Learn more about the technologies found in Earthworks microphones and how they improve your sound.

Impulse Response

Impulse Response indicates the speed and accuracy of a microphone to reproduce fast transients. Learn more.


Phase indicates how much one frequency is delayed in time in comparison to other frequencies. Phase errors will smear transients and create other time related distortions. Learn more.

Frequency Response

Frequency response refers to the accuracy a microphone has over its stipulated (or operating) frequency range. Learn more.

Polar Response

A microphone’s polar pattern will indicate any changes or alterations in frequency response at specific points such as the front, sides or rear of the microphone (i.e. 0º, 90º, 180º, 275º, etc). Learn more.

Requirements for a High Definition Microphone

The difference you hear is like the difference you see when comparing a standard television picture to a high definition television picture. Learn the 7 criteria required to make a High Definition Microphone. Learn more.

Coverage Area

The polar response of conventional microphones is typically very poor, as they have significant losses of high frequencies at the sides of the microphone. Learn more.
