The next important development was 4-track recording. The advent of this improved system gave recording engineers and musicians vastly greater flexibility for recording and overdubbing, and 4-track was the studio standard for most of the later 1960s. Many of the most famous recordings by The Beatles and The Rolling Stones were recorded on 4-track, and the engineers at London’s Abbey Road Studios became particularly adept at a technique called “reduction mixes” in the UK and “bouncing down” in the United States, in which several tracks were recorded onto one 4-track machine and then mixed together and transferred (bounced down) to one track of a second 4-track machine. In this way, it was possible to record literally dozens of separate tracks and combine them into finished recordings of great complexity.
Unlike the film image that creates the illusion of continuity, soundtracks are continuous. This means that if film with a combined soundtrack is cut and spliced, the image will cut cleanly but the soundtrack will most likely produce a cracking sound. Fingerprints on the film may also produce cracking or interference.

A new high-performance audio codec called ASPEC (Adaptive Spectral Perceptual Entropy Coding) is presented as the result of further improvements of OCF and contributions by Hannover University, AT&T, and Thomson. The development partners had proposed ASPEC already in 1989 for the forthcoming MPEG audio standard.
Early 1970s: Prof. Dieter Seitzer of Erlangen-Nuremberg University in Germany begins wrestling with the problem of transmitting speech in high quality over phone lines. Although a first patent application was rejected, he establishes a group of students interested in audio coding research who start tackling the problem for their diploma and Ph.D. theses.

Reel-to-reel recording tapes were invented. They were large and unwieldy, and mainly used by professional recording studios and radio stations.
The invention and proliferation of audio cassettes were almost as quick as their sad demise. Here’s a quick run-down of the rapid rise, and equally swift decline of tapes.
