Microphone Recommendation

Manfred HB9FLU

The microphone with the best response by others and myself is the Sennheiser E945.

It delivers a crista clear and warm sound in one. Best buy so far.

Ken,

Thanks for the instant reply. I've done some additional experimenting and your suspicion about the levels was correct. It takes some experimenting with the mic level in the PC as well as the level in SmartSDR to get to workable settings.

I've also discovered that turning on the Processor immediately brings up the noise, I'm guessing it's raising the gain and picking up the ambient noise. As you indicated, the Downward expander is automatically disabled when the Mic source is PC so maybe it prevents this sort of thing when using a "local" mic.

I'm working on a Mac-based SmartSDR-like app and your techniques allowed me to prove that my Opus Tx implementation is working. Thanks again for sharing your technique, it was very helpful.

Thanks for the positive feedback.  
Indeed, when working with a local mic connection, the DEXP, when carefully adjusted, is very effective in limiting the background noise.  I use it all the time in my shack.

Good luck in your programming.  I long to learn C# and do some myself ... after I retire.....
