The manufacturer recently announced a new codec that allows wireless streaming of high-resolution audio.
Wireless earphones and other audio headsets are today the objects acclaimed by the general public to listen to music throughout the day.
Hi-res audio via Bluetooth headphones is soon to be a reality
However, the devices suffer from a problem related to the audio quality broadcast via the Bluetooth chips. Bandwidth being limited, these headphones are often limited to standard quality and prevent the broadcast of high-resolution songs.
We can also mention the case of Apple, which offers with its music streaming service Apple Music millions of titles in CD quality, and higher, but no device to listen to these songs wirelessly. AirPods, AirPods Pro, and AirPods Max are limited to 256 kbps AAC.
OPPO has decided to take tackled this problem and presented a new processor at its Inno Day 2022 conference that should allow everyone to enjoy lossless audio without sacrificing the comfort of their Bluetooth headphones.
OPPO unveils a new audio processor that significantly increases listening quality
The MariSilicon Y SoC can broadcast an audio signal at 24 bit/192kHz, i.e. values higher than CD quality, which makes OPPO say that its component is a first in the industry. The Bluetooth speed is 12 Mbit/s, which is 50% higher than the competition. It is also compatible with Bluetooth LE Audio technology.
OPPO is also unveiling a new Bluetooth codec, dubbed URLC for Ultra Resolution Lossless Codec. The MariSilicon Y chip is also compatible with LDAC, LHDC, L2DC, L3C, AAC and the good old SBC codecs.
This new SoC is also compatible with personalized spatial sound, which adapts to the ears of each user. OPPO has, to do this, presented a feature included on the processor, via its integrated NPU, and using artificial intelligence to isolate the voice or some of the instruments from the songs played in order to obtain a spatialized rendering. However, the track is not originally offered in this format.
The MariSilicon Y SoC should very soon integrate the brand’s next premium smartphones to be released in 2023. We will then see if the industry follows OPPO in this direction in the future.
