Hi there everyone,
Regardless of the type of content you produce when creating your course the one thing that is always important is high quality audio. So the question is what settings do you use before hand to get the best results from your audio. I will start with my setup-
Microphone: Blue Yeti (USB Microphone)
Editing Software: Audacity or Adobe Audition (Mainly Audacity)
I often find that getting the gain levels just right for the environment you work in is one of the most important things you can do when setting your system up as it defines how much background noise you can potentially pick up.
Microphone: Focusrite Scarlett Solo 2nd Generation (Condenser Mic)
Editing Software: Only Camtasia, actually.
I use a Shure SM35.
Gain set to around 80% on the audio interface.
Channel set to mono. Gain set to 100%. No noise reduction settings.
It's by far the best microphone I've used for recording in bulk with minimal sound editing!
Sennheiser MKE600 for me, connected to an H4N external recorder, recording in WAV at the highest available quality setting. I think the gain is set to 30, but that will depend on your room. I have an arm hanging from the ceiling that is set right in front of my face, aimed at my chest, as close to me as possible but so it's not visible on camera. I've tried many other setups, this gives me the purest sound.
