capture audio only

Is there any way to capture just the audio? I sometimes like to make a music CD out of my kids music and band concerts. I usually capture and then cut the video track, but it would save hard disk space (I think) if I captured just the audio. Also, any recommendations of reducing some of the unwanted noise that comes with recording live? I've played with some of the effects in Vegas, but I'm not accomplishing much. Thanks

Noise = Noise Reduction. Costs some $$, but you'll wonder how you got along without it.

As far as the capture, I don't think you can just capture audio (or video for that matter). If file size is an issue, render the file as a wave and ditch the original.

To record audio only you need to patch the camera audio outs to your sound card. Otherwise, as Jessariah says, capture both, render as wav and throw the avi away.

Live noise is best reduced by careful placement of mics and setting of levels. You really need an audio mixer and maybe four or more mics.

Take a look at Scenalyzer Live. It has an option to capture audio only over firewire.

I've done audio several times in vegas (infact, I don't use Screenblast Soundforge anymore, Vegas is THAT GOOD!)

Plug your audio line into your computers line in port.

Open Vegas. Open your volume control.

In Volume control, go to the properties option and select RECORD properties. Make sure LINE IN is selected.

In Vgeas, make a new audio track. Hit the record button on the audio track. You will now see an audio level meter. That what is comming in over your line in jack.

Now, hit the record button under the timeline, and it will start recording. You will see the waveform created as you record, and can even adjust the volume while recording!

Awsome!

I presume though that the idea here is to accomplish a digital transfer rather than an analog re-recording.

My assumption too, Kelly.

So I can render my captured video/sound as a .wav file, then bring that .wav file into Vegas, apply any changes, effects, track markers, save as a .veg file, and then render again as a .wav file (finished project). Is that right?
I assume by noise reduction you mean Sony's Noise Reduction 2.0. So this will work with Vegas and not just Sound Forge? One person responded that they thought this program worked really well. Anyone else who has used it, I'd appreciate your input. Thanks

Yes, that is correct.

There aren't many pieces of software that i would call miraculous, but SONY's Noise Reduction 2.0 would be one of them. :)

Okay, I may give Noise Reduction a try. It's offered through a company where I purchased Vegas and they have substantial savings for educators. I can get it for $69, so it may be worth a try. Thanks for your input.

I assumed the same thing, but it didn't make any sence to me. He wouldn't get a higher quality then if he captured the audio analog vs digital (i assume he's comming from a mic on the camera). Plus, he'd have more control of the audio with doing it analog (can control volume, se if it clips, etc).

I was also thinking he was recording onto his comp at the live event (you know, mic infront of speaker, into a small mixer, into line in).
