4 , then through a Presonus Inspire into the mac. I don't experience the background noise when going directly into the Inspire so I can only assume the problem is with the PX4. Is there some input settings or something I may have missed ?
As a point of note , I don't experience the same problem when using Cubase LE , which leads me to believe it could be the settings on GB.
I could continue with Cubase , but would prefer to sort this problem out instead as I far prefer using GB.
Thanks in advance.
ibook G4 (1.42) Mac OS X (10.4.6)

Yep , that solved the problem.
I suppose the GB effects conflicted with those on the PX4.
Thanks

N95 background noise/hiss

My new N95-1 produces quite a bit of background noise/hiss while playing music or other sounds, both on speakers as on (wired) headphones. It's not the screen-whine, and it's not solvable by disabling key tones, which I've disabled anyway.
There are more reports of this on the forum, but I'm not sure if I'll just have to deal with it, or that it's a faulty device. Either way, I'm not happy with it. I don't except superb sound quality, but being a flagship multimedia mobile it should at least be "good".
I've compared the output from the N95 to the output of my 3-year-old computer, with plain and simple Realtek AC97-audiodevice. The recording levels were unchanged between the two recordings, and I've used pure analog recording, using a wire (relevant for PC). The same 256Kb MP3 was used on both N95 as on the PC. The MP3 (a ringtone) has silence in it, for good comparision. Loudness, 3D effects, equalisers, stereo enhancers etc. on the N95 are all turned off.
The result is here (image).
Meaning of the numbers:
1: start of the recording
2: hitting 'play'. DSP starts, producing a tick. Nothing unsual.
3: the noiselevel. Notice the difference between PC and N95.
Is this a case for warranty? Or is the noise level on the N95 always this bad?
Does your N95 hiss like a snake?

Yah i noticed that also from the first day I got the phone. I guess it's 'normal' for Nokia phones. I used k750i before and it was very quiet (and not considering the sound quality was better also).

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

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.

How to reduce background noise of a conference recording..

I've made a recording on a digital camera in a conference. There's background noise, hissing and people coughing, cutlery noise etc that i'd like to minimize so that the speaker's voice comes clearer.
Anyone with good references or tips for that?
Many thanks..

if the sounds are during the speech, there is no really perfect solution. you might try using the graphic EQ to lower some of the higher frequencies (cutlery and hiss) and boost some of the lower-mid tones (where speech is). also the Gate can be used to silence low bg noise in the silent passages.

Background Noise Reduction Tips

I'm new to FCPX, having been a long time iMovie user.
I'm editing an 90 minute video of a Christmas program (which includes two 30-minute plays) shot in our church last night. All cast members with speaking parts had lapel mics; but there is a lot of competing background noise from small children and babies (some of whom were crying part of the time) in the audience (mostly the first three rows). I realize there's no magic wand that will take all that background noise out, but does anyone have any tips for reducing/minimizing it so viewers can hear the cast members better?
Thanks.

One thing is if the audio you are trying to remove sounds the same as what you are trying to keep (like trying to remove people talking in the background versus someone speaking in the foreground), then it gets more tricky.
I've had good results using SoundSoap. It's not very expensive and It works as a plug-in for FCP X - fixed an interview with it last week and the results were impressive. It will take out background noises, hiss, pops, clicks, etc.

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).

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.

Getting rid of background noise when recording cassettes

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

portercm wrote:
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:

To get a sense of what's out there, here's a selection of noise reduction apps from Sweetwater's site:

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.

How to reduce background noise using garageband?

I have a video file that contains quite a bit of background noise (just basic camera noise mostly) and I was wondering how to reduce or remove that using Garageband. I have read in other discussions that I could use the graphic equalizer, but I don't know what that is or how to use it. Does anyone have any ideas as to how I could get rid of this background noise?

I'd suggest looping a piece of silence in your sound in Garageband (using the c key to turn cycling on) and listening to just the background noise. Then open a 31-band EQ as an effect on the track and start pulling down frequencies. If it is mainly hissing and rumble, you might be able to eliminate much of it using EQ.
Another solution is to open the Visual EQ and check the analyze box, and then loop/cycle play back your track so it loops just the silence with noise. This will allow you to see in the Visual EQ window what frequencies make up your background noise. Then I'd suggest using a 31-band EQ and gently start pulling down the frequencies that are dominant in your noise. Go carefully and listen as you do it, you might be affecting they sound that you want.
To avoid making the audio you want sound thin and hollow, think about these aspects:
For male voices, most of the wanted sound is between 125 Hz and 8 KHz
For female voices: between 300 Hz and 12 KHz
So basically drag the faders on the EQ on the frequencies outside this range. I'd suggest a 45 to 60 degree slope down on the EQ, so it's not a harsh transition.
It does depend on your source audio. Is it music? Speech? I use the above as a guide You have to experiment and listen as you go. It helps to turn the EQ on and off during playback to hear the before and after your adjustments too...
This is great, oz.
But do you have a video showing how it is done ?
My source are vocal singing ...
Thanks

Removing background noise on only one of two tracks

Hello and thank you in advanced for your help. I am new to STP but well versed in FCP. I've recently discovered the wonderful feature of removing background noise in my video clips.
I'm having trouble with one instance though: I have footage shot with a microphone into only one channel of the camera. In FCP, I highlight that channel of audio and "send to" STP just as I have other clips. This time, however, no matter what I seem to try, both left and right audio channels show up in STP and I can't seem to separate them in order to remove the hiss from only one channel.
If I proceed as normal and select a portion of the hiss to set as "noise print" I can only select both tracks, not only the track I want. Probably a matter of a simple button, but I don't know STP well enough and the manual was no help. Anyway, continuing with the process to "reduce noise" and adjusting the parameters I hear almost no difference when turning the filter on and off.
I'm not sure if I've explained my scenario the best, but I'd appreciate some assistance.
Thank you!
Eric P

Eric,
Make sure the stereo file is open in the Editor as an Audio file. Click inside the editor window area and move your mouse pointer up to the top of the left channel's window border. If done correctly a tiny "L" will appear. This lets you know you can select the left channel, or portions of it.
Do the same for the right channel. However instead of moving the mouse pointer to the top area of the window, move it to the bottom of the Right channel's pane. Look for the tiny 'R."
Proceed as normal: Set a noise print, adjust parameters, and process. You'll find only the selected channel will be processed.

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.
