How to get audio from video

[normvork]

I just learned about ways to get videos downloaded from Youtube. What if all I want is the audio part of a video? Can I take the audio from a digitized video and have it in its own file? How?

The easiest way is to simply record the audio while the video is playing. This is easy in Windows, but a bit trickier in OS X (requires Audio Hijack or similar app).

Thanks Graham, I like easy. Could you elaborate a bit on that? I have Windows, Acid and Audacity. How would I go about playing and recording simultaneously?

I can't be sure as I don't do much audio in Windows anymore and it varies a lot by system, but I did this before by loading the web page in my browser, and hitting record in Audition (Audacity should substitute for that nicely). Depending on your computer, you may have to select a specific recording source and/or adjust the Windows mixer.

Your question finally prompt me to find out how to do this, something I've been meaning to do for a while now.

I know that the VideoWave portion of Roxio software allows the extracting of audio (wav) from any .Mpeg or .Avi video clips. so..

Since all Youtube downloads use .FLV (flash video) format, I just did a search for a .Flv --> Mpeg or .Avi converter to use with my Roxio and found many, but downloaded this free one..

Riva VX: Downloads

I took a Youtube dowloaded .flv file (France Joli's "come to me" )and used Riva to convert to Mpeg, then find and open up the newly rendered Mpeg video with VideoWave which is part of the Roxio suite, all you do next is 'right click' on the Video file (Mpeg) and choose "extract audio" , pick a location and is done.

I'm using an old version of Roxio's (7.0) 'Easy Media Creator Suite' and just purchased version 9 for 50.00 @ Best buy, (with a Roxio rebate of $20.00 for previous owners my final price will be 30.00)

I'm yet to install V9, but according to the info on the box , this version is able to 'capture' any streaming audio playing on your PC, I wont know for sure or how well this works until I play around with this latest version.

reading other posting , apparently there are a bunch of free ware that should be able to extract audio without using Roxio, but this is going to require lots of research and experimenting time.(what else is new)

For instance, someone in a forum indicated that "Audacity" is able to record (extract) audio from .flv files directly, I downloaded Audacity (free software) a while back and try to do it just now, but it didn't work for me.

I'm afraid this is going to take hours of experimenting to find out..

Here, all this info I got from just this one thread, and Google came back with hundreds!!

By the way..

What method are you using to download YouTube videos, I'm using a plugin for FireFox that is very simple, but I'd like to figure out how to do it under Windows Explorer. (IE)

Even though the above described methods work, recording from a Youtube video stream can be achieved without having to go through the tedious steps of conversion.

BUT, (there is a BUT) you need a sound board that supports "patching" or "routing" of the audio stream.

If you don't have this capability jump below for an alternate method.

Step 1: Start your preferred editing software (Nero Wave Editor, Sound Forge, etc.)

Step 2: Select the proper input to be patched into the software (usually located into the <options> tab)

Step 3: Begin the recording on the audio software

Step 4: Start the Youtube video and...voilà! you can make on-the-fly recording.

All is left to be done is trimming the quiet passage at the beginning and the end of the audio clip.


Alternate method:

Before I purchased my multiple inputs sound board (with the patching capability described above), I used to use a piece of software called "VIRTUAL AUDIO CABLE" (Virtual Audio Cable Home Page). Its is a pretty cheap software considering the time savings you can make.

As it is explained on their web site, it allows you to take what is outputted by the sound board and virtually feed it back into your favorite software, (as if it would be from an external audio source).

All this is done without loss in quality, no need to save or convert the FLV file onto your hard drive.

It works as good as the method I described above.

Keep us posted on the progress!

How about that !!

I didn't know this, for some reason I always assumed my M-Audio Audiophile 2496 card was only supposed to record from external sources

I just open up CoolEdit and played a Youtube video directly off the web and it records everything, I didn't even have to mess with the card's access board or anything either.

Then I opened up a previously recorded Youtube video in my HDD and it recorded (extracted) that audio too without problems.( the freeware Audacity also records (extracts)the audio with this method)

Thanks Marcus , I learned something new today, and this method is definitely the way to go .

PS: the only bad thing is that all Youtube videos I've seen are recorded in Mono to keep the file size small.

Edit: Man , I just thought of something else, sometimes I found MP3 music clips that don't allow you to download (My Space) I probably can record them anyways using this method I need to try this next!

This is the method Tim Tam posted in another thread. I have not tried it:

Actually you can download from Youtube.

It is slightly complicated but easy enough once you learn how.

The url in the bar at the top of your browser will say something like:
http://www.youtube.com/watch?/v=B$AZgLow04

if you insert "kiss" before "youtube"

example: http://www.kissyoutube.com/watch?/v=B$AZgLow04

and press the go button you will be taken to a new screen.

Scroll down a bit and there is a "download now" button.

Right click on this. (It has to be a RIGHT click)

and a little screen will pop up.

Left click on "Save Link As"

Another screen will pop up asking you to "Save As"

you have to insert your own file name. In the above case it the video is The O'Jays "Back Stabbers"
You can call it whatever you like but the important thing is that the

filename MUST end with .flv

example: O'Jays-Back Stabbers.flv

below the file name there is another box, "save as type". This usually says "HTML Document". Change this to "All Files".

Then click on "Save" and the video file will download to your computer.

You haven't finished just yet. You will need to download a free FLV player from the net and install that on your computer.

There is a link on the Kissyoutube page just below the "download now" button for FLV players.

There are a couple available. "FLV Player" and "VLC Media Center" are the two I use.

Now you can download Youtube vids to your heart's content.

Hope this helps.

Cheers,

This works !! Thanks, I missed that other post before.

Who could guess this about inserting 'Kiss"

I was finally able to download Nice and Slow by Jesse Green, for some reason the download plugin for Firefox is not working for me, the good thing about this plugin was that it worked with other video sites like Google Video. I don't know why is not working...

Record the audio from video by the audio recording software like FlexiMusic Wave Editor and do editing if you need and save it.
