how to lessen "Puhh" sounds from a microphone?

[sdsumike619]

I'm capturing some audio from a minidisc via firewire to Vegas. It's a guy talking on a microphone giving a music lesson. I think the microphone was too close to his mouth because there's a lot of big "puh" sounds. Unfortunately everything is on one track, but it's mostly talking with some guitar playing throughout too. I have Vegas 7.0 - Is there anything I can do to lessen or get rid of all the big puh sounds?

There is a filter for this. I saw it once. Not too helpful, but maybe hopeful?

it's built into Vegas? Or it's VST ?

Most audio editors have a pop/click filter that might help. I believe Goldwave and Audacity does.

If you do the recordings yourself, you might buy a screen type pop filter that goes in front of the microphone to limit that in the future.

well I found out they're called plosives and I'm looking for a VST plugin to handle them but no luck so far...

"Basically the tip is the run a high - pass filter at about 1100hz to reduce the bite of the plosive" Samples to listen before and after as well as the full article is at

Hi,
Many times cutting the frequencies below 100Hz and a notch at 400 Hz will do what you are looking for especially on a voice-over, any Audio program with a Graphic or Parametric EQ should handle it. I use Steinberg WaveLab, but I think Audacity has a basic EQ. Don't go too extreme or you will end up with "telephone" voice.

Dunno if they have it in the Sony version, but when Vegas was owned by Sonic Foundry, they included a plugin called "MultiBand Dynamics". In there is a preset called "Reduce Plosives"

soopafresh, thanks, there is indeed the multiband dynamics with the plosive reduction. It kills the bass a little over all but it's better than being Puh'd to death =)

Most audio mixing desks have this facility as well. They just filter anything under 100 Hz as it comes in for exactly this purpose.

Admittedly it may take some time, depending on the length of the video and soundtrack, but you could export the sound as a WAV or Mp3 file, and import it into Audacity. Then reduce the volume at the exact point for each occasion where you want to reduce the sound. Highlight the relevant part of the waveform, click Effect, and Amplify. Drag the slider until a minus sign appears next to the number and gradually reduce it until it's at a more acceptable level. When you know exactly how much you need to do this, you can use the Repeat Last Effect command for each part of the sound track that needs reducing, to save time.
