Anyone Test the Audio on the PMW-EX1 Yet?
on Nov 16, 2007 at 6:53:49 am

Has anyone verified Sony's claim of +/-3dB 20-20KHz for the audio on the XDCam EX yet?

There's an easy to use RightMark Audio Analyzer program at: http://www.rightmark.org/ and the process takes 5 minutes to complete, including hookup of cabling.

I'm sitting on a purchase order for four of these cameras and the only thing holding me back is the question mark about the audio. Hopefully someone has got one of these babies in their steely paws and is able to confirm my request.

Thanks in advance!

Take care,

Mark & Mary Ann Weiss

Can you elaborate on that just a bit for us non-audio types?

I want to make sure we're not buying a pig in a poke, like we did with the HVR-V1U last spring. Quoted specs were 20-20KHz in the B&H web site, but the camera actually tested to be 1,200-20,000Hz actual.

Sony is claiming the same response for the EX1, but qualifying it with +/-3dB. I asked Simon Wyndham about it, but he has yet to get around to testing it. I figure by now, with several of these in the hands of owners in Europe, someone could run the RightMark test (a free download) and verify Sony's claims.

Mark

I am not an audio tech and I could use a paragraph explaining the technical side of your concern. Pretty please...?

Certainly, Steve.
Although I am not sure it will be easy to condense it all to one paragraph. But here goes:

We human beings have the most amazing set of senses, with hearing that enables us to easily perceive sounds ranging from 20 cycles per second to 20,000 cycles per second. But human hearing is not equal at all frequencies. Fletcher and Munsen did scientific studies on the sensitivity of hearing over the 20-20,000cps range more than half a century ago. Their findings characterizing the

Sorry I didn't reply sooner. I'm going to have to read this several times to digest it all but you've answered several questions that have been rattling around in my head for some time. Thanks for taking the time to give all of us a primer in the world of sound.

Thanks for your feedback, Steve.
I'm home recuperating (was released from the hospital Wednesday night) from a traffic accident where someone rear-ended me at a traffic light. I have some lower back injuries and have limited mobility for a while, so I'll be around the computer more than usual this week.

Take care,

Why not email DV dot Com's audio guru Jay Rose? He's tested a ton of cameras over the years and would probably be happy to share his thoughts on the EX.

Sony claim uncompressed 48k audio so it should be good going line in.

However why not record seperate sound if sound quality is a major issue?

Compression isn't the issue at stake here. What I'm trying to find out is whether or not Sony put a big high pass filter in the audio system, that's non-defeatable, like the V1U.

When audio is important, we use separate recording system, but for run & gun situations, it's rather cumbersome. And it's a major headache to deal with it in post. However, if XDCam EX is as good as Sony claims, it should be quite adequate for informal shoots where pristine audio is not the main focus. Situations like parades, where you have to move about on the street precludes having a MotU 896, 12 volt lead acid battery, inverter, laptop computer in a wagon.

Take care,

I dunno. As long as the wagon was red and had the words "Radio Tot" on the side I think I'd do it :)

Thanks for that Mark!

Very informative. You should write a book if you haven't already.

Looking forward to hearing what the results of the test are.

Thanks Joe. However, there are quite a few people in the video community who are award-winning pros who feel that I don't know anything about audio and even LESS about video, so I don't know that it would sell. :-)
But some folks have been telling me for years that I should write a book and distill some of my knowledge into some published format. With book sales slumping and e-books being cheap or pirated easily, I'm not so sure that it would be worth my while--writing a book is a major undertaking.
But I've not ruled it out.

Take care,
