RTM and Stagetec Asia put the spotlight on audio loudness
MALAYSIA: The Stagetec Asia Mediagroup Academy collaborated with Radio Televisyen Malaysia (RTM) recently for two days of audio training catering to the industry’s increased focus on audio levelling and loudness. The training was offered to participants from a range of broadcast backgrounds, including transmission, radio and TV production, and was led by experienced systems engineer John Anthony. Receiving great feedback from participants who attended, Stagetec Asia is planning an advanced level workshop in 2017.
‘The fundamental understanding of analogue and digital audio engineering encompassing level and loudness is now with the participants,’ stated Mr Anthony following the workshop. ‘They are well equipped and prepared to embrace new audio technology to further enhance the level of audio quality that is required by a professional organisation. The participants have shown a very keen interest to learn about audio. There are still things to learn and I hope they will get used to the new way of working.’
The training saw Mr Anthony begin by identifying individuals’ jobs and roles in each department, to grasp an understanding of an audio workflow which participants may encounter. The session went on to cover the theory and real-word use of audio measurement and levelling technical skills. One of the highlights of the day saw participants exposed to EBU loudness standard and loudness variations of case studies that reportedly helped them to get a clear picture of the loudness concept.
‘Throughout this course we learnt that loudness normalisation is the solution to counteract this problem,’ added Nurulhusna Mohamad Kasim, assistant director broadcast technology, RTM. ‘In FM, loudness is mainly balanced or controlled but in the case of digital broadcasting, it should be possible to achieve a balanced loudness profile. While the human ear is the best tool, audio metering can be improved with tools like a loudness meter. We were delighted to share with participants the technology and possible solutions.’
