Removing High Pitched Sound from Video

deisedude

I was recording a live webinar in work. On the recording there is a high pitched frequency sound along with the presenters audio.

Anyone know a quick, free solution to fix this issue?

You could EQ it but I'd be fairly confident this would damage the quality of the speakers voice too much. It sounds as if your recording equipment isn't up to the standard you need for this kind of work, unless the sound is in the room when recording.

It is worth switching off anything you don't need in the room. CRT televisions and computer screens are terrible for that kind of thing.

The webinar was with an external speaker so it was his recording equipment that was the issue

If there was a CRT type thing in the room, I would not place confidence in any recording system not to pick it up and would not immediately fault the presenter.

There is no practical and certainly no free way of getting rid of the sound live. If the seminar was not live then a plugin could be used but it costs money.

If the seminar is produced by the presenter completely and your involvement was just as a venue then maybe its an issue associated with the presenters setup but if what he was doing was being taken by you to then webcast, there is a possibility that your equipment is contributing by way of an unbalanced audio connection/ground loop.

If you can detail the exact equipment used by all people in list form them maybe a finger could be generally waved at something but that is really hit and miss.

Thanks for the help. It looks like it might have been a bandwidth issue in the presenters location that may have been the issue. Anyway live and learn!

Ahh, that's interesting. What did the bandwidth do?

I'm not too informed on the subject but I got an opinion from a guy we have dealt with for video production and editing and he said he has seen it quite often that if you don't have enough bandwidth for doing the webinar it can cause the high pitched effect. Now thats just his opinion so it could have been something else entirely but it might explain why it didn't show up on a test run I did a few weeks beforehand
