Removing Hiss

[ajthewonderdog]

I'm sorry if there is already a similar question posted, but I couldn't find it.

I shot a video with new wireless mics, but there is a hiss that has crept into the audio track. I've tried using the denoiser, but not with much success. How can I get rid of the hiss without making the speaker sound like he is in a tube?

Thanks.

Hi AJ, Audio is one of the hardest things to clean up after the fact.
That is why we always stress getting the audio correct before recording rather than after.

You can try the Dynamic Effect, that has a limiter and gate that may help you.
You can also try to eliminate the noise with Audacity, it is a free 3rd party program.
There are instructions on removing noise with Audacity here

It is from 2005 but still applies.

If you could attach or link to a small clip of the audio it would help us better.

I'm sure you will get other suggestions from the folks here, they are always more than willing to help

I use a VHF wireless lapel mic that is notorious for background hiss. I was exporting the audio then cleaning it up with Magix Audio Cleaning Lab 10 and 11. It works wonders at removing the hiss and leaving the audio alone. I have to use my videos in a classroom and they have to use headsets. You can really hear the hiss with headsets so I had to fix it. My latest video was put together with Magix Movie edit pro and has the audio clean up tool right in the editing software which was really a blessing for me. I just cleaned up the audio right on the timeline in a couple of seconds. I've found that Elements doesn't do a good job and it has to be done with a third party software. I have Audacity but never got around to using it because I have the Magix stuff. It should work, though.

As Chuck says, Audacity should do the job, or at worst make a noticable improvement. And welcome to Muvipix.

Thanks!

I'm downloading the Magix trial now. We'll see if this works.

Okay, here's what you should do. Right click on the audio part of the clip. Any clip will do. In the menu choose audio cleaning. Then click on denoiser. Go to advanced and pick choose noise from start. Then make sure you UNclick remove camera noise only. It will not get the mic hiss out otherwise. Then use the sliders to fine tune the amount removed. It's better to keep the sliders on the lower end so as to not distrort the audio. I would use headphones to really get the sound right. If you have the project broken up into many clips you can choose to apply your settings to all clips and it will automatically apply it to everything. Good luck.
