The microphone volume

Are there known issues with the microphone volume fluctuating on the device? My duties sometimes report a wide range of amplitudes for ambient noise even if the actual noise levels did not change significantly. I'm pretty confident my algorithms are correct and bug free.

Is this a known issue?

I think that the microphone has AGC (automatic gain control).  A few months ago, I took video with the playbook of a violent storm with heavy rains and record, you could hear the rain, but when loud Thunder came, you could hear it very well (no cutting), but we couldn't hear the rain.  Like the sound of Thunder disappeared, the "rain" volume came back upward.  It's so good that I think that it's hardware and not software MCO.

  • The microphone volume is very low on a Dell inspiron 13 7348 with Windows 10

    On my new Dell inspiron 13 7348 the microphone volume so low that my Skype partners can barely hear me. I checked all the settings in Skype and software audio dell and I updated all drivers... without success

    Connect a microphone extermal solves the problem, however, I prefer to not always have an additional microphone with me!

    Has anyone found a way to increase the volume of the microphone?

    Since an external device works well I'm afraid that the build-in microphone is actually of minor quality... what a disappointment

    So far, nothing has changed. I continue to go all my encounters with my laptop and this webcam with microphone build - in which I used the last in 2005... It's ridiculous... Don't know how many times I have had to explain to my colleagues why I use this external microphone... BTW, their Skype works well on non Dell computers with Windows 10 so I guess it's a problem that only affects users of Dell...

    As I said before, it's a big disappointment, and in the future I will avoid Dell products.

  • Satellite A100-532: the microphone volume is extremely low

    I just bought Satellite A100-532 and I have a problem with the audio input. I can't use the microphone to chat with my friend on msn or even record my voice on the hard drive because the volume is extremely low.

    I tried to turn the volume on the desktop and on the RealTek HD audio Manager, but nothing helped. Microphone works perfectly fine, as I hear myself on the speakers.

    Normally, with my old laptop (M30 series) I could use sound recorder to record the music that I play using Winamp or WinMediaPlayer, but for this new laptop it detects all the sounds at all... just silence.

    Please notify.

    Hello

    You should also check the volume controls in the "Audio & Sound devices" in the Panel.
    In the 'Volume' tab it please go to "Advanced".
    Then a "Volume control" should appear.
    Check if all controls are set at a high level.
    In addition, enter the 'options' and 'properties' and activate all volume controls.
    Also change to "recording" and activate here also all the controls.
    Additional you must check if the "check" is set to high.

    Use the 'Advanced' mic option and play with thrust mic settings.
    I'm sure that you will find the best settings for your mic record

  • Too low volume of the microphone

    I just bought a new Toshiba Satellite L500D, with Windows 7, and I'm having a problem with the microphone volume, in this sound recording is barely audible.

    I followed all the steps suggested on this topic on the forum: http://social.answers.microsoft.com/Forums/en/w7music/thread/06582922-0014-4dac-9f74-b63f143fbb8e... .but nothing fixed it.

    It's a built-in microphone and audio driver is Realtek.  I did a driver update check and it integrates the latest version.  I all set to maximum microphone volume settings and tried to test records Skype and sound recorder for Windows.  They record, but it is extremely low volume, even if I'm leaning closer to the microphone and speak loudly.  Different recipients of Skype call could barely hear me.  The only thing that saves the high voice is when I run a finger over matte plastic of the monitor frame - which saves super hard for some reason any.

    I welcome suggestions as soon as possible.  I need my microphone to get the work done!

    I hope that the people at Microsoft can remedy the situation as soon as possible, because it is crucial to set!

    I had this problem for a few weeks, I recently read a forum post saying uncheck the: allow applications to take exclusive control of the device:

    Well, I found this setting and changed a few others and I think that he has fixed

    I went through the control panel > hardware and sound > manage Audio devices to reach the acoustic Panel.

    I selected reading > Speakers > improvements and made sure that everything was unchecked.
    "" I selected reading > Speakers > advanced and unchecked "allow applications to take exclusive control of this device.

    I went to recording > Microphone > listening and insured 'listen to this device' is unchecked.
    I went to levels and assured the Microphone level was 100% and the boost to + 10 dB
    I'm gone into improvements and assured that everything was unchecked.
    "" I then in Advanced and unchecked "allow applications to take exclusive control of this device.

    And finally I went in the Communications of the acoustic Panel tab, changed "when windows detects communications activity" to "do nothing".

  • Satellite C650-197 built into the Microphone and Jacks does not

    As the title, I tried to use the microphone that comes built-in on this model (Web camera VGA integrated with built-in microphone) and found his does not work. I tried to plug in an external microphone via the microphone jack and still no registration.
    I can't seem to find the drivers for the integrated or plug anywhere.

    Any ideas?

    Hello

    > I can't can't find the drivers for the integrated or plug anywhere.
    This drivers don t exist. The sound card driver controls everything.
    I think you should first start the webcam software and should test the microphone because the internal MIC is part of the webcam.
    Webcam software provides a tab; settings and properties. In one of these tabs, you will find settings for the audio.
    Here, you can increase the volume of the microphone and was able to record a small audio session.

    In addition I recommend the settings in Control Panel-> sound.
    Make sure the microphone volume is set to maximum. Don't forget to check the hidden devices and disabled it there...

  • Low Microphone volume, only in Skype

    Can anyone help?

    In Skype, my laptop's built-in microphone is intermittently from low level. The microphone level is OK in other applications for example, Audacity.

  • Test the microphone works, but I can't save with recorder to the computer.

    I tested the microphone under voice identification. He says he works. When I opened the computer of the recorder of the window and click on 'start recording' nothing records. Also in my music software Sonar, the microphone no longer records. I went to 'troubleshooting' and the final message said: "the volume on the unit is low." Not fixed. How to increase volume for a microphone? I understand how to increase or decrease the volume of the speakers via the speaker ikon down in the corner, but you can never asked me to change the microphone volume. How do you do that? (If that's the problem!) Thank you. Operating system is Vista.

  • Change the volume of the microphone

    original title: microphone make it stronger

    How do you make your mic harder and get rid of the noise.

    Go to start / Control Panel / Sound / recording devices and click the device you want to adjust, and then click Properties, and then click levels.  You will then see a scroll bar to adjust the volume of the microphone.  Click Custom to enable the Microphone Boost.  Click on advanced to select the sound quality in a menu drop-down (another quality can eliminate the noise).

    There may be other controls according to your device (or there may be less, or they may be arranged differently) - but for the most part, this is the place where you make adjustments.

    I hope this helps.

    Good luck!

  • Portege S100: Could not get the microphone work

    Unable to get a response when trying to record audio. Have tried the Windows sound recorder, the recorder in OneNote and a Creative Writer with no luck.

    Have adjusted the volume - increase levels of reading and recording settings and clicked on 'choose' in the recording settings. Have you tried an external microphone. Have tried with computer attached to the port replicator and taken in isolation.

    I forgot something obvious?

    Hello

    I guess you can hear the noise and the audio driver is installed correctly.
    In Control Panel, you will find the SoundMax.
    Here, you can try to start the configuration of the Microphone. Also check the improvements of Microphone. There you can activate the recording of voice option
    On the power management tab, you need to change the option to no energy saving

    The other possibility is to check the Toshiba Mic Effects. Check if the Mic controller is set to max.

    Hello

    What a problem? Do you think that it is really a problem or perhaps only a configuration setting bad microphone?
    I think that he just misconfigured s mic settings!

    If you use the external microphone, you should check the settings in the-> sound & audio devices Control Panel.
    In the Volume press tab on the Advanced button and check if the Microphone control is not mute.
    Use the Advanced button and the brand, select options called Mic2 and mic amp.

  • Equium M50-216: cannot save or use the microphone or "phone entries

    I have an Equium M50-216, with 1 GB of RAM & Centrino 1.7 GHz processor, running XP Home.

    Without apparent reason, I am suddenly unable to use my SKYPE USB ' phone to talk. Audio output is perfect, however.

    I also tried my helmet using the jack on the front of the laptop, with the same result.

    I downloaded and installed the latest driver for the sound card, which is a Realtek AC97. I tried the test equipment of Windows, but there is no evidence of entry he built in sound recorder, audio, or in windows.
    The device driver is properly enabled and reported no problems.

    Is it a hardware problem - as it seems card works OK for output?
    Is it a Windows problem - I can achieve a reformatting the drive & re-install of XP soon - it would help?

    Hello

    As far as I understand your problem, you are not able to use the external microphone. Am I wrong?
    You mean that it's a hardware problem, hmmm I n t think so.
    To me, it looks like a wrong setting

    Please check if the microphone is activated. This should be verified in the--> sound & audio devices Control Panel.
    On the volume tab, press the Advanced button.

    In the options settings, you can switch between the playback volume controls & record.
    Please check everything!

  • Satellite C660 - 18 c - can't get the microphone to work

    So, I couldn't get the microphone to work so I bought a new one. I also can not get this to work. I tried everyway I can think of and he will simply record is not all sounds and yes the microphone is on and the volume is full.

    Can someone please help me solve this? Its driving me crazy!

    Hi belthazora,

    Just to make sure that we are talking about an external microphone that you have connected to the microphone jack and not internal? I ask this question because the laptop doesn't have the internal mic.

    Anyway, if you use an external microphone ensure that it s listed in sound devices under the recording tab. You see it there?

    I also recommend an update of audio driver if it doesn t work. You can download all the updates on the official page of Toshiba:

  • I can not turn off the microphone on Satellite p100-194

    No matter what I do, I can't turn off the microphone of shit, he's always watching on my speakers, I have all the right settings in the sound control panel... believe me!

    Does anyone know how to disable the security...

    * monitor on my speakers even when I uninstalled all the sounddrivers! ... * it seems to be a bios problem... HEEEEELP!

    is there perhaps a bios fix?... or no solution at all on this model, I use win 7 32 bit...

    Hi leon-k,.

    Usually, you can cut the speakers in the Windows sound settings. Go to control panel > hardware and sound > sound.

    Now, choose the recording tab as Akuma written and click Properties > listen. On this tab, you can change the volume and disable the microphone set.

    Check this box!
