Hi all

I want to read a signal on the sound card, an FFT and then do a weight!

However, I don't know how I can set the full spectrum to get a dBA as a result value.

I've attached an example of VI...

I hope someone can help me!

A big thanks (and sorry for my English :-))

    I confused m do you know why?
    Because you talk about audio driver Realtek and sound chip and my knowledge, that the Satellite Pro P300 was equipped with the audio chip Conexant!

    It s NOT the Realtek chip! It s Conexant!

  • ATTENTION TO DEVELOPERS - PROBLEMS WITH THE SOUND CARD

    I have a Focusrite Scarlett 18i6 audio card. I have before running on my Mac, version 5.0.3 (VMWARE) and everything worked. After that I updated to the new version 6 and my sound card no sound comes and has connectivity problems in windows. I updated the drivers for my Board to the latest version. I've upgraded to the last version firmeware. And I tested this audio card on two different Macs with version 6, and the problem persisted!

    Note: I use demo version 6.

    The sound card works perfectly in my MAC system with the latest drivers. But the problem remains FUSION version 6. I tested it on two different virtual machines with different operating systems, tested on two different Imacs and nothing back to work as before.

    After several tests, which detects the sound card works perfectly with his last official update from the manufacturer only with version 5.0.3 (VMWARE). With version 6, the problem persists.

    I am desperate because I work with music production and use software for windows in my MAC...

    Sorry writing errors. I live in the Brazil!

    Version 6, it must improve the compatibility issue. Problems I am facing a lot after this update.

    Before uninstalling VMware Fusion 6.0 you must change the updated hardware Version from 10 to 9 for any Virtual Machine level.  Take a look on: Change the compatibility of a Virtual Machine

    Then uninstall VMware Fusion 6 and then install VMware Fusion 5.

  • Problems of thw whole adter computer tries to right the wrongs of a virus by reinstalling Windows XP. Especially with the sound card and microsoft components.

    I had some virus that wiped out my computer and began to delete files .exe for evrything and started to interfere with my network connections that made me unable to get on the internet. I've got rid of the virus, but still not able to get on the internet, so I decided to reinstall Windows XP from the service pack CD that I got with the computer. Now that I did it, it seems that all the components of windows have disappeared from my list of programs in the control panel. I still have everything that was on the hard drive on it, but I can't seem to get things to transfer to the new XP operating. My biggest thing I found is that my soundcard has seemed to disappear and my volume control will not work because it says I have no mixers or equipment installed. Help, please.

    You don't have a clean install of Windows. Backup your data and do a clean install according to the instructions below. Once installation is complete, you will then need to install the drivers for all your hardware.

  • I need is no longer dial-up moden in my computer. Can I remove it and replace it with a sound card?

    Windows Vista SP2 64-bit

    HP Pavilion a6622f Desk Top PC
    Serial number: [personal information]
    Product number: FK567AA

    If you have a sound card that fits into the PCI slot, it looks like this modem is in, then Yes, you should be able to remove and add the sound card. Please keep in mind that the motherboard has a built-in audio chip. He works? If so, you may need to check if your model BIOS has an option to disable audio integrated.

  • Equipped with a sound card has lost after upgrading graphics card

    Hello

    I lost my sound system after updating my video card, a Sapphire HD 5450 1 GB DDR3.

    I already tried to get in my BIOS, but I need to enter a password and I don't know the password?

    Also, I upgraded my BIOS before moving my graphics card. The latest BIOS for an HP dc7700 SmallFormFactor.

    Please help me, I can't play without audio... There is no fun to play games without sound...

    Hello:

    It is a problem common when you add a video card to your trusty old dc series business offices that were not intended to this new technology as HDMI.

    Not only don't the PC think you added a video card, but he also thinks that you have added a sound card since there is a HDMI audio chip on your video card Platinum.

    If the PC BIOS disabled onboard video and integrated audio system.

    This is why you have no sound.

    So, now you know why it's happened, let's go in and solve the problem in a jiffy.

    Restart your PC and press the F10 key to the HP welcome screen to enter the BIOS.

    Go to the Advanced menu and find the onboard audio setting (appeared as if by magic, now that you've added the video card).

    It will be set to Disabled. Change the setting to "Enabled". Save the setting it by hitting the F10 key and resave the settings when you exit.

    Reset and you will have your on-board audio back.

    To clear the BIOS password, shut down the PC, unplug and remove the Green password on the motherboard jumper.

    Restart the PC without the flying connection and the P/W should be cleared.

    Then shut down the computer, unplug it and replace the Green jumper on the pins that you deleted since and he put it back together.

  • Satellite L755-16J - problem with sound card

    I currently own a Toshiba * Satellite L755-16J * and is having some kind of trouble with the sound card, I think.

    When I bought it, it came with windows 7, I changed the Windows of windows 8 and since then the audio has been trouble me.

    The internal speakers work for a minute or two, when I play an audio file, but then stop working.
    I had been using a usb external sound card and external speakers for some time but decided to the switchback to windows 7 for the sound working again. even if I went to win 7, the sound still doesn't work.

    I am sure that the problem is not in the internal speakers because they do not work, even if it's just for a brief moment, but they work, so I think the problem is in the software instead of hardware.

    I tried to update the audio drivers but they seem to be updated as windows, pilots 'seem to work properly.

    Can anyone help?

    > even if I spent back for win 7, the sound still doesn't work.

    How did you do that?
    Have you used the Toshiba Recovery disk in order to install Win 7 or have you installed Windows 7 using the Windows 7 clean and fresh hot?

    The laptop supports the Conexant audio chip. The audio driver is available on the page of the Toshiba UE driver and where the sound chip is already recognized in Device Manager after installing the audio driver, I assume that the driver has been installed correctly.

    In this case I recommend you plug in a headset.
    In case the headset should work fine, the speakers could be affected. I mean the material. But of course it s just an idea.

    Next to the audit of the helmet, you can also check the settings in the Panel of-> sound-> the Read tab.
    Usually, the speakers should be set as default device.
    Check this option too.
