Hey guys,

Are there any Sound specialists in the house today?

I have a blip in a soundfile loop that I cannot seem to get rid of.. I have re-edited it in Audacity quite a few times.. Doesnt want to go away. Any thoughts or advice?

Depending on the "blip" it should show up as a large spike on your audio graph. Isolating the specific area and running a noise cancellation over it may help.

It also could be a split second blank at the beginning or end of your audio file then when it gets looped it comes out as a blip.

Might want to contact Sonic over at our forums he is a sound engineer.
 
You may need to use what I like to call a frequency dropper. Although not a technical or appropriate term, essentially what you would be doing is eliminating a set frequency from the audio file. Unfortunately, this may require mixing "other" audio from the sample to fix this particular part... as it isn't exactly like you see in the CSI episodes.
 
Thanks Tim,

I'll check that.

I went into extreme zoom and matched the break points in the harmonic. That reduced it quite a bit, but its definately still there.

Hey Cody,

Roger that man. Sounds intense! lol.. :kilroy:

I wonder if Audacity is just not able to make a loop? or perhaps the delicacy of the cut points is far more important then I thought..

I have never worked with Audacity, and I am not at my work computer, so I can't directly help you. I do know however how I would fix it in Vegas using the in program audio editing tools. When I worked for Exciting Simulations on SSM07, I spent days looking at hundreds of audio files. It was work that I may never want to do again on that scale, but I learned a lot.
 
Audacity is a freeware tool Bill and as such is 'missing' some features that pro or semi-pro applications have.

I have some semi-pro software here and would be more than happy to take a look at that sound file for you if you like.

BTW I do have some experience working with audio files as I used to run a College recording studio (16 track tape) and taught professional sound recording techniques at College level in the UK and I also helped out at a buddy's pro 24 track (tape) studio and was credited on at least 4 commercially released rock CDs as the Assistant Engineer.
 
I do a little with sound... :d (it's what I do for a living...)

I'd be happy to take a look if you're still stuck. Too much filtering can cause odd phase shifts and what-not so one has to chose the order of operations carefully. There are lots of tricks that can be done, provided the sound is clean to begin with.
