Redmi has since officially announced that it will unveil the Redmi K40 series via live video at 7:30 pm on February 25. According to the company, this event is one “Dual flagship” live broadcast. This sparks speculation that the event will see the launch of the Redmi K40 and Redmi K40 Pro. Today, Redmi also announced that it is fully upgrading the Redmi K40 series sound quality. This series comes with support for Dolby AtmosAccording to the company be it built-in stereo speakers or headphones, it unleashes sound everywhere Travel directions.
Redmi K40 Series Dolby Atmos Working Principles
In addition, Redmi demonstrated the principles of Dolby Atmos technology. It emphasizes that the dual speakers can produce surround sound in all directions. With Dolby Atmos, the device can output any sound effect as a single audio element. This audio output is independent of other parts of the audio track. Whether it’s a child’s screaming or a helicopter taking off, content creators can accurately separate the sound effect. Users can deal with audio elements anywhere in three-dimensional space without interference.
The headsets and built-in speakers of mobile devices are usually left and right channels. To create a realistic experience of height and surround sound, a two-channel mobile system must first have a head-related transmission function (HRTF). HRTF describes how incoming sound sources from different locations around us reach our ears.
Depending on the position of the noise emission, one ear may lag behind the other to perceive the sound. This means that the sound quality may vary slightly on each earThese differences arise from the interference on the listener’s head, torso and outer ears.
Dolby Atmos improves audio quality
Streaming Dolby Atmos mixing supports up to 128 simultaneous audio objects. It also includes metadata describing the location of each object in the space. In addition, the Dolby Atmos processor on the mobile device can apply a variety of HRTFs to the metadata to reproduce the spatial information in the stereo signal. When listening through headphones, the stereo soundtrack can accurately simulate theater sound effects (including the top sound effects), creating a breathtaking and spacious experience.
To reproduce the same experience through the device’s built-in speakers, additional processing is required. In addition, speakers will produce a natural “crosstalk” phenomenon in our ears, which is not conducive to multi-channel simulation. The Dolby Atmos processor can eliminate this crosstalk and then apply HRTF to produce a multi-dimensional sound field and motion effect for audio objects.
