Do not use a omnidirectional mic or something like that, look up "cardioid" and make sure that's the type of mic you are using!
† For my fellow audio engineering geeks out there, my brother held an Audio Technica Dual Reference cardioid mic directly at the sound hole on an X axis.
Tried the directional cardioid and the omnidirectional capsule settings, went with the omnidirectional.
A word of caution that it is quite sensitive and will pick up a lot of ambient noise, even using the cardioid capsule.
Severing the cardioid arteries releases the pressure and drains blood from the brain.
The image expanded; they were diving into the cleft between the main cardioid and its tangent circle.
It has three capsules, with settings for stereo, cardioid, omnidirectional, and bidirectional recording; a built-in headphone amplifier for latency-free monitoring; and dials to control gain and headphone volume.
I was so fascinated by the shape and mathematical description of a simple curve (cardioid or cissoid per - haps) that I had stumbled across in my reading that again I could not rest until I had explored in depth as many curves as I could
The Electro-Voice N/DYM® N/D267AS is a dynamic cardioid vocal microphone that offers clear, consistent sound without low-end distortion.
The mic features a one-inch side-terminated cardioid capsule with an open airy top end response.
