Adding personal Audio

I want to take a part of an audio file from a video and use it as my into when i start my comp up.
Can anyone help me do that. I know where to add it but i don't know how to get the audio from the video separted.

I'm not sure about making your audio file but I do know that to change the logon sound in windows you go to the control panel -> sounds and in the sounds tab look for windows logon and you can change the sound there. Looks like it only accepts .wav sounds so they are going to be fairly big files. Personally I have mine set to "No Sounds" out of personal preference and having logon/logoff sounds increases the time it takes to turn on/off my comp so with that said don't have your sound be too long.

Or do you know of a program that lets you record the audio on the screen that id currently laying. ex a tape recorder next to the speaker"

"I dun get id", wise words which once left the mouth of a, possibly not up to the standards of his words, wise man.

Words one could usually expect to come from the person one would be trying to help if not more effort than a simple pointer into the somewhat right direction is involved, eventually leading to the person in dire need of help to get lost in what could most likely be defined as a desert of thoughts, resulting in the above mentioned person's thoughts becoming pirated by giant ninja sandworms, leading to the loss of possessions, for the persion in question, which are required for the whole scenario to happen in the first place, resulting in a neverending loop of mental degeneration.

Talking about loops, a loop is exactly what you need to do if you want to extract audio without going through the annoying process of, for example, removing the video information in the act of converting a video to an audio exclusive format.

My question is, are loops which are only loops for a short period of time, since they're eventually coming to an end at some point, actually loops? Well, we'll find out about that now. Or not.

Audacity is definitely a piece of software worth to be recommended, and it's also what I'd suggest you use to solve your little problem.

Down to the basics, there are two directions sound is generally heading. Those direction are called Input (Sound going in, as in recorded.) and Output (Sound leaving the system, eventually coming out of your speakers.) - so, after some quick brainstorming, the easiest solution would be turning Output into Input, makes sense?

Go into your OS sound settings, mute all your usual recording devices which function under input (Like microphone, if used. May vary depending on hardware and/or operating system.), set it up for your input to listen to some output device instead (Again, may vary. See spoiler below for an example.), tell Audacity to use exactly that device for recording (See spoiler below for an example. Again.), and simply play the video part and have record up on audacity at the same time, and I supposed you can work it out on your own from that point on.



There are we coming to an end of this supposedly neverending loop scenario. That wasn't a loop at all. Apparently, I lied. If I lied to myself without further effort of tricking myself into believing it in the first place, does that make me a fool? I suppose not, since the moral of this story is one of entire difference - if you don't bring a guide into your imaginary deserts, you'll be eaten by ninja sandworms.
