RTA 311 Lecture Notes - Lecture 1: Cardioid, Schoeps, Shure
Document Summary
Frequency curve: lowest to highest sounds we can mic can hear. 0 db, - 130db spl our threshold for hearing. 194 db sound creates a vacuum and turns into a shockwave. As we get closer to subject, low frequencies become more present. Cardioid pick up pattern: focused at front, pretty much rejecting at rear. Stage mic: cus of severe rejection at rear. Directionality is not equal at all frequency: frequency response changes when you get on and off axis. Find the sweet spot: more focused at high frequency, less at low. More sensitive to plosives, handling noises and wind noises (like any direntional microphone) Really emphasise frequency from 2khz to 10khz: with this curve we can highlight the frequencies of humans speech in flattering way, rejects gross low frequencies. Can change tone/character of sound to fit instrument in studio session. If recording in stereo, angle 2 mics differently.
