What was the significant advantage of using electrical recording equipment starting around 1925?
Answer
It allowed for greater dynamic range by amplifying signals
Before 1925, recording quality was limited by the acoustic energy of the sound waves hitting the diaphragm. Electrical recording equipment changed this by converting sound into electrical signals that could be amplified before etching the disc. This transition meant the quality was no longer limited by the physical force of the sound wave, allowing the capture of much greater dynamic range, subtle details, and volumes that were far closer to the experience of a live performance.
