Today Netflix has released 'High Quality' audio - increasing its bitrate for DD+ Surely this is great news as we have incredible picture quality with 4K Dolby Vision and HDR and finally audio is catching up. Will something like this make Apple do the same with iTunes releases?
Could ALL iTunes films be released in DD+?
"The bitrate on 5.1 surround will increase from 192 Kbps to 640 Kbps. The bitrate used to deliver Dolby Atmos will increase from 448 Kbps to 768 Kbps. To enjoy Dolby Atmos you must subscribe to Netflix's 'Premium' plan.
The company explains that improved audio quality has been implemented as an adaptive stream, meaning that users with compatible devices - and a fast enough internet connection - will automatically get improved quality. The company is also using adaptive video streaming.
Netflix added that 'high quality audio' is available for all movies and TV shows with 5.1 surround and Dolby Atmos. It is using the Dolby Digital Plus format." (source: Flatpanelshd.com)
Netflix went on to say ""Our high-quality sound feature is not lossless, but it is perceptually transparent. That means that while the audio is compressed, it is indistinguishable from the original source. Based on internal listening tests, listening test results provided by Dolby, and scientific studies, we determined that for Dolby Digital Plus at and above 640 kbps, the audio coding quality is perceptually transparent. Beyond that, we would be sending you files that have a higher bitrate (and take up more bandwidth) without bringing any additional value to the listening experience,"
