  1. I installed this V4W on my PC Windows 8 Pro 32-bit,
    I enabled V4W and adjusted adjusted settings of my desire.
    But I noticed no difference when enabling V4W or when disabling it, tried to hear difference when V4W is ON and OFF mode.
    No difference.
    Plz give solution

    1. Sadly ViPER4Windows only works with stereo channel setup, i really hope that they are going to fix this!! I had the same problem as you have right now,
      please admin add support for more channels! Maybe ask for some help, i can help you with programming some things if you want too.


  2. Congratulations!!!
    I installed on my samsung galaxy note 2 i317m and my laptop HP pavilion.
    This shit rock’s!!!!
    Greetings from Mexico and sorry for my bad english.

  3. I don’t know if this is the correct place to post bug,
    Everytime i reboot the pc I lose all the setting, the app revert back to default setting and when i minimize the app i got this: error Technical Info: Access to the path ‘C;\Program Files(x86)\VIPER4Windows\LocalPreset.bin’ is denied

    I tried:
    Installed as administrator
    Installed in paths: Program\VIPER4Windows Files and Program files (x86)\VIPER4Windows
    Change permission of the VIPER4Windows’s Folder

    My Pc: Windows 8 Pro x64

    Any Info that you need let me know

    1. For your error, when you want to run Viper, right click and click “Run as administrator”.

      When you run it as the Administrator, you will no longer get the error messages.

      1. The channel output is limited to stereo at my system. Using SPID/F or something else, except for the headphone output (the green ones) I don’t get ViPER Enhanced music :-(
        Even when I run it as admin

  4. Installed it on my Windows 8 32bit system (VIA sound card) with an Altec Lansing speakers. The verdict is ‘marvelous’… ‘Outstanding’. I used the HTC ver2 Veats IRS convolver. Nice job done….

  5. had it on my galaxy mini..
    pc version works perfectly..just 1 thing maib it shld run at start up,tried adding it myself to strt folder bt it still dint start.great work!!!

  6. how do i install viper4windows on windows 8.1….. before i had windows 7 has my operating system… on win 7 it used to work alright… but after i installed windows 8.1 viper4windows has no effect…. i have .net 2.0 installed also while installing i have run as administrator…. even while running the program i have run as administrator… still no effect… i have realtek audio drivers installed too… i have run the configurator and installed on all devices still there’s no effect…. how do i fix this??

      1. Of coz I did, if not I wont be able to hear sound from my speaker… Btw, my sound card have feature like ASIO. But Im running Foobar2000 for my music, I don’t think my player is running with it.

        Until now, still have no effect.

  7. I want to thank you. I want to deeply thank you for this marvelous piece of code!
    I’m audiophile and I love this. Forget SBX Pro Studio, THX Pro, Dolby Headphone and what not.
    Viper sounds better!

    And it even is for free AND for my android tablet as well. Hell, you are my heroes!

  8. For some reason Viper4Windows does not play well with Xbox Video. I cannot play a video with it installed. As soon as I uninstall it, it starts working again. I also get an error when minimizing Viper when it is installed.

  9. Just wanted to let you guys know I finally got to run it on Windows 8.1. Apparently it doesn’t work with the sound drivers coming with the OS, had to install Realtek drivers first and Viper afterwards. Works like there’s no tomorrow.

    Thanks for this wonderful piece of software!

  10. Hello Zhuhang can you tell me how to submit a bug report so that I’ll, because I feel that this doesn’t work on my Lenovo Z570 Win 7- 64-bit.

    ***Works great on Android device (Micromax A110) ***

      1. I am a real fan of your app for android , but I can make it work in win 8.1 (IDT – Beats audio) , the APO in viper’s audio registry is linked to SRS LABS (through configurator i believe ) but still no difference , it works fine in win 7 and realtek audio. Can you please do something about it.

  11. Thank you!! You made me like my XFI Xtreme Audio for the 1st time in 5 years!! :D
    That’s a hell of a accomplishment, belive me. xD

    BTW, working perfectly in Windows 8.1 64bit, but i needed to install the creative drivers, it doesn’t work with the windows default driver, this may be the problem of some people.

    Keep the good work

    best regards

  12. Guys, any chance you are working on a OSX version? Currently the only thing we have on Mac is this app called “Boom”. It’s just a simple EQ. Would be awesome to have the kind of flexibility offered by Viper :)

  13. Hi Viper4windows is not working for me anymore since i’ve updated to Windows 8.1. I even installed general drivers from Realtek’s web page. Now the only way to hear Z convolvers is on foobar2000. I’m a donor, my paypal mail is alejandra.poot@… Just saying. Anyway still enjoying your irs. Viper4Windows still working on Windows 7 though.

  14. This software is simply amazing. It is BETTER than MaxxAudio 3 and Dolby combined, and comes with a lot more options as well as being easy to install and use. My only gripe is that I cannot pair it with the MaxxAudio 3 (I can use the Dolby enhancer) so that I can get even heavier equalization. Honestly, Realtek should ignore the other companies and just pay the developer(s) to put this in their drivers…or just have these developers make drivers for them.

  15. I have viper4android and it’s awesome. But did not know that there was one for Windows till I happened to come across it. Downloaded it and installed it. It works perfect no problem what so ever. Works well with my 8″ Logitech sub and speakers

  16. Hi, i have problem with Viper4windows for windows 8.1. I have Realtek High Definition Audio. When I press the power button there is no difference. I run with Administration rules. I run it with administrator rights. Pls helllp, because is the best software.

  17. Not working for me on my HP desktop. I installed realtek drivers, disabled enhancements, and no option under viper ui changes any sound levels.

    When I uninstalled the realtek drivers and windows automatically put normal HD audio driver in that comes with the OS. Viper audio does take affect, but the x-bass option causes issues with the sound quality.

    OS: Windows 7 pro x64

    What is weird is that it works fine on my lenovo laptop that has Win7 Pro x64, then again it has a different driver for audio since it is a different brand than my desktop.

    Any suggestions?

  18. Hello, friends I have installed in windows 7 x64 ultimate edition with SP 1 . I have sound blaster live 24 bit, but I don’t get nothing effect.
    In viper4A configuration I check up SB audigy and realtek high definition speaker, but can’t. Get nothing effect

  19. Absolutely great piece of software. This is amazing. Far greater than Dolby Home Theater. But please add this to install instructions, because I had some issues at the beginning:

    YOU need to reinstall original drivers – so it wont be some universal Microsoft ones.
    After this you can enable/re-enable Viper.

    Thank you very much also for Viper4Android it’s the best.

  20. Viper4Windows worked perfectly when i has windows 7 64-bit in my laptop,but then when i upgraded my laptop to windows 8.1 there was no difference in sound.
    Please fix compatibility issues with Win 8.1 as soon as possible.We miss best Audio effect software!! ;(

  21. Having issues with trying to get viper4windows to run with my win 7 64 bit its not changing anything in the sound quality or anything i have conexant high definition smart audio 221 any help thanks!

  22. Hey guys,

    I’ve just installed Viper4Windows on my gaming pc because of it’s quite better than any other enhancer like DFX or anything else. It rocks. I’ve noticed that you can set it up in 3 different modes, in which it sounds different each other even if the settings are the same.

    In case of positional audio with stereo headphones, I’d like to ask you what the best settings are with normal stereo headphones.

    I mean, I tried Virtual Surround Sound with viper, but like Razer Surround Sound, I’ve got a delay which makes the game unplayable. But aside this, V4W is a great piece of software.

    My problem is, I can localize of enemies are on the left or on the right, but not that good how far they are away so it’s not that precisely. What would you recommend me to do to get a better positional sound, with stereo or virtual surround sound (but without any delay)?

    Btw: I use onboard sound and if I’m trying to set windows sound to 5.1, viper’s not going to show any effect, unlike razer surround sound because it simply needs 5.1/7.1 output.

    I hope you can help me because I love viper.

    Thanks in advance

  23. Finally found it a solution to make it work on windows 8.1

    Download SRS Sandbox Audio and install it
    Install viper and choose audio device
    Afters restart turn off SRS and turn on Viper and it works!
