Audio Problem
Hi shooters everywhere.
I have recorded a short interview sequence where the audio level on the speech is fine however, in the background, there is a lot of unwanted noise caused by the wind blowing through the trees. Does anyone have any idea how I can eliminate this noise.
It was recorded as a 16 bit stereo track and I am using FCP3 on a G4
Many regards to all.

Hmm, sounds like a job for the Parametric EQ (in FCP audio filters), but in all honesty this sounds like a very tough nut to crack. Any chance you can re-record it? Find the freqs of the voices and pump them up a notch or two while lowering the overall volume of the clip. Just thinking out loud,

David Phillips February 15th, 2002 03:48 PM

Thanks Chris, I'll give that one a try.
No, can't re-record that's too easy.

Ken Tanaka February 15th, 2002 04:14 PM

You might also have some luck massaging the sound tracks with Peak DV (which is supplied free with FCP3). It's a dedicated sound crafting app and has a few more facilities than the filter provides. I agree with Chris, however, that this will be a tough problem to fix. I'd bet that the noise comes in waves (with gusts off wind) so any intermitent mitigation might be unfortunately noticeable unless it's applied to the whole track uniformly.

Good luck.

To balance or not to balance...
that IS the question...

I'm going to try and and solve the balanced / unbalanced xlr cable run noise quandry once and for all.. I guess I need to know before I actually have to do this at a gig.

I have a 100' x 16 channel audio snake. I'm going to hook up my AT835b condenser to my MA300 on the GL2 at 100' then by daisy chaining the input to output I'll do 200', 300', to 1000' etc. and record the results, Then I'll do the same test with a dynamic mic.

Let me know if you're interested in the results and I'll post the audio clips for everyone's review. Maybe that will clear the air on just exactly what is possible with an unbalanced connection.

One last note: the folks that record symphonic music try not to use transformer balancing, the most common method by far (and the one used in virtually EVERY DV XLR circuit), because it imparts too much of it's own flavor to the signal. They tend to use circuits that are transformerless.

Check out this link for some in depth info on mic pre design & balancing methods from Millenia Media. If you think you are concerned about audio, then you must read this.

I would be very interested in the results. Thanks Mark!

Gitzo Fishpole and Cable Feeding
I recently picked up a Gitzo G557 fishpole. One of the features of this pole is that though it doesn't come fed with cable, it has 'port holes' for threading the cable yourself.

However, these holes obviously don't accomodate the connectors (the holes aren't wide enough for any XLR connector that I've ever seen). So my question is, what's the point of having the holes in this thing? Is it for expert techs out there who perhaps can feed the cable and then fashion their own connectors?

Anyone fed a cable through a Gitzo before?

Jeff Donald December 24th, 2002 12:47 PM

You will need to soldier your own ends. Their are different types of XLR connectors. I have several mics that require what is described as mini XLR connectors.

All Things Audio -- topics from 2002 thru 2004
Just picked myself up a Tivoli PAL speaker as I had seen it mentioned on a location audio mixer website. I occasionally need amplified playback on location for one reason or another, and I had never seen a small 12v power speaker that sounded decent for the right price.

The PAL is a gorgeous little unit that has an integrated FM tuner (great quality, and the manual knob is delightfully old-school). It accepts a stereo mini-plug input, has a 3 hr NiMH rechargeable pack inside and sounds unbelievably good. You'll wonder how they got this sort of bass response out of such a small unit, but then again it was designed by audio wiz Henry Kloss. It's rubberized for location use, it's exceptionally solidly built, and comes in a bunch of cool colors. And priced right at $129! Ya gotta love the pricing on consumer-level gear.

Check out:

New Minimount design
I bought a mini-mount + universal shoe carriage + sleeve for the ME66 less than a month ago.

Today I went on their website and discovered a complete new design for the minimount !!!

What happened to the previous one (the one I just got) ?

Is there any issue with the older one ?

I suspect this one to be more cost effective as it doesn't require a sleeve to adapt to the different mics.
[correction] It's probably more cost effective but not cheaper ... went up to $189 !!!

Any information/comparisons for this new mount are welcome because I would feel bad for my very recent purchase if this new design is correcting major issues from the first gen.


Dany Nativel February 5th, 2003 09:10 PM

I'm suprised that nobody jumped on my post to give me a feedback.

There must be somebody that bought the new design and owned the old one before.

Any comments are welcome !

Chris Hurd February 5th, 2003 10:29 PM

I have talked to Thomas Dyer at LWS about their new design, but have not seen it yet. We do need to get a review or comparison up on dvinfo.net -- I'll put this on my agenda.

Bluetooth microphone???
I know there are a few headsets out there for cell phones, but is anyone developing a high quality microphone or microphone adapter for BlueTooth transmission?

I have heard Bluetooth is less susceptible to interference plus a notebook USB receiver unit is remarkably cheap

Neil Fisher February 24th, 2003 04:44 PM

it's low power so you wouldn't get high quality, and its limited to 30ft.

check out http://www.bluetooth.com and do a search, it's a great web site.

Mic for Sony MZ-N707
I just got a new Sony minidisk for a backup sound unit. My question is what microphone are you all using? Mono, stereo, mono/stereo adapter etc. I know that it has a stereo mic input, but, someone said I could use a mono mic with a stereo/mono adapter and it would input over both channels.
