He then explained the history of film sound, from Variable Area Optical Sound, through Dolby stereo, then to various digital formats right up to the current innovation of Dolby Atmos. He explained the processes involved in film sound mixing, and the challenges – including the variability in theatre reproduction levels, and the demands for an international release (a clean, dialogue-free mix but with absolutely every other sound element intact).
We then moved into the Foley and ADR Studio, where Doron explained with great detail the art and craft of Foley work, and the special techniques involved in voice recording for dialogue.
The evening evolved into a free-ranging discussion about film sound and other (loosely) related topics, and we thank Doron for being so generous with his time and knowledge about this specialist part of the audio engineering science and craft.
