Eye to Eye: Whats even newer in test and measurement 2010

Sound is often regarded as playing a subordinate role to visuals in film, TV and video production, but the finest directors and producers have insisted on taking as much care over the sonics of a production as the visuals.

Acoustics is usually regarded (or often disregarded) as a black art that is practiced with no discernable science involved, with a great reliance on ears for measurement and blind faith as a method statement.

This flexibility is crucial for all field applications, in which broadcasters frequently must accommodate a variety of formats, and not always those they anticipated.

The Loudness Issue in Todays Audio Systems

For a while the television standards bodies got a grip and succeeded in pulling nearly everyone along the ‘SDI’ track; now itself expanded to HD-SDI and 3G-SDI – carrying a multit...
