I shot a video of a live concert which of course was incredibly loud, so the problem with the recording (besides me not using a better external mic), is that when the sound is too loud or there is too much bass, the audio becomes distorted....now I am pretty well versed with computers so I was trying to mess around with ffdshow filters and also with Adobe Audition, but I am not the best with sound stuff....I tried normalizing the file and also lowering the amplitude but it doesn't seem to help. I also tried messing with the Equalizer, but to no avail. Here is a 20Mbyte sound clip (about 2 mins in length)...Please check it out and let me know if it's fixable! Link

Thanks so much!

Ummm, I don't know if there is a whole lot you can do with that. It's clipped all to hell and back the way it went down onto the tape. you may be able to eq it a little for freq. response, but I doubt you'll ever get it to sound very clean.

Good Luck
 
With digital clipping, sometimes a high pass filter will help (just help)
 
Yeah, there's nothing you can really do with that much distortion. The bass rumbling when the rest of the band comes in killed all hope of that.

I just don't understand the necessity of cranking stuff to unbelieveable levels in live shows... and I'm in a rock band myself.
 
Does anyone have any "cheap" suggestions of an external mic to use for really loud sources so I can avoid this on future occasions?

the cheapest way is using the gain knob properly. you need to plug your mic into something that will allow you to control the level going to tape.

I don't know how cheap this would be but I have a cheap Sony DVD92 Handicam. 400 bucks new but that's been many years ago. Look on ebay.The audio I get from this camera is amazing. We were playing a show outside at a bike rally and really had it cranked up. My somewhat tipsy, wife had the camera within 1 foot of out mains cranking at arounds 1700 to 2000 watts and it came out crystal clear, great bass response, mids, highs across the board.

Since I can only get 15 minutes to a disk, I had my brother bring his Sony HDD1 hi Def Hard drive cam to our show last weekend. Sitting about 30ft away from the stage and we had our lecvels pulled way down because of the room acoustics. Keep in mind his camera is Dobly 7.1 SS and cost him a whopping 1600 buck. It all came out sounding like crap. It's pretty good until the bass comes in and then it goes to hell.

Evidently my cheap little cam has some built in compression to keep sound levels down. We practice in a room that's 16 x 28 and it's loud in there. We play at local show levels when we practice. I can take my camera in there, hook it into my computer mixing program and record just the audio and it comes out great. A little EQing and it's good to go.

It's easy to bring a weak signal up. Pulling the distortion out so it usable. It can probably be done at some high end recording studio but "IF" they can do it, it'll cost you. Count on that.

My video from the last show is unusable because of the audio, so we're gonna record new tracks for the songs and replace the distorted tracks on the video.

I kind of hope he has figured it out in the last 5 years.


This gets my vote for "Necro-Post of the Week"!
