Over amplified, any suggestions on how to fix it?

[thecoalman]

Just got a new Canon GL2, still learning how to use it. Anyhow I just recorded my buddy's playing and used the auto mic (last time I'll make this this mistake). It's over amplified, not sure if that's the correct term as I'm a complete newb when it come to audio. Anyhow the audio is breaking up the speakers even at a low volume, I was able to adjust it to get some decent audio out of it but still not great.

I was hoping maybe someone could offer some suggestions ot tips. I just downloaded the soundforge demo but I think that's a little too advanced for my needs (and expensive), I think I'm going to try the goldwave demo. Here's a link to an example. 900k file, it's converted from the raw capture in MSP. www.nepadigital.com/40lbhead/headexample.mpa

Use the SOUNDFORGE paragraphic filter on my site. Look for the preset (in the download file) that I call "REMOVE HARSH HIGH CLIPPING".

If the tone is lowered too much, use the HIGH RESTORE "I" filter.

I bet it'll work.

edit: Having just looked at your file, that may be a tad too much. But I'm sure some of the filters I made will work. That does not sound hard to fix at all.

Thx LS, I have it sounding O.K.... Still getting a little bit of speaker breakup. Converting it seems to make it better? Sounds better on DVD too? Sounds horrendous with direct connection from cam to TV......

Guess, I'll just have to sart experimenting, not a huge deal. It was just to test it to find problems such as this. Too bad the audio sucks as the video is great.

Thanks for the advice.

No dice.... Still blowing up the speakers. Here's a PCM wave file if you want to check it out.

www.nepadigital.com/temp/example2.wav 33mb .... don't be shy it's a fast server.

Another question, is this actually missing sound? Is that what it is? Like I said this was just a test run so it really doesn't matter, just sucks cause the video came out good and it's nearly 3 hours of footage. LOL went from bad video w/ good audio to good video with bad audio.. Oh well live and learn.

This may sound strange but I demux the audio with TMPGEnc->convert MP2 to MP3(320kbps CBR)->use MP3Gain to normalize->use CDex to convert MP3 to MP2->multiplex.
I have used this method a couple times with early captures that were clipping.

Actually it doesn't sound strange at all, after I convert to AC3 and burn to DVD it helps a little. If you listen to the first clip I posted and compare it to the second you can hear a signifigant difference. Nothings been changed but the format. Any good links for learning about audio? Specifically about clipping.

It's best to use a VU meter when capturing analog and keep the dB below -2(80%):

The cam has the meters on it, the reason it's screwed is I used the auto level function. The audio is fine before the band comes on. You can manually adjust it. Apparently the auto function doesn't work well for very loud situtations like this.

It's the bass drum that's overdriving the signal.

Check out the bump between 40 and 89 Hz.
