The audio core is the frequency range which the human ear finds most sensitive, between 2kHz - 5kHz.
In 1933, Harvey Fletcher and Wilden A. Munson conducted the first research on the subject. They played a series of tones to determine the listener's perceived loudness at different frequencies. The results showed that the frequency response of the human ear is non-linear. The perception of different frequencies also varies based on the amplitude of a sound.
Mix translation is one of the most important aspects of music production. Often a mix sounds great in the studio but not when played on other speakers. The truth is that most listeners are using small cheap speakers to listen to music. This means that your mix needs to sound great on earbuds.
As part of our company's research, we interviewed over 100 audio engineers. 85% of these engineers told us that mix translation was their biggest problem. Engineers spend hours bouncing mixes between their studio, car, laptop, and home stereo. This guessing game results in wasted time and added frustration. Soundways developed the Core Production Workflow to help engineers deal with mix translation.
Mixing drums is a challenging task for any audio engineer. Drum kits are usually recorded with at least three microphones. Some tracking engineers use up to fifteen. If your microphones are not carefully placed, time difference's can cause phase cancellations.
Often a drummer's natural dynamics will sound great live but not in the studio. If the drummer has a heavy hand on the hi-hat and cymbals, a harsh drum recording can result. Soundways has now developed the Core Production Workflow to help engineers mix drums.
