For instance I've put my eye on two mics (cardioid condenser ones).
One has -90dB sensitivity and frequency range of 20 - 20 000 Hz.
The other on has -46dB sensitivity and frequency of 50 - 15 000 Hz.
It's going to be used at the distance of no more than 11 inches / 30 cm from me.
I wouldn't like to buy something that would give me a sound not better than a smartphone, I want to get more clear/detailed speech.
Which specs should I prefer?
