Linear Acoustic was founded in 2001 with the introduction of the OCTiMAX 5.1 audio processor. With the onset of digital television came myriad problems involving loudness and digital audio control. Linear Acoustic turned their attentions to solving these problems at every stage of the digital audio chain and soon developed a product range that made digital broadcast sound and work as it should.
Audio over IP (AoIP) has been embraced by the radio side of broadcasting for many years where the myriad advantages of networked audio via the Livewire+ AES67 standard is well known. Now, AoIP is available for television audio thanks to Linear Acoustic AERO.soft™. The Linear Acoustic SDI xNode de-embeds two separate HD/SD-SDI inputs, converts it to up to 16 channels of Livewire+ AES67 audio, makes it available for processing, upmixing, and encoding in the brand-new AERO.soft Processing Engine, and then re-embeds the audio into two independent SDI outputs. This provides unmatched flexibility, scalability and channel density.
In 2010, Linear received a Technical Emmy® for "The Pioneering Development of an Audio/Metadata Processor for Conforming Audio to the ATSC Standard," and has provided upmixing, loudness metering, encoding products, and technical support for NBC’s coverage of the 2008 Bejing Summer Games, the 2010 Vancouver Winter Games, the London 2012 Summer Games, the 2014 Sochi Winter Games, and most recently, the 2016 Summer games in Rio.
