Analysis of audio solutions based on wireless communication
Many scenes in daily life are closely related to the audio experience, and people are paying more and more attention to experience when using related audio equipment. Relatively common ones are listening to music, watching videos, making voice calls, playing games, etc.
The emergence of wireless communication technology has freed human beings from the limitation of earphone wires, and Bluetooth technology has enabled human beings to explore and enjoy the wonderful wireless audio experience in a more accessible way.
As a new generation of Bluetooth audio technology standards, LE Audio will improve standard Bluetooth audio performance and empower and escort the further development of the audio industry.
The new generation of devices based on this technology will also provide users with the experience and sharing of wireless audio—in a whole new way.
Low latency and high sound quality inject new vitality into the audio field
Based on its core audio technology, Actions has seized the technical features and new opportunities of Bluetooth 5.3 and LE Audio. It aimed at three pain point application scenarios in the current audio application market: wireless home theater, wireless gaming headsets, and wireless microphones, respectively. A corresponding first-generation solution was launched, also based on technological innovations within the scope of the latest Bluetooth standard.
Low latency high sound quality wireless home theater solution
ATS2835PL low-latency 5.1-channel high-quality home theater solution adopts the coexistence mode of Bluetooth 5.3 LE Audio and classic Bluetooth. The delay based on LC3+ coding can be as low as less than 15 milliseconds. Compared with the 2.4G private protocol, the power consumption and sound quality are more deficient. It can coexist with classic Bluetooth and can support up to five channels. The subwoofer in the home theater and the two speakers behind it can be connected wirelessly, and a low-latency, high-quality wireless audio experience can be achieved through Bluetooth LE Audio. Let the home theater no longer be cumbersome, open the immersive movie-watching expertise anytime and enjoy a wonderful movie-watching time.
Low-latency, high-quality wireless gaming headset solution
ATS2831PL low-latency, high-quality wireless gaming headset solution; the end-to-end delay is less than 20 milliseconds, significantly reduced compared to classic Bluetooth. At the same time, it is fully compatible with PC/game consoles/mobile phones and supports the coexistence of LE Audio and classic Bluetooth.
If the user comes in while wearing a gaming headset, he can answer the phone without interrupting the game. After the call is finished, it can be restored to Gaming without interrupting the game to answer calls with another headset.
At the same time, it supports two-way 48KHz high-definition voice transmission, which can transmit high-quality game background sound and meet the needs of different game players for high-quality voice conversations. Realize clearer and higher-fidelity voice calls, wirelessly bring call quality comparable to wired calls, and bring better sound quality performance, bringing users a more immersive high-quality gaming experience.
Low-latency, high-quality wireless microphone solution
The wireless microphone is a product of Actions Technology that maximizes latency. The end-to-end latency can be as low as ten milliseconds. It integrates low-latency transmission, high-quality audio codec, and AI noise reduction and supports LC3+ codec. Support two messages and one reception, full link 48KHz high-definition voice transmission.
In recent years, the trend of short video and live broadcasts has become stronger and stronger, and wireless microphone products have emerged as the times require and have gradually entered the public eye. It must be compact, portable, and meet the requirements of very low-latency, high-quality audio transmission to achieve audio and video synchronization. It also needs to support two transmissions and one reception or multiple transmissions and one reception. The low-latency wireless microphone solution developed based on the Actions chip has been applied in many well-known brands worldwide.
In the future, based on the profound technical accumulation and technical advantages in the audio field over the past 20 years, Actions will bring customers product solutions with outstanding performance through continuous R&D and technical iterative upgrades, empower more new use cases, and continue to serve The vast number of users will bring better overall sound quality and seamless, immersive audio experience, and inject more new vitality into the audio field with low-latency and high-quality sound technology.
