The Evolution Of Music Storage

The field of audio evolved over the last 170 years starting with the human voice first being imprinted on paper covered in soot, on a device known as the phonautograph. It would evolve into the wax cylinder phonograph and eventually the disc-based one, we know today.

Mechanical sound storage would be replaced by electrical-based sound reproduction, via microphones and loudspeakers. The sound could now be transmitted over lines and via radio.

The medium of vinyl records would soon be accompanied by the advent of magnetic tape storage. Magnetic tape storage allowed for sound editing and convent storage. As well as being able to be transferred into other mediums such as optical audio.

Electrical sound storage also brought the concept of signal processing with it. The frequency components of sound could be analyzed and modified to enhance quality, fulfill storage needs, and for artistic effect.

Several common audio signal procession techniques discussed are audio filters, dynamic range compressors and noise reduction.
