Netflix is offering a newer audio experience starting today for its paid subscribers. The company claims it as “high-quality” audio which will support higher bitrate for devices with 5.1 or Dolby Atmos. So if you have been watching Netflix on a TV with the best audio technology but missed out on a better sound, this new addition will definitely boost the overall audio dynamics while you watch your favorite TV shows and movies.
The company spoke in detail about bringing studio quality sound across devices in a full length post on their Tech blog page:
If you’ve ever been in a professional recording studio, you’ve probably noted the difference in how things sound. One reason for that is the files used in mastering sessions are 24-bit 48 kHz with a bitrate of around 1 Mbps per channel. Studio mixes are uncompressed, which is why we consider them to be the “master” version.
In addition to deciding 640 kbps — a 10:1 compression ratio when compared to a 24-bit 5.1 channel studio master — was the perceptually transparent threshold for audio, we set up a bitrate ladder for 5.1-channel audio ranging from 192 up to 640 kbps. This ranges from “good” audio to “transparent” — there aren’t any bad audio experiences when you stream!
Often the subtlety of sound may go unnoticed, but it can have a profound impact on the atmosphere of a scene and fundamentally change how a viewer responds to it. Supporting and delivering on the vision of our creative partners has always been incredibly important to us, and sound is something we’ve been really focused on
