ECM Plus +++ /LAS VEGAS/ – Booth SU5520 – Fraunhofer IIS and plug-in designer Sonnox has launched a new broadcast quality, post-production audio codec to use high-quality, bandwidth-saving MPEG audio with AAC and mp3 formats and portable into audio editing software.

Fraunhofer said it would be showing a mastering-quality plug-in developed with Sonnox that will bring the audio quality and bandwidth savings of its codecs to the broadcast and professional markets. 

Targetted at broadcast professionals, the new plug-in is designed for everyday use that include the possibility to monitor the quality of each codec output in real-time.

Installing the plug-in in digital audio workstation software will enables files to be saved in formats such as AAC, HE-AAC, mp3, or the lossless formats HD-AAC and mp3HD.

The new plug-in enables real-time monitoring of the codec output in the audio software during mixing and mastering and is able to encode to multiple formats and bit-rates at the same time, Fraunhofer confirmed.

“Fraunhofer will be showing a mastering-quality plug-in developed with Sonnox that will bring the audio quality and bandwidth savings of our codecs to the broadcast and professional markets” commented Robert Bleidt, General Manager Fraunhofer USA Digital Media Technologies. “For example, the use of HE-AAC for podcasts could save 2/3 of a station’s download bandwidth costs. Our codecs can also save downloading time and provide higher quality for demo and approval clips, or for sending voiceovers or actualities. With HE-AAC now supported in Windows Media Player 12, QuickTime, WinAmp, and Flash streaming as well as Android and iOS devices, we wanted to offer the industry a professional tool for preparing compact, quality content for these platforms.”

The plug-in is also the first professional production offering of Fraunhofer’s surround codecs mp3 Surround, AAC Multichannel, and HE-AAC Multichannel, enabling surround content to be encoded in these formats for gaming or electronic distribution. Sonnox has developed an intuitive FFT display to illustrate the input signal, output difference signal, and a unique graphical indication of the audibility of codec-induced noise. The plug-in offers decoder clipping meters to reveal potential decode overloads, instant A-B auditioning to enable engineers to glitchlessly switch between codecs, and an ABX blind listening mode to aid in codec comparisons.
