Flagship Bluetooth Audio SoC OPPO Releases the Second Self developed Chip Mariana Y
Yesterday (December 14), the OPPO Future Science and Technology Conference was held as scheduled, and the first one was the second self-developed chip that everyone paid close attention to. This self-developed chip is not intended for mobile phones, but is specially designed for Bluetooth earphones. It uses the world's most advanced N6RF process, integrates a dedicated NPU unit for the first time in the world, supports the world's fastest 12Mbps ultra-high speed Bluetooth, and is named Mariana MariSilicon Y.
Jiang Bo, senior director of OPPO chip products, said: "Mariana MariSilicon Y is the second self-developed chip of OPPO, marking the further development of OPPO's self-developed chip capability. As a flagship chip with advanced technology, we expect that the key technology of this chip can solve the key problems of" sound quality "and" intelligence "in the user's audio experience, and provide chip power for the next generation of flagship Bluetooth audio devices."
For a long time, consumers still cannot obtain the sound quality comparable to that of traditional wired earphones through Bluetooth earphones. Due to insufficient Bluetooth speed, a large amount of data of high-quality audio (48kHz/24bit lossless audio and above) can only be transmitted via cable, and cannot be carried wirelessly via Bluetooth.
As the first Bluetooth audio SoC chip independently developed by OPPO, Mariana MariSilicon Y achieved the wireless transmission of 192kHz/24bit lossless audio via Bluetooth for the first time through the world's fastest 12Mbps Bluetooth speed, reaching the peak of Bluetooth audio quality; It is the first time to integrate a dedicated NPU unit. Mariana MariSilicon Y provides advanced AI computing power up to 590 GOPS for the rapidly developing computing audio, and for the first time realizes sound separation technology on the headset side, bringing a more personalized listening experience; Taking the lead in applying the world's most advanced N6RF process, Mariana MariSilicon Y can combine advanced high performance with flagship endurance experience.
Mariana MariSilicon Y realized the world's fastest 12Mbps ultra-high speed Bluetooth solution for the first time through innovative Bluetooth bottom hardware bandwidth design, which is 4 times the speed of traditional Bluetooth. Combined with the leading URLC lossless encoding and decoding technology, Mariana MariSilicon Y is the only Bluetooth chip that currently supports 192kHz/24bit lossless audio.
At the same time, Mariana MariSilicon Y supports the dynamic rate adaptive technology, which can automatically adjust the encoding and decoding rate in the ultra wide range of 80Kbps to 10Mbps. It always provides stable and non jamming audio quality, no matter in shopping malls with complex signals or quiet study. By supporting mainstream encoding and decoding technologies, Mariana MariSilicon Y helps users always ensure first-class audio quality experience when connecting cross brand devices.
Compared with the traditional DSP (digital signal processor) units used to process audio data, Mariana MariSilicon Y integrates a dedicated NPU computing unit for the first time to provide the most powerful power for audio computing with the advanced AI computing power of 590 GOPS. Compared with the most advanced DSP unit at present, Mariana MariSilicon Y is a high-performance NPU unit, which can provide more than 23 times of computing power and more than 16 times of computing energy efficiency. It can efficiently run the advanced AI audio algorithm that the DSP unit could not even execute before.
Through sound separation technology, Mariana MariSilicon Y supports the feature of customized full scene sound, which can intelligently identify and separate vocals and instrument groups in music, and help users customize and control the volume and spatial position of each track, such as vocals, drums, bass, etc. For example, amplify and pull the vocals close to their ears, or switch the drums from left to right to create their own unique listening sense.
Based on the sound separation technology, Mariana MariSilicon Y also supports the feature of omnipotent full scene sound, which can transform and upgrade the traditional dual channel music into a new effect of full scene sound, and transfer the option of this advanced listening sense from the production end to the user end. Traditionally, if the music is not produced in the panorama sound format, users cannot experience this effect. Universal panoramic sound allows users to more flexibly match their favorite music and panoramic sound effects to achieve a more immersive hearing.
In addition, Mariana MariSilicon Y's abundant computing power can achieve consistent audio experience when users use multi terminal devices without relying on the computing power of mobile phones. For example, universal and personalized full scene sound based on sound separation technology can still achieve the same functions and effects when paired with different hardware devices such as mobile phones, computers, televisions, tablets, etc.
At present, the Future Science and Technology Conference is not over. Today, OPPO will officially release the new second generation folding screen mobile phone OPPO Find N2 series at the Future Science and Technology Conference. Partners interested in this mobile phone can pay attention to the OPPO Future Technology Conference this afternoon.
