Condenser microphones, on the other hand, remain linear below 50 Hz and some are linear even down to 20 Hz. Condenser microphones are also more sensitive than electro-dynamic types because of their use of pre-amplifiers.
What is a good microphone frequency range?
A microphone with a frequency response range of around 80 Hz to 15 kHz would make a good choice for a vocal mic. However for miking snares and toms, you would look for a range that starts lower, at around 50 Hz, and for a bass drum mic, you will want a low end of 40 Hz or even lower, down to 30 Hz.
Is higher Hz better for microphone?
The golden rule: the higher the sample-frequency is, the better is the sound-quality (although I think only a trained ear may able to resolve the difference). On the other side, a higher sample-frequency will lead to bigger audio-files in the case you perform records.
Is a 20Hz mic good?
Yes, a microphone with a frequency response of about 20Hz to 20 kHz is good.
