Help with an audio file - vows from a wedding.

Question

Evening all,
My wife and I filmed a wedding yesterday and our wireless mic which was hooked up to the groom's lapel decided to cut out literally seconds before he spoke his vows. When I got the mic back from him, everything was soaked, literally dripping and also extremely warm. He couldnt explain why it was so wet, sweat he said. Unfortunately we lost our crystal clear version of the vows and have to work with a secondary version. We had two other cameras going as well as our primary. My wife had a Rode Shotgun mic on her camera and picked up the groom and brides vows, but you can hear the constant hum of the mic. I have dumped the file onto FileSnack and have provided the link to check out. Is there anything we can do to make this sound better, as well as perhaps bring up the audio from the bride and groom.

Answer 1

I've had a little play and Steve's right that there's no miracles to be had.  However, have a play with Audition's EQ section and try taking down the level between 3k and 4k.  That gives you a slightly boxy sounding voice but also cuts some of the clicky sound--it's a balancing act to decide how much EQ you want.  FYI, I tried both the 31 band graphic with 3.2k pulled down a lot and 4k somewhat down.  I also played with the parametric with a fairly steep Q centred around 3.7k.  I think the parametric will eventually do the better job but ran out of time when a paying job turned up.
A bit of high and low cut would probably help as well and maybe some slight boost in the 250-800 range to help the intelligibility.
Anyhow, hope this helps.
Now, a tip for "next time".  Sweat outs are common in theatre where we often hide mics in the hairline.  If if have any inkling of an impending problem, spray a small section of an old pair of ladies stockings or panty hose with Scotchguard, cut out a small circle and stretch it over the mic capsule--a rubber band can hold it tight.  Similarly, putting the TX pack in an unlubricated condom or a ziplock bag with only then antenna peaking out protects that end.
