The IEC 60263:2020 Standard - Is a Picture Worth a Thousand Words?

With the proliferation of different electronic formats and screen grabs, aspect ratios, scales, and sizes for plotting frequency characteristics and polar diagrams, presenting audio measurement results in a clear and informative way is an even greater problem today than in the past! Geoff Hill explains what there is to know about the IEC 60263:2020 updated standard: Rules for scales and sizes for plotting frequency characteristics and polar diagrams... and what could go wrong.

Rational Acoustics and Audient announced the integration between the recently updated Smaart v9 audio and acoustical measurement software and the Audient EVO line of USB-C audio interfaces. The Smaart 9.1 update integrates the controls for phantom power and gain for Audient’s EVO devices - EVO 4, 8, and 16 - directly from within the Smaart interface. Additionally, gain tracking may be enabled to allow for automatic decibel offset recalculation for calibrated inputs.

Rational Acoustics announced the next major release version of Smaart (System Measurement Acoustic Analysis Real-time Tool), with many important new features. Smaart v9 will introduce a fundamentally revised software 64-bit code base, which unifies all editions to a common foundation and coherent interface: Smaart Suite v9, Smaart RT (Real-Time Edition), Smaart LE (Light Edition), and Smaart SPL (SPL Edition). The widely used acoustic test & measurement software platform, will be released on Tuesday, September 27, 2022.
