xHE-AAC codec added to HLSdirect, http encoders
April 26, 2017
DIAMOND BAR, Calif.—Modulation Index/StreamS is unveiling a new product at this year’s NAB Show, as well as demonstrating a new feature into some of its other line of encoder products.
The StreamS 3121 audio encoder platform is an embedded customizable computer system designed for live streaming audio applications. The unit features the StreamS standards-based encoder application as well as audio processing, content insertion and full audio playout systems and has the ability to run other qualified streaming encoder applications. The encoder comes in a 1RU chassis with standard or optional dual redundant/hot swappable power supplies. It is powered by Microsoft Windows 10 Enterprise LTSB Embedded, a fast intel Xenon processor, ECC RAM, SSD, RAID options and dual NICs. The system is compatible with major network audio drivers and carts; it also support analog and digital I/Os. It can handle as many as 16 sources for encoding with four sessions per source or eight sources with Orban Optimod-PCn audio processing.
The company has also announced that it is implementing Fraunhofer’s xHE-AAC codec with its line of HLSdirect, http encoders. The streaming audio technology with the xHE-AAC can operate with standard web servers and in the cloud. It is capable of speech and music transmission at bit rates as low as 16kbs for stereo. The MPEG xHE-AAC is the low bit rate extension of the AAC audio codec.
In addition, Modulation Index/StreamS is also demonstrating the StreamS HiFi radio app for iOS, which supports xHE-AAC and multi-channel AAC surround streams. The app features a directory of more than 5,000 AAC/HE-AAC streams and allows arbitrary stream URL entry from within the app.
All of these products will be on display at the Modulation Index suite at the Westgate Hotel during the 2017 NAB Show.
