Streaming platforms have brought us a new way of consuming content, allowing us to fill any gap we have throughout the day with a few minutes of a chapter from our favorite series, or a movie that we have halfway through. In addition, many users have discovered an element that few valued until recently: sound.
Good audio is just as important as the image itself. Both the music, the voices and the special effects. That it sounds good how a door opens, how the characters breathe or that that nuance in a sentence reaches us clearly even if the volume is not very high. This has been possible thanks to the use of helmets in a generalized way, so the platform announces changes. And for the better.
Sound with “studio quality”
Netflix has begun to update the Android application (version 9 or higher) with what they call from the platform as ‘studio quality’ sound thanks to the use of a new codec called xHE-AAC. That is, an improved version (extended as the Anglo-Saxons say) of the HE-AAX with MPEG-D DRC that, basically, is able to balance the audio to harmonize its volume throughout all the content we see.
Surely it has happened to you on occasion how in a chapter there are moments in which the volume seems to rise to the maximum, almost to the point of breaking, and after a few seconds, it goes down again to levels that we practically do not hear. Thanks to this new codec, we will not have those peaks and the feeling will be of a much more constant sound environment, quality and immersive.
Parallel to that ‘studio quality’ advertised by Netflix, this new sound codec is able to adapt more easily to the connection quality that we have at all times. It is not the same to watch content under the umbrella of a Wi-Fi network than to do it on the street with mobile data where there are areas with greater or lesser coverage and transmission speed. With this xHE-AAC changes are much better attenuated without giving the impression of sound degradation, although 4G is not going in the best possible way.
This improvement in audio it will allow us to set a constant volume for all the content we see within Netflix, and it will remain that way until we decide to change it, something that we are going to appreciate because it will serve to better adapt the exact point at which we want to enjoy series and movies.
