Quote: Hi all,
I video'd my sons Wedding yesterday. When I import it into the PC and play back there is a beeping on various parts of the tape. It sounds like Morse code, obviously some sort of interference picked up by the camera. It's just loud enough to be annoying and spoils the video somewhat. Does anybody know of a way to filter this out? I'll try anything.
Thanks guys.

If your Video has MP3 audio. You might try converting the video and audio to a different format with a file converter.

MP3 is known to cause strange problems in Powerdirector.

If your video does not have MP3 audio, you may have picked up Radio Interference. In which case I have no idea how to get rid of that.
If the sound is of an exact frequency, it may be possible to filter it out in WaveEditor.

If Carl's suggestions do not work out for you, install Audacity - a free audio utility. It has EQ and isolation capabilities beyond those of the basic Cyberlink wave editor.

Thanks guys, I do have Audacity but rarely use it. More research methinks. Not sure what format the audio is. I captured it in PD11 but I think it is just one file?

Attach a small sample of the unwanted audio if possible. That may help folks analyze it.

Cheers again guys. I can get the audio into Waveditor. I have attached a small sample with the 'morse' beeping. I'm away tomorrow until Thursday buy any help would be appreciated.

The "code" is in the 3K range and can be reduced so it's much less noticeable, if not fully vanquished, through use of a notch filter in that frequency range, or perhaps a band stop/cut tool.

Is this good enough for you mrbothered1? For CL suite of tools it would require AudioDirector vs WaveEditor.

VSTs are also a consideration, though the descriptions of them are often full of audio-master gobbley gook. Both WaveEditor and AudioDirector accept VST plug-ins. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)
Nvidia GTX 960(4GB)/16GB DDR3/
Canon Vixia HV30/HF-M40/HF-M41/HF-G20/Olympus E-PL5.

Nice, Jeff. What tool did you use?

Good work Jeff...

Can't hear it at all.

As indicated, to use just CL it would require AD to my knowledge, you could also use WE but you would have to augment with free VST plug-in like dtblkfx http://rekkerd.org/dtblkfx/ . The file using WE and this free plug in attached.

mrbothered1, if suitable, I'll write-up how, it's pretty basic. If it's throughout your taping one can easily apply to all and it shouldn't do to much damage, maybe some high pitch music might be affected slightly. You would just have to try and see.

Excellent work Jeff.

Jeff, that is excellent but I've no idea how you did it. If you could give me some instructions that would be brilliant. So much better. I'm going away shortly, back tomorrow night so if I don't post right back I'm not being ignorant.
Thanks for all the input guys.

Had a very quick play with it. Got the VST in and working, seems simple enough even for me. I'll have a play with it when I get back. lovely stuff. Thanks again

mrbothered1,

The Morse code beeps you hear have roughly a frequency of 3600Hz, 4400, 7200, 11700, 14300, 15100. Some appear to be harmonics (7200=2*3600), but who cares, I don't know the source of them anyhow. You can see these highlighted with a arrow as the vertical lines in the attached pic (Freq_issue) of the dtblkfx screen capture of the Spectrogram. These are virtually constant frequency interference so what you can do is simply define some very narrow filters to remove the effect. I've defined 5 filters with dtblkfx as shown in the attached pic (Freq_issue2), for the last band to cover 14300 and 15100Hz I simply created a larger range of the frequency filter, most humans won't hear much at that freq anyhow. I simply used -inf dB filter setting but you could roll off the frequency range a given dB level if desired by changing the filter settings.

Obviously by adding the filter your removing sound at those discrete frequency ranges. This may or may not have a adverse effect on other "musical" sections of your captured event.

Jeff

Many thanks for all the help guys, my video of my Sons wedding is saved. That you can get this sort of help for free from people you will never meet is fantastic. Thanks again.
