How do I minimize breathing noises on my video? I've been adjusting the volume in the audio room but was wondering if there was a better way to do it. I have a new microphone on it's way but until then, I have to do with what I have.

In PD, the best thing I can think of is to use volume keyframes to manually drop the sound down to (or near zero) in between words, depending on whether you want to completely eliminate or just greatly reduce the unwanted breathing sounds. It might be a lot of work, but it should make a difference.

It's probably easier to do that in AudioDirector (if you have it), as you can use the plug-in effects like Noise Gate or the adjustments like wind, plossive and/or hiss removal. There's also a Noise Reduction tool I've used many times that can remove a sampled part of the spectrum without adversly affecting the rest of the clip too much. You can even save the settings as a preset and apply it to additional clips.

You can try the free Audacity app if you don't have AD and the volume keyframe suggestion doesn't work out.

You may also look into a Noise Gate effect. A Noise Gate removes sound below a certain level, so it can be used to silence sound between times when you're speaking.

It can often be quite effective -- although when overused it's "gate" closing can sound a bit abrupt.

Vocalists can use a pop filter like a panty hose stretched over a circle in between the mike and the speaker to eliminate this breathing and pop sound. A homemade windscreen can do the same thing. Google to see these DIY.
