Audio Clean Up Help Request

[ihatemybike]

My daughter is beginning to put videos on YouTube, but her camera's built in mic seems to be a bit quite. I have to crank all available volume controls while watching her vids.

Here's an example.


I'd like to increase the volume and kill some of the white noise. She didn't keep the original file from her camera so I'll be starting with the flv file from YT.

Anyone have good tips / instructions?

Get a good external mic. The built in ones are garbage.

I agree on the mic thing. Really need to change her recording set up, right now she's using a Samsung SL420 digital camera. Upgrades will happen as soon as I can. Still I'd like to try to clean up what she's already recorded as much as I can.

Something might be doable with a proper setup, very much outside my area of expertise but one of the guys from POC and I were discussing audio remixing and he's a pro, he might not venture to this part of the forum so shoot him an email and he should be able to offer some assistance.

Unfortunately there's not much you're going to be able to do with this. You can suppress the white noise but in so doing, you will make the whole thing sound robotised and low-bandwidth.

Best thing you can do is to get a Shure SM58 microphone, which are great for vocals, and run it through a mixer into a laptop whilst filming the singing. Ideally you would need an external soundcard if your laptop does not have a line-in port (the microphone port on your laptop is amped). Then put the two together, using a video editing programme such as Adobe Premiere Pro (or I think Apples have a built in programme).

HTH,

Here's what I did:

To record my sister we used either a JVC Everio HD or SD-card recording cam. These delivered quite reasonable audio files as is (Here it is an example in unfettled form: Mendelssohn Maienlied)

I used avidemux-qt (available for Linux and Windows) to save the sound track separate before cutting the video. Then I used an audio editor to reduce noise a bit. Audacity would work, but not as well as a program called gwc under Linux (see: http://gwc.sourceforge.net/). Here I was able to draw a sample of the noise and delete it from the remaining track - but not fully, 60-70% delivered good results. These are good enough to be used on an audio CD - not studio quality, but quite nice to listen too and definatly not embarrasing.
