I am occasionally interviewed via teleconference platforms (sometimes Zoom, sometimes through web interface applications). I need to improve the quality of my audio. I have a high-end (fast) Mac, and a variety of USB and 3.5mm microphones. The USB microphones tend to stutter (lose parts of the audio). The 3.5mm ones have a subtle hiss under it. I've been reading a bunch but am confused about phantom power and what exactly I want to have, between the microphone and the computer. Should there be a separate amp? If so, what kind? And if I want to control the bass and remove the hiss (use an equalizer on the audio signal before it goes out to the teleconference apps), is that hardware or software that I need? Can someone advise me on the terminology so that I know what I should be looking up. I can spend in the hundreds range (ideally not thousands). My goal is very reliable, good-sounding audio for speech.
I have figured out what I needed to know, mainly through trial and error with different devices and adapters. An XLR microphone - the AT2035 cardioid condenser microphone, plugged into an a Shure XLR-to-USB Signal Adapter, with the +48V Phantom Power switch turned on, works perfectly - nice clear sound, very low background hiss. I also tried it with the Focusrite Scarlett Solo (3rd gen) but the ratio of mic audio to hiss isn't as good.
