Adjusting noise reduction settings constantly crashes camtasia. It happens not only on my mac but my windows camtasia as well. This is really annoying. Is this ever going to be fixed.

The noise reduction in Camtasia doesn't work well anyway. I've tried it and it's extremely inconsistent. You're better off to use Audacity, which is free.

I have a problem when I have to insert a voice narration to correct or add something ... I am sitting in exactly the same place, the mic is placed exactly the same yet the overall sound -- background etc is totally different.  I have to weak volume, leveling and noise reduction to try to match the sound around it.  Any recommendations???

I've made no tutorials regarding volume leveling; I never need to make that adjustment with the master controls

however, if I do need to make a short change, I just mark off a section of a clip with splits, then use the green audio line that shows on the timeline; that way, I can do quick plays across the sections

have you done noise leveling with Audacity?  maybe you could make a short how-to and share here?

lpkugelle, I get a lot of variation too, but it's mostly in my voice. The mic on the headset I use is apparently very directional, which turns out to be a huge benefit. I recently moved from working in an office where I could close the door and/or record after hours, to working at my home which is located on a busy, noisy street. I was really worried about this initially, but I discovered that the directional mic doesn't pick up the street noise, at least not at any audible level. Perhaps one could help with the issues you have.

My biggest audio issues are with volume variations and changes in the tone of my voice from session to session. I'm slowly learning to play back audio recorded in a previous session and "imitate myself".

Kayakman, I haven't actually used Audacity, although I've had it installed for a while. I've been doing much the same thing as you, using the gain setting to raise or lower the overall volume of clips and the audio points and volume line to tweak specific sections of audio clips. It works, but if there was an easy way to level the volume for an entire track, that would save me a lot of time. I guess I'll have to try this myself in Audacity.

bnystrom, @ lpkugele ...

when I use voice narration, the M4a clips are almost always twice as loud [apparent volume] as when I use Recorder; so I just use the audio line to drop the sound on that clip down to 50%; seems to work OK for the work I do; the sound level difference [Recorder vs. voice narration] seems to be a system thing?; but I don't notice any background changes?

my setup is a desk USB mic [AT2020] that sits just above my monitor, about 4' away; my environment is a 25x25 open room, paneled walls, hard furniture; so there is lots of ambiance; the mic is 3' from the wall to my left [looking at the monitor], and equidistant between the walls back and front; left wall is 22' away

the mic is very sensitive; picks up every building noise, including sounds made by hot water coursing through my heating pipes

I usually work with open windows [weather permitting], so I pick up lots of outside stuff [birds, power boats, neighbors cutting grass]; I try to dodge this stuff as much as I can, but the birds always win the day; I don't bother to try and remove them [tweat, tweat]

The mic position is likely the main difference. Mine is literally within and inch and change of my mouth. Because of it's proximity, my "voice-to-noise" ratio is very high, to the point that background noise isn't audible at any reasonable listening level. At a minimum, I would suggest repositioning the mic on a desktop (or hanging) within 12" and directly in front of you. That should make a huge difference.

If you need to reduce the overall volume levels of your voice recordings, you can do that by changing the record level in Windows if there is no volume level adjustment on your mic.

We do indeed have a known crashing issue here, at least on the Windows side, and we are working on the fix right now. While I don't have a specific date for when it will get into a maintenance update, it is on the way.
