Strange high pitch electrical noise

Hi all, I'm hoping someone can help with this issue. When recording narration, at certain high pitch tones I get this strange electrical warping sound, see here for example: https://www.dropbox.com/s/aek4zscmd5ubu41/Ringing testing.wav?dl=0

I'm using a large diaphragm condenser mic with phantom power supply, into a desktop PC with a Sound Blaster Recon 3D sound card which has an integrated preamp. The weird sound isn't present when I listen through the Sound Blaster app but it does appear when using Adobe Audition or the Windows Record app.

If anyone has any ideas why this might be I would be very grateful!

Thanks, Simon
 
"electrical warping "? The only thing I hear is you overdriving the diaphragm of the mic. Back off from it and use a pop filter.
 
Yea I tried backing off and it's still there, I'm also using a pop shield.

p.s. I'm referring to the high pitch ringing tinny sound
 
Check your file - all I hear is a thump (presumably as you turn something on), then you going 'hoooo'. Just popped it into EQ, nothing showing over 1KHz.
 
A) Posting a 5-second clip doesn't help.

2) What you may be hearing is a resonant frequency of your room when you are "ooooo"-ing at that pitch.

C) But that is impossible to tell from a 5-second clip with you going "oooooo" above the noise floor of the room and mic.

Are you monitoring through headphones or speakers when doing takes?

What I hear sounds like mic-handling noise at the beginning of the clip followed by possible feedback.
 
The noise must be a replay artefact, nothing on the RMA spectrum.

BTW I could not open the downloaded "wav"? Rmark said it was an unknown format. I had to open it in Samplitude Silver then export as 16bit 44.1kHz stereo.

Dave.

That sounds terrible. I don't know what it is. I'd start by (borrow, buy, something) a "real" interface -- Whenever I see "SoundBlaster" I think of something that blasts sound.

It's much lower in pitch than VDO whine -- Even on the room noise before the Ooooo I can hear something weird going on that shouldn't be there... Sounds like a mult of some sort - probably not related to the whine, but something else that shouldn't be there.

They're on ecc83's post above -- I can't confirm 2.5k (might've been a momentary spike), but there's strong nasties at 3.7 & 4.1 and their 2x multiples.
 
Don't know what reminded me, but I recall back in the day having to go into the advanced Windows Mixer settings and mute absolutely everything other than what I was using if I wanted anything near "clean" -- Not sure if that will apply to this, but it's worth a shot if you haven't tried it.
