Audio And Hi-Fi Handbook, Third Edition
In June 1983, Sony introduced high fidelity audio to videotape as Beta Hi-Fi. For NTSC, Beta HiFi worked by placing a pair of FM carriers between the chroma (C) and luminance (Y) carriers, a process known as frequency multiplexing. Each head had a specific pair of carriers; in total, four individual channels were employed. Head A recorded its hi-fi carriers at 1.38(L) and 1.68(R) MHz, and the B head employed 1.53 and 1.83 MHz. The result was audio with an 80 dB dynamic range, with less than 0.005% wow and flutter.

Sony was confident that VHS could not achieve the same audio performance feat as Beta Hi-Fi. However, to the chagrin of Sony, JVC did develop a VHS hi-fi system on the principle of depth multiplexing approximately a year after the first Beta Hi-Fi VCR, the SL-5200 was introduced by Sony. Despite initial praise as providing "CD sound quality", both Beta Hi-Fi and VHS HiFi suffered from "carrier buzz", where high-frequency information bled into the audio carriers, creating momentary "buzzing" and other audio flaws. Both systems also used companding noise-reduction systems, which could create "pumping" artifacts under some conditions. Both formats also suffered from interchange problems, where tapes made on one machine did not always play back well on other machines. When this happened and if the artifacts became too distracting, users were forced to revert to the old linear soundtrack.

An analog measurement microphone (Dayton Audio's EMM-6, forexample) will need a suitable interface with a mic preamp and phantom power, such as Steinberg's UR22 MkII or theFocusrite Scarlett Solo.
