Extraction of Audio from .wmv Video File

Hello Everyone,

  I have a .wmv video file, and I want to extract just the audio from the the file, and save it preferably as an .mp3 audio file. Does anyone here know which freeware or free software can do this?

  Thanks as always. Rocketshiporion♫ 05:46, 31 May 2011 (UTC)

MediaCoder should do this; and Handbrake might (haven't tried it with WMA files). I don't think this works if the source is protected by DRM, however. --Kateshortforbob _talk 10:53, 31 May 2011 (UTC)

MEncoder and Avidemux are two more. I just tested the freeware version of AoA Audio Extractor and it also works very well, and with an easy to use GUI AvrillirvA (talk) 11:16, 31 May 2011 (UTC)

I've downloaded and installed AoA Audio Extractor, and it works well. Thank you, AvrillirvA! Rocketshiporion♫ 13:01, 31 May 2011 (UTC)

AKME FFmpeg has worked well for me.... Kingsfold (Quack quack!) 18:53, 31 May 2011 (UTC)

vst plug-in

Does anyone know of a vst plugin (free) capable of real-time boosting a range of frequencies by a given amount of db? Say 0-90hz by 6db.

Can't seem to find any that do this.

Thanks. — Preceding unsigned comment added by 77.35.19.235 (talk) 07:23, 31 May 2011 (UTC)

If by "vst" you mean Virtual Studio Technology then I guess you need a graphic equaliser plugin. Searching Google for that finds Voxengo's MarvelEQ, which is free. -- Finlay McWalter ☻ Talk 20:37, 31 May 2011 (UTC)

Your DAW will almost certainly cater for this, whether it's a built-in function or plugin included with the software. In this case, you'll want to use a low shelf filter and set it to boost below a certain 90 Hz by 6 dB. If you need any help finding how to do this in your software, I'm happy to help. However, as you refer to VST (which is a trademark of Steinberg) I presume you're using Cubase or Nuendo, in which case you'll find the EQ in the left hand panel. This Sound on Sound article gives an overview of how to use EQ in Cubase. matt (talk) 21:41, 3 June 2011 (UTC)

how to remove old mobo/processor information from a WinXP installation?

I changed my mobo and processor from a very old Intel 845GLLY + P4 to an Asus board + Dual Core. I keep my old hard disk. Can I run the old installation on this newly configured system? When I switch on the system the blue screen of death only comes. Can I remove some information from the old installation using Puppy Linux or some other tool so that the windows XP would run on the new system? --117.253.191.4 (talk) 08:32, 31 May 2011 (UTC)

If you have your XP installation disk, boot from that and try doing a repair installation. I will warn you if it is going to wipe your hard drive - in which case, abort the install and use Puppy Linux to back up your stuff to another disk/USB stick/memory card/etc. You can then try the repair again. Having changed the motherboard, it is likely you will have to re-activate your XP installation. That process is fraught with difficulties if your XP install disk is an OEM version.

Specific URL problem

If I browse to The Advertiser newspaper site (http://theadvertiser.com.au) , using Linux and Firefox, the website generally refuses to display anything, with the browser saying "Waiting for resources2.news.com.au....", however if I use Windows XP and Firefox (the same version as Linux) the site immediately displays correctly. Very occasionally the site will display correctly under Linux or more frequently, it will display badly formatted, and with most of the images missing. Does anybody know why this might be the case? Is it my Linux configuration? Other browsers running under Linux display similar results. Other newspaper sites work fine. Thanks! --TrogWoolley (talk) 11:05, 31 May 2011 (UTC)

I only have Linux and it looks fine to me. It is probably some ad that is Windows-only. Add an ad blocker to Firefox to take care of that. I have to say that after looking at the page, I'm now rather upset that the American media hasn't said much of anything about the Australians killed in Afghanistan. -- kainaw™ 12:29, 31 May 2011 (UTC)

Displays fine on Unbuntu/Firefox. Some other websites though... Astronaut (talk) 16:01, 31 May 2011 (UTC)

I have Fedora 12 Linux and FireFox 3.5. The link directs me to http://www.adelaidenow.com.au/, which displays all OK. I only looked at the front page and didn't actually try to read any articles though. JIP | Talk 19:00, 31 May 2011 (UTC)

Automatic mounting on Linux triggered by device being already mounted?

I think I might have found a reason why the automatic mounting on my Fedora 12 Linux system keeps turning on and off. I just backed up my hard drive to my external hard drive, with the automatic mounting having turned on, and when it had finished and had unmounted the drive, I ran mount with no parameters and it said that /lacie2 (a common mount point I use for the external hard drives and the camera, although the camera is an Olympus and not a LaCie) was still mounted. I unmounted it manually, and the automatic mounting turned off. I then plugged the camera in, and Linux didn't automatically mount it. I mounted it manually, and unplugged it without unmounting it. (This can cause problems if the file system has been changed, but I remembered this and didn't change it.) Sure enough, when I later plugged it back in with /lacie2 still mounted, the automatic mounting had turned on. What could be causing this? JIP | Talk 18:50, 31 May 2011 (UTC)
