Over the past few days, Redmi has been teasing salient features of the upcoming Redmi k40 series. In a recent teaser, the company said that this device supports Dolby Atmos which can eliminate crosstalk and simulate spatial surround sound effects. The latest teaser on this device shows that it has a new Hi-Res high-resolution wireless audio certification. Officially, the Redmi K40 dual flagships will have a higher audio resolution, greater dynamic range, and greater frequency response.
Hi-Res certification is commonly found in HiFi headsets and music players DAP. This standard was initiated by Sony and is jointly recognized by the Japan Audio Association, Consumer Technology Association (CTA), Digital Entertainment Group (DEG), and major recording companies. The standard stipulates that the indicators of audio files need to exceed CD sound quality, such as 24bit/192kHz. The parameters of audio playback devices also need to meet certain requirements.
At present, Hi-Res certification is issued by the Japan Audio Association JAS. Furthermore, the device needs to support LDAC or LHDC protocol to obtain the gold standard of Hi-Res wireless audio. The Hi-Res certification official website shows that two models (K11 and K11A) from Xiaomi were certified in January 2021. According to previous news, these two models are the Redmi K40 series.
