I record my shows on a mini DV recorder (video and audio). Sometimes
when I play them back (after burning to a dvd) the audio sounds buzzy
on peak sounds. Sort of like if you turned the sound way up on a
cheap old television and the plastic TV case vibrated, or a little
fuzzy like turning up an old radio so loud it distorted. And the bass
is also boomy, though my voice itself isn't that low.
Here's a 33 second clip as an example: http://brainchampagne.com/Info/Audio.wma
(note that after the first sentence there's a bit of silence, then it
continues; the silence is because I took this from a video where I put
in titles, not because of a pause in the actual show)
It doesn't sound distorted on my computer but my computer volume
doesn't go that loud and perhaps the frequency response of my
monitor's speakers is bad. But when I play the original tape through
my tv I can hear the distortion there.
So-- any ideas about:
1. What's causing it?
2. What I can do to prevent it?
3. How can I get rid of it on existing recordings? (perhaps notch
out a certain band of frequencies? run some sort of software?)
Thanks so much!

Shawn, mini DV cameras have certain characteristics to save the na�ve user
from disaster:
1. Automatic volume control
2. Limiting to prevent digital "overs."
It sounds as if the audio input to the camera is too hot, forcing the above
circuits to work continuously. They are not designed for that. They become
audible if continuously activated. If your camera has a mike gain control,
back it off. If it doesn't, keep a greater distance between you and the
microphone.
A further indication of the excessive gain is the very audible hum when you
are not speaking. The camera automatic volume control is cranking the gain
all the way up during the quiet periods. These problems are difficult or
impossible to avoid with cheap equipment. To get decent audio, you should
use a "prosumer" camera; these start above $1K, and have manually adjustable
gain.

I'll add that good quality brick wall limiter such as the Aphex 720
Dominator goes a log to prevent overloads when used for such critical
recordings. These are used in broadcast all the time for just such
purposes. Whenever I provide cameras a feed from a live performance,
the 720 is the last thing in the chain before it hits the camera (or
any other type of recording device). You can find them used on Ebay
often for less then $400. New they cost well over $1000.

It sounds like shit all over.
How are you setting your levels? It sounds like crappy camera audio, not
like you're feeding a separate deck. (Which I assume is meant by
"recorder"). Are you having some sort of compressor/limiter/AGC between your
mic and mixer and the camera? What mic are you using anyway?
And so on.

I used a six year old Canon ZR60 mini-dv camera with its built-in
microphone. Normally it sounds decent but I think the problem
resulted from the camera being too close to the PA speakers.
This camera has only two settings for audio that are changeable. 12
or 16 bit recording (they recommend 16 bit for better quality and
that's what I used) and turning the windscreen on or off (it was
probably off as this was an indoor recording).
I have a newer camera that doesn't seem to have these difficulties, or
at least so far it hasn't. I now use this older camera (with a wide-
angle lens) next to the stage, pointed at the audience. I hope that
will result in cleaner audio since it's no longer pointed at the
speakers but at the audience itself. And that if I have to, I can mix
this audio with the video from the other camera (usually at the back
of the room, pointed at the stage).
But I really want to use this clip in a promo video I'm doing. Does
anybody have a suggestion for how to cut out the buzziness on peaks?
thanks,

Your request is very common and sad. There really is no way to fix it.
Bob Morein

The constant hum can be minimized by tools in the noise reduction section of
Adobe Audition.
You capture a sample of the noise by itself then apply it to the entire
track.
The popping noised can be minimized by the pop/click eliminator tool.
EQ / parametric EQ can be used to improve the overall recording.
In the FFT section a preset called "kill the subharmonics" or the one
called "kill the mic rumble" can reduce LF rumble thereby making the
recording suitable for playback on typical small speakers.
In cases of audio clipping the "clip restoration" can be used to improve the
audio somewhat.
The best and easiest method is to record clean audio in the first place :)
Now you know why Hollywood uses separate sound equipment...
If you want to record decent audio in your show, you're going to have to buy an
audio recorder, maybe with mixing capabilities to use 2 mics, one for you and
one for the audience.
Typically, you can use your main mic for both PA reinforcement and audio
recording.
You can use your computer video editor to re-sync the sound later. Most programs
can do that. Some equipment can sync digitally to time code, but that's big
bucks, you don't really need it.
As for fixing what you have now? Forgetaboutit! Cameras usually have auto-level
and compression and also pick up camera motor noise... you will never fix it...
Did you ever try an external mic? That's the least you could do...
Just two rules of thumb before I have to go to work:
- The best place to put a camera is often the worst place to put a
microphone.
- Recording audio onto a device that does not at least feature 2 XLR inputs
is usually a pointless exercise.
As far as cleaning up your audio goes: if you fancy playing around with
restauration software, go for it. But it would probably be quicker, easier,
less painful, more cost-effective to just kick that audio into the bin and
redo it. Properly this time.

He's a one man band. I don't see separate sound as feasible. This would do

Bollocks. He's using a PA. Which means he's got a vocal mic inches from his
mouth. Put up another mic as audience mic, feed the camera from an aux of
the PA mixer, and Bob's your uncle.
Does need a cam with sound inputs though... Or record to DAT or whatever,
and sync in post.

I still don't see what is "not feasible" in this scenario.
A camera with a pair of XLR inputs will have manual gain. As will a DAT
recorder, or any other recorder with a pair of XLR inputs. Levels need to be
set before the show. Whoever sets the levels needs to know what he's doing.
Sounds all feasible to me.

Was thinking the same. THere's a pa involved somewhere, a
camera with decent audio inputs fed from an aux on the mixer and he's good to go.

True, and even with the alc etc. if you set levels
conservatively you should never trigger that junk, least
that's the theory.

Cameras differ. Some can take a lot more input into the first amplifier before
the ALC. I have also used and external mic with attenuation of at least 10 dB.
15 to 20 dB should make most not overload. Thats probably strickly DIY.

First of all, thanks so much to everyone for the help! I didn't know
that Adobe Audition existed (and it has a free 30 day trial). It
works much better than other Adobe software I've used (Premiere
Elements didn't work on my machine even though it far exceeds the
required specs, and Photoshop Elements works but it's really, really
slow to load and not very intuitive to use). So I got rid of much of
the boominess via reducing the bass (I have other software that'd do
this but Audition seems to work better and their noise reduction is
better also). Of course my voice sounds much higher-pitched after
doing this but it's still okay for my purposes.
I think I hear the distortion more on my TV than on my computer
because my TV probably equalizes for a false bass and that exaggerates
the distortion.
I can't do anything about the AGC on my existing camera but I now have
a second camera which seems to work better, and I use the old camera
to point at the audience so at least the speakers aren't blasting
directly at it. The newer camera, at least so far, sounds better.
Yes, clubs have sound boards. They also usually have policies against
letting anyone plug into them because random people who don't know
what they're doing can cause damage or at least screw things up.
Synching the audio and video's not easy and getting it close enough so
that it doesn't look lip-synched takes a lot of trial and error, but
fortunately I won't have to do it that often.
The popping noise actually somehow got introduced later in the
process-- I went back to the original audio/video file and it's not
there. I am now working off that, so the popping's gone.
I looked into a wireless external mike to place on/near the stage, but
what might work with my consumer camera appeared to be very
expensive. It may be easier to buy a better camera that's made to
take a wireless mike, but that's a bulky thing to carry around and I'm
not all that comfortable leaving $1500 worth of equipment sitting at
the back of a room when I'm on stage. It's easily knocked over (or
taken).
As far as just scrapping the clips that have problems-- not easy to
do-- there are particular clips that I really want to use, and they're
not reproduceable in any other random show because every audience is
different.
I've gotten it mostly cleaned up, and the finished product will be
here in about a week:

I did a show with Carrot Top a few years ago. We had 14 loaders to
unload his semi. With rock shows, we usually had 4.

When I was in college (and for 10 years afterward) I was on the rowing
team. I was always a bit jealous of the runners and swimmers, since
they just had to show up. We had to transport huge boats, oars, etc.
Then later when I became a comic I realized it was reversed-- I just
had to show up and talk, but musicians had to carry stuff.
I'm sometimes at Gotham Comedy Club in NY. Also in LA from time to
time-- was just there, and hope to be back in March. Bob, I'll try to
let you know where/when I'm playing in LA, I assume it's okay to call
the number you posted.

Let me know if you come to Pittsburgh; the email attached to my name is
valid. Comedy is tough. You have no one else to save you on a bad night
or with a tough crowd. I used to book a club, & I booked Mark Eddie for
a St Patrick's day show - he had killed on previous shows (rock venue -
musical comedy). His most memorable show for all the wrong reasons. He
just couldn't connect with the drunked frat-boy crowd that day; the
jokes went over their drunken heads.
On the flip side, I opened for Steve Martin back in the mid-to-late
'70's. As a musician, I'd naver open for a comedian again. "Get off the
stage. WE WANT STEVE MARTIN!" Nightmare..... Steve Martin was just
starting out then. BTW, he was a very nice, humble guy, driving himself
all over the country in a rental car.
I could tell you some more interesting comedy stories, but I'd probably
embarrass myself....

I worked at two different clubs through the 80s and 90s that had
regular comedy nights. Just about any up and coming comic from
the NYC and Boston area worked those clubs. Many went on to
do quite well in TV and movies.
Rock musicians have nothing on comics when it comes to raising
hell or indulging. At least, that's how it was in those days.
As far as Gallagher and Carrott Top go....
Sure, they have more gear than most comedians. But, most comedians
are funnier than they are, and don't need gimmicks.
At one time, both of them were managed by Gary Propper. Former
East Coast surfing star from Florida who was one of the creators of
Teenage Mutant Ninja Turtles. Some pedigree, eh?

I only saw Carrot Top on TV before the show I worked, & I didn't expect
much. But he did a great show. Much of his comedy couldn't be put on
broadcast TV. His props & special FX were impressive. His ad-lib stuff
was smart & had the crowd going. It was one of the best comedy shows
I've done. Honestly...
- Denny
Maybe I should have mentioned that he had more Pyrotechnics than many
glam-bands. Lasers.... I could go on-and-on-and-on. He had a sound man,
a light man, & a special-FX/sound-FX man. Great show.

Not at all. Gary Propper was the first person from the East Coast
to make a name for himself in the world of competitive surfing.
He was signed by Hobie surfboards around 1967, and lent his
name to his own "signature" model surfboard. At that time, Hobie
was essentially the #1 surfboard brand, world wide. The board that
bore Propper's name became the largest selling 'model' of the 60s.
After he retired from surfing competition he went on to become a
concert promoter, which led to his association with Gallagher and
Carrott Top. He made a nice bundle off the Mutant Ninja Turles, too.
Hobie Surfboards ad from 1967, featuring Propper and his model.
http://i48.tinypic.com/95pset.jpg
Your skepticism might be based on the fact he's from Florida?
That would be misplaced. The person who is considered to be the
top professional surfer in the world, Kelly Slater, is also from FLA.
He's from the same area as Propper, in fact. He's a nine time world
champion, and is probably the highest paid pro surfer, ever. I believe
his major sponsor contract was a five year deal totaling $10 million.
Just Google the name Kelly Slater, if you care to.
So, whatever the reason you took it as a "joke", it was based in fact.
--
Steve <snip> McQ
While most of that page is accurate, Propper was not the
first guy to have a surfboard marketed with his name on it.
He was the first East Coaster.
In the industry, that is called a "signature" model. The first
person was Phil Edwards, another member of the Hobie
team in the 60s. The Edwards model debuted in 1964.
Another distinction is that Edwards actually hand shaped
many of the boards that bore his name. Propper did not.
Propper was involved in the design stages, but had no
hands-on experience building surfboards.
And, yes...anyone who worked major gigs in the Cocoa Beach
area during the 80s probably came in contact with Propper's
organization.

> So, whatever the reason you took it as a "joke", it was based in fact.
As a journalist, I found pinning him to Florida editorially and juxtaposing
that with his surfing prowess very amusing. The sentence would not hold the
humor aspect if Florida had been absent.
I think you're making unfounded assumptions. As a journalist,
you should know that's a bad way to approach a subject.
But, I can understand where your ideas may stem from. The
general public is prone to making many wrong assumptions
about surfing.
Have you ever spent much time on the central coast of Florida?
