What was used in electric recording that differed from acoustic recording?

In electric recording, microphones and electronic amplifiers were used to capture sound, allowing for greater fidelity and the ability to record a wider range of frequencies compared to acoustic recording, which relied on mechanical methods like horns and diaphragms. This shift enabled more nuanced sound reproduction and the use of various sound manipulation techniques. Additionally, electric recording allowed for longer recording times and the ability to mix multiple tracks, advancing music production significantly.
