As A collaboration between Jünger Audio and Flux has brought the Level Magic loudness measurement, correction and management algorithm to a software format. Based on the underlying ITU-R BS.1770(-1/2/3) principle, Level Magic provides compatibility with EBU R128, ATSC A/85, ARIB TR-B32, FREE TV OP-59 and Portaria 354.
Designed to be audibly transparent, Level Magic uses a proprietary multi-loop approach comprising of three elements in parallel to measure, and if necessary correct, out of specification audio. An AGC section controls slower changing levels over time, while a fast-acting processor catches inaudible high-frequency overshoots that may otherwise cause detrimental effects in downstream processing or coding.
A brickwall filter provides effective True Peak limiting using a 2ms look-ahead to capture any intersample peaks. The resultant gain changing signal is a combination of all three elements.
The Level Magic algorithm is highly adaptive to the structure of the incoming audio and requires only a small number of parameters to be set by the user. The result is audio compliant with the selected standard but free of any unwanted artefacts such as pumping, breathing or distortion.
All major DAW platforms are supported (AU/VST/AAX/AS) for both Real Time and Offline (AudioSuite) processing in 32/64 bits under both Windows and Mac OS-X. Supported audio I/O formats include Mono, Stereo and Multichannel 5.1.
‘As the industry continues to demand and adopt software based solutions, we are proud to now be able to offer all the proven and tested benefits of Level Magic to those working in the DAW environment,’ says Jünger Audio MD Peter Pörs. ‘This software tool is the perfect complement to our line up of hardware based real-time processors and will position us well for further expansion into the audio production workflow market.’
‘We believe this collaboration to be a perfect match between two companies from two different parts of the industry, united by a passion for extraordinary audio products,’ adds Flux, CEO Gael Martinet. ‘Level Magic is a great addition to our current product range, meeting the growing demand for comprehensive loudness correction processors on the audio software market.’
