Bought AKG 120 USB microphone - Picks up to much background noise

How can I reduce the hum? I bought the AKG 120 USB microphone for voiceover. I used a Seinnheiser ew100 G3 before - which worked okay. But I guess a condenser microphone is even more powerful and picks up more of what I did not want. When I compare the recordings the Seinnheiser is deeper and the AKG 120 picks up more hum and background noise.
Is there a software that can help me adjust the AKG 120? Right now it is picking up to much noise.

Hi Lillian83,
Final Cut Pro X has the ability to analyze audio for hum during import and while editing.
The relevant sections of the manual below will show you how:
http://manuals.info.apple.com/en_US/final_cut_pro_x_user_guide.pdf
Page 46 - Analyze Your Media
Audio analysis options
Final Cut Pro provides automatic analysis options that can fix common audio problems, analyze and group audio channels, and remove silent channels. You can analyze audio during import, or analyze video clips with audio issues in the Event Browser or in the Timeline.
Analyze and fix audio problems: Analyzes the audio for hum, noise, and loudness. Final Cut Pro automatically fixes problems that are considered severe (marked in red) and flags problems that are considered moderate (marked in yellow). For more information, see Enhance audio on page 199.
Page 199 - 201  Audio Tools and Techniques
To show the Audio Enhancements inspector, do one of the following:
• Choose Window > Go To > Audio Enhancements (or press Command-8).
• Choose Show Audio Enhancements from the Enhancements pop-up menu in the toolbar.
• In the Audio inspector, click the Audio Enhancements Inspector button next to Audio
Analysis in the Audio Enhancements section. (After you make any adjustments, the button
changes color.)
To turn on an enhancement, click its icon or select its checkbox (when the enhancement is turned on, its checkbox is blue).

  • Microphone on the ear buds picks up all the background noise.  IPhone 5

    microphone on the ear buds picks up all the background noise. 
    anyway to fix this problem

    Every time I try to talk to my wife when using the Iphone 5 with Earpods, or any other headset for that matter, she complains that the mic on my phone headset is picking up EVERY SINGLE SOUND and amplifying it so loud that she can hardly hear my voice over all the background noise.... I have replecated this problem now 10 different iphone5 of my friends.... which is every single iphone 5. Without fail they all have this same issue. It is not my wifes phone either. People always complain when I am using my headset. ESPECIALLY when I am trying to comply with new laws requireing hands free phone usage. It is unacceptable for Apple to have failed in fixing this problem. I have spoken with several customer service reps/Genius's about this and there is no fix to date. I have upgraded my iphone5 to all latest versions of iOS with the hopes that Apple will one day fix this problem with a software update. Will someone please help us!!!!! I doubt my Apple loyalty will last without a fix to this massive inconvienence.  

  • Using USB microphone with iBook

    I have an iBook G4 and GarageBand 1.1. I recently bought a MicFlex USB microphone, but I can't make it record. I have set the system preferences and I can set the record level for the USB mic there, but GarageBand automatically uses the built-in microphone for recording. How do I change this?

    No worries, now you're a little less new. Enjoy --Hang

  • USB Microphone cut's out

    This is the second USB microphone I bought (a Blue USB Microphone) to go with my iMage USB camera.
    Everthing works great except for when the sound on the mic stops working, having to unplug and re plug in the USB connection to have the mic start working again.
    Seems to be software related since this happened on 2 different mics, anyone else have any trouble like this?
    Thanks, JohnnyB

    Hi johnnywashere,
    DOes the Mic show up in System Preferences > Sound > Input tab ?
    Is the volume set high enough (to get a response at least 1/2 way with iChat ?
    In iChat > Preferences > Video section > Microphone Drop down is the same Mic selected ?
    In iChat > Video menu (may read Audio) does the Microphone Enabled item have a Tick ?
    In iChat > View Menu is Show Audio Status ticked ?
    (err..... Is it turned on. Mine has an On/Off switch)

  • Blue Yeti USB microphone not working in ALSA/PulseAudio

    Hi all,
    I recently bought a Blue Yeti USB microphone. It is supposed to require no drivers for Windows and OS X, and so far, it works well under Windows, but I cannot seem to get it to function on Arch Linux.  As fair warning, although I am relatively experienced with Linux, I don't know much about the internals of ALSA/PA --- up until now, it has just "always worked", so this is my first real foray into the area. I've tried for many days, with no success, to get this thing working.
    So, let's start off first with my configuration.
    I have a few audio devices:
    An on-board audio solution that I don't typically use. For testing, I have connected an old, crappy pair of headphones, but normally I keep this disabled. It has one capture device. (Analog stereo [or 5.1/7.1/etc]  duplex)
    An external DAC that is connected via USB and is output-only. So, no capture devices on that. (Digital/IEC958 output)
    The Blue Yeti itself, which is connected via USB and supports output (it has an internal DAC) as well as input. So, one capture device here. (Digital stereo output and analog stereo input???)
    The HDMI-out stuff for nvidia, which I never use
    Here is the output of "arecord -l":

    If the output of "aplay -L" is needed, let me know, but it's not all that different from arecord -L.
    Here is my /etc/asound.conf:
    defaults.pcm.rate_converter "samplerate_best"
    pcm.!default {
    type pulse
    fallback "sysdefault"
    hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
    ctl.!default {
    type pulse
    fallback "sysdefault"
    # vim:set ft=alsaconf:
    I don't remember where the bulk of that came from; maybe it was installed like that or maybe I put it in there. Here is another useful command showing non-commented-out/non-blank lines in the pulseaudio conf:
    $ egrep -v '^;|^#|^$' /etc/pulse/*.conf
    /etc/pulse/client.conf:autospawn=no
    /etc/pulse/daemon.conf:exit-idle-time=0
    /etc/pulse/daemon.conf:default-sample-rate = 192000
    So, there's not much I've done there. Here's the contents of /proc/asound/cards:

    Honestly, I think that's about all of the configuration info I can give. Here are some screenshots of pavucontrol, though, in case you are not yet sated: http://imgur.com/a/ngyLl
    Now, on to the debugging stuff. First: everything except Blue Yeti recording works. The external DAC works, the on-board audio (both input and output) work, using the DAC in the Blue Yeti to play music/monitor the microphone works (so it works as an output). The only thing that doesn't work is actual recording from the Blue Yeti itself.
    When I try to record from the Blue Yeti with parecord -v, I get very strange behavior. Essentially, the "latency" of the microphone measured is exactly the same as the time it has been recording. That is, if it has been recording for 5 sec, then the latency is 5000000 usec. Also, if I try to record something in Audacity, I get no result except for a message box that says "Latency Correction has caused the recorded audio to be hidden before zero. Audacity has brought it back to start at zero." Also, pavucontrol doesn't show an input volume bar for the Blue Yeti, as in the above screenshots, whereas it normally will for microphones that are getting input. The Yeti is not muted, either, so it should be picking up ambient fan noise and such.
    Does anyone have any ideas? Is there some configuration error I've made? Typically, this sort of stuff simply works out of the box for me, so I am somewhat stuck on what to do. Could it be a driver-level bug?

    I'm not sure what you mean by "mixed with audio in Alsamixer". Can you clarify?
    With that said, my problem did mysteriously fix itself after some update (presumably to alsa). Unfortunately, I noticed it in passing one day while I was changing the volume of something in pavucontrol, so I don't remember the exact update that caused it to work. But yes, my current setup does work now: I can listen to audio through my DAC and use the Yeti for recording. However, I have found that use of the Yeti crashes Google Hangouts, although it works perfectly in every other program I've tried.
    As documentation, here is my current working setup (it is very similar to the above): in PulseAudio, the DAC is set to be a Digital Stereo (IEC958) output. The Yeti (called an 'Integrated Rate Matching Hub' in pavucontrol) is set to be an Analog Stereo Input. In the input devices section, I have the Yeti's volume set to around 58% (-14.31 dB), which is past the base volume a fair ways but produces decent levels for recording. The DAC's volume is set to 100% (0dB gain, the DAC takes care of the level). In alsamixer, I have the mic level for the Yeti set to 40.
    Edit: This is a long-time-later edit, but let me say that when you have multiple USB audio devices, what USB hub and in what order they are connected seems to matter a great deal. If you can't get your Blue Yeti to work, try moving it to a different set of USB ports (controlled by a different controller) on your motherboard. This magically fixes the issue for me.

  • How do I plug a non-USB microphone into a Mac Pro?

    Question from an audio newbie....I've got a 2009 Mac Pro desktop computer. I just bought a microphone headset. The headset has a two-pronged plug in, a green one for the headset (speakers) and a pink one for the microphone. My Mac Pro has two speaker ports - one in front and one in back - but I can't find anyhwere to attach the microphone plug.
    I don't want a USB headset because my USB ports are already maxed out. How can I attach this non-USB microphone and get it to work?

    Look at your back side. Look at the booklet too that it came with or from support page manual.

    there are digital out audio and microphone on the backside.

  • Problem with USB microphone on laptop

    I bought a new USB micorphone Auna Mic 900 and I've got a problem... The micprophone is connected and the drivers are also automaticaly installed, but there is no sound coming to the microphone and the microphone is not detected by other programs like Audacity, Skype and more... I tried to reinstall drivers, ban the IDT High Definition Audio Codec and also reinstall driver of the IDT... And I forgot... The microphone is working on oter PC with Windows 7, Windows XP and Mac OS...

    BIOS 2.19 is for X61 series not X60(s).
    Here're my solutions.
    Solution 1. Unplug all USB devices from docking station. Reset BIOS to defaults, save settings, reboot, plug all devices back. All of them should work now.
    Solution 2. Power off your system. Un-dock your laptop. Unplug all USB devices from docking. Re-dock your laptop back again. Power on your system. Plug all devices back again after system booting. All of devices should work now.
    I tested both on my X60s working even if it seems rediculous.
    Lenovo promised to send me a new docking; however, I don't think it will help unless new BIOS is released to solve this issue.
    Note: the kep point is you have to wait to plug all devices back to docking after system boots.
    Good luck.

  • USB microphone with Mac mini - can it work?

    I recently bought a cheap USB camera with built-in mic, and a USB headphone/microphone interface. Neither of these microphones work with my shiny new Mac mini (10.7.2). The headphone USB interface works fine, and it even includes a volume and mute - very cool indeed (Arvel HAMU02BK if you want to look it up). In the Sound Preference pane, it shows up as an input, but the meter doesn't show any response. I plug the same mic and adaptor into a G4 PowerBook (10.5.8) and it works. The camera (Buffalo BSW13K08HBK) also shows up as a mic in the Sound Preference pane, but the meter fails to respond (shows about a 60% continuous input signal, but using it with Skype test, doesn't record anything.

    Camera itself seems to work nicely, though, and there seems to be enough power off the hub to make things work. Is this a bug? If I want to plug a mic into the Mac itself, can I use any of the "pink" 3-pole 3.5mm computer mics?

    Followup - I'm getting:

    on the Console every time one of these beasts gets connected. What to do about this?

  • I bought a Samson R10S microphone to use in garageband on my imac, and i can't seem to get it to record through the microphone, help?

    Need help recording on Garageband with a mic I bought.

    How are you connecting the mic to your iMac?
    Is it a USB microphone or does it need an audio port? The newer iMacs don't have a line-in port, so you'll need an audio interface to turn a USB port into an audio port, eg., the iMic as the most simple solution:

  • USB microphone for Vocals?

    so i just picked up my macbook and im really liking garage band. Now usually im just a natural voice and acoustic guitar kind of guy but im going to give recording a shot. I've been doing some research and it seems like i have two options, buy a preamp and a nice condenser microphone orr a USB microphone. This sounds iffy to me.. I guess what im asking is will i get good sound quality out of it? Would it be better for me to to just get a mic. form the apple store like the blue bird or the snowball orrr just get a preamp from the local music shop or even the icicle xlr to USB converter thats also in the itunes store. Opinions of anyone who has had this predicament would be much obliged... thank you !!

    half of it depends on your budget, the other half depends on your expectations. you should be able to get _really good_ results with a top quality USB mic like the ones shown here:
    http://www.bulletsandbones.com/GB/Microphones.html
    if you have a large budget, something like the Shure condenser in the above list is really top notch (my fav), however, if you then skimp on the interface, you'd be wasting money. iow, the cost has to include the mic AND an interface with excellent mic PREs, something like the PreSonus or Apogee interfaces here:
    http://www.bulletsandbones.com/GB/Interfaces.html
    personally, i'd suggest the USB mic as a starting point. you could always sell it in a year or two if you feel you've improved your recording skills enough to warrant it.

  • D-Link dbt-120 USB Blue tooth dongle doesn't work., D-Link dbt-120 USB Blue tooth dongle doesn't work.

    As many of us know, The Mac Pro has the worst BT signal of all Mac products. It is especially problematic when using Wifi (2.4g), causing the Magic Mouse, Wireless Keyvboard and wireless slate to sluggishly move, or not function at all.
    I just purchased a replacement MacPro (2010) for my aging 2006, and noticed that Mac still has the same issues. Unfortunately, I must use Wifi and especially the 2.4g frequency. My wireless products are 1 foot from the box, and I have even tried removing the side cover on the Mac pro along with the removal of the battery cover on the Magic Mouse. Yes, when I do this, reception is a bit better.
    I know a replacement machine wikll not fix the problem, and Apple has yet to even really address it. I had read somewhere that Apple had quietly supported the D-Link dbl-120 USB BT dongle, so I bought one. When I plug it in, the dongle lights up, but nothing else happens. It does not show up at all in the system profiler for USB connections. All drivers that come with this dongle are Windows based only. Various FAQ's state it is fully compatible with this dongle and should work right out of the box.
    I think Apple needs to update its tagline that state's, "It just works".
    Any ideas??

    I've used a IOGear GBU421* for more than a year now with good results (once you learn to expect some slow MM pairing after sleep maybe 30% of the time).  I would expect the DLink dongle to behave similarly and you shouldn't need any additional software.
    Try doing a smc and pram reset -- the usual first attempts at trying ot fix BT problems.
    Try unparing and re-pairing.  Make the devices favorites.
    If you have xcode installed you can do a bluetooth factory reset with Bluetooth Explorer.  The always works in the few times I had to resort to it.
    With respect to the poor BT reception on the mac pro's, below is a link to probably the best discussion on this where there are posts talking about dongles and replacing the crappy internal antenna with an external antenna.

  • USB Microphone With Garageband & Skype?

    Will I be able to record a Skype conversation using a USB Microphone? Currently, I record using my laptop's internal mic but it picks up the laptop's fan noise.

    Get This skype recorder by ecamm http://ecamm.com/mac/callrecorder/ its only $14.95 and works amazing! I also use a Blue Snowflake USB mic which you can pick up on amazon for $50 and I use for both skype and my audio products I created. Then all you need is your apple earphones so you dont pick up and echo and make sure to have the mic close to your mouth so it gets better audio and no computer noise. This is what I use for my radio show and podcasts.

  • USB microphone recording

    Hi, I recently picked up the HpX360 and there is a problem when I am recording with my Samson Go Mic (USB microphone). There is constant static in my recordings. I know that it is not background noise because this static is occuring when my recording volume is on 0. Secondly, I know it is not the microphone's problem because the microphone works fine on my friend's laptop. I've tried uninstalling and reinstalling both the sound and samson go mic drivers. I've tried using different USB ports. I've tried changing the sample rate and the bit depth, but the static is still there. I'm wondering if it is an internal error with my laptop? Any help would be greatly appreciated.

    Problem 1. You can't normally alter the level of a USB mic via the usual Windows Sound Mixer page since USB audio goes direct digitally into Audition not via your on board analogue sound card.
    Problem 2 is a fairly common problem using USB audio devices with laptops. May go away if you run the laptop from it's internal batteries rather than from the mains supply.

  • Does anyone know yet if the new iPad will support a USB microphone plugged into Garageband via iPad's USB Camera Adapter?

    Hi,
    I've ordered a new iPad 64Gb which will arrive early April. My hobby is making music, so does anyone know yet if the new iPad (3rd generation) will support a USB microphone plugged into Garageband via iPad's USB Camera Adapter? I am hoping to use such a portable setup to record live performances of voice & acoustic instrument.
    Thank you,
    John.

    When in doubt, try it out. I bought the Apple camera connection kit & used it to connect my Blue Snowball usb mic to my new iPad 3rd generation. It works just fine. I made some test recordings in GarageBand on my iPad 3 using my Snowball mic. They sound great.

  • USB microphone with adobe flash player on chromebook

    I am using fash player to record a youtube video on my samsung chromebook. I am trying to use a USB microphone to do the recording. My chromebook recognizes the USB microphone when I plug it in and I select it in my chromebooks taskbar and select it as the audio input source. When i go to record my video on flashplayer and select the microhpone in flash player icon the only option I have is default. Does this mean I cant use my USB microphone or does default refer to whatever microphone i have selected in my chromebooks preference as the audio input.

    What are microphone settings?
    Microphone settings allow you to select a microphone, adjust its sensitivity, and reduce the echo that may be coming from your speakers.
    What happens if I do nothing?
    Adobe  Flash Player automatically detects any default microphone or other audio recorder on your computer, and sets microphone sensitivity to a medium value.
    Note that Flash Player asks your permission before allowing an application to access your camera or microphone. See Privacy pop-up question.
    What can I change here?
    You can select a different microphone, adjust microphone sensitivity, and reduce echo. The settings you select here apply immediately to the active Flash application. To change the default microphone, select another microphone from the pop-up menu.
    To test your microphone, speak in a normal tone of voice and watch the indicator on the left. When the indicator shows yellow, your microphone is sensitive enough for Flash Player to pick up sound. To increase or decrease your microphone's sensitivity, move the slider to the right or the left, respectively.
    If you are using speakers instead of headphones, select Reduce Echo. Reducing echo has the effect of reducing the noise coming from your microphone through your speakers.
    What if Flash Player doesn't find a microphone?
    If Flash Player cannot locate a microphone or other audio device on your computer, the player displays the warning "No microphone detected." Read the documentation for your computer and your microphone to make sure your microphone is installed correctly.
    How do I test my speakers?
    Click Test Speaker in the application shown below to hear a sample sound. Adjust your speakers or headset so the sound is at a comfortable level.
    How can I display this panel again?
    You may want to display this panel again if, for example, you want Flash Player to use a different microphone. To display the Microphone panel:
    Right-click (Windows) or Control-click (Macintosh) the application image while it is playing. 
    From the context menu, select Settings, and then click the Microphone tab.
    I don't see the Microphone tab, so I can't display this panel.
    If your computer or device doesn't support audio recording using Flash Player, you cannot select a microphone to use, and this panel doesn't appear.
