DESCRIPTION:Next generation audio (NGA) formats have become standard in the
  distribution pipeline for premium cinematic content. This has given the c
 ontent creator the flexibility to render to various speaker configurations
  while incorporating channel\, object\, and scene based description format
 s. However while NGA for home entertainment is gradually getting adopted b
 y broadcasting and OTT platforms\, the majority of audiences still consume
  content on devices with stereo speakers such as TVs\, mobile phones\, lap
 tops\, and tablets. Studies also have shown that personal devices are gett
 ing more and more viewing hours. Therefore delivering a better experience 
 to the audience using stereo speakers while maintaining artistic intent in
  sound has become a critical issue in this era. In this paper we introduce
  Ambidio—a two-channel audio deliverable that takes advantage of the compa
 ctness of the stereo signal stream while delivering surround sound-like ex
 periences through stereo speakers with robust psychoacoustic models. The w
 orkflow for producing an Ambidio deliverable is presented here. It was dev
 eloped through close collaboration with experienced re-recording mixers in
  the industry to ensure seamless integration with existing post production
  pipeline for both feature films and episodic television. Extensive listen
 ing tests are conducted amongst audio professionals to compare Ambidio wit
 h the original surround sound mix\, and the results show that the Ambidio 
 version\, with two channels of audio\, can faithfully preserve the envelop
 ment of the mix while maintaining the color of the sound. Multiple encodin
 g and decoding procedures are also tested to emulate the delivery pipeline
  of leading broadcasting and streaming platforms of both video and audio\,
  under different encoding conditions even with low sample rates and low bi
 t rates. The test results show that the encoding does not affect the immer
 siveness\, and sound quality stays the same as the regular stereo delivera
 ble going through the same procedure. The immersive stereo version can ser
 ve as a good alternative deliverable for home entertainment including film
  and TV.

X-ALT-DESC;FMTTYPE=text/html:Next generation audio (NGA) formats have becom
 e standard in the distribution pipeline for premium cinematic content. Thi
 s has given the content creator the flexibility to render to various speak
 er configurations while incorporating channel\, object\, and scene based d
 escription formats. However while NGA for home entertainment is gradually 
 getting adopted by broadcasting and OTT platforms\, the majority of audien
 ces still consume content on devices with stereo speakers such as TVs\, mo
 bile phones\, laptops\, and tablets. Studies also have shown that personal
  devices are getting more and more viewing hours. Therefore delivering a b
 etter experience to the audience using stereo speakers while maintaining a
 rtistic intent in sound has become a critical issue in this era. In this p
 aper we introduce Ambidio—a two-channel audio deliverable that takes advan
 tage of the compactness of the stereo signal stream while delivering surro
 und sound-like experiences through stereo speakers with robust psychoacous
 tic models. The workflow for producing an Ambidio deliverable is presented
  here. It was developed through close collaboration with experienced re-re
 cording mixers in the industry to ensure seamless integration with existin
 g post production pipeline for both feature films and episodic television.
  Extensive listening tests are conducted amongst audio professionals to co
 mpare Ambidio with the original surround sound mix\, and the results show 
 that the Ambidio version\, with two channels of audio\, can faithfully pre
 serve the envelopment of the mix while maintaining the color of the sound.
  Multiple encoding and decoding procedures are also tested to emulate the 
 delivery pipeline of leading broadcasting and streaming platforms of both 
 video and audio\, under different encoding conditions even with low sample
  rates and low bit rates. The test results show that the encoding does not
  affect the immersiveness\, and sound quality stays the same as the regula
 r stereo deliverable going through the same procedure. The immersive stere
 o version can serve as a good alternative deliverable for home entertainme
 nt including film and TV.
