Shulou(Shulou.com)11/24 Report--

During last year's Snapdragon Summit, Qualcomm launched the second generation of Qualcomm S5 and S3 audio platforms, both of which support the new features of Qualcomm's Snapdragon Sound Snapdragon listening technology. After the release of these two products, Qualcomm's audio technology is still evolving. Today, Qualcomm has launched a new solution for the second generation of Qualcomm S3 audio platform, designed specifically for Bluetooth adapters.

According to Qualcomm, the new second-generation Qualcomm S3 audio adapter solution brings many new features and features to everyone's wireless audio experience. First of all, the game latency, oriented to the game field, this new solution can achieve the lowest game latency so far, and can achieve an ultra-low latency of less than 20 milliseconds with the corresponding headphones, bringing a delay performance comparable to that of professional e-sports headphones.

The game audio latency experience brought by the new audio adapter solution is comparable to that of e-sports headphones based on 2.4G proprietary protocol. In contrast, the first generation of Qualcomm S5 and S3 audio platforms have an end-to-end delay of 80 milliseconds through a classic Bluetooth connection between mobile and TWS headsets or integrated headphones. The second generation Qualcomm S5 and S3 audio platform with LE Audio implementation of the end-to-end delay between mobile phones and headphones is 48 milliseconds. Therefore, the progress in game latency of the newly released second-generation Qualcomm S3 audio adapter solution is visible to the naked eye.

Not only that, this solution is a dual-mode solution that supports LE Audio (low Power Audio) technology, so it can support both classic Bluetooth and LE Audio.

At present, many devices, such as mobile phones and audio devices, do not support LE Audio, but with the new second-generation Qualcomm S3 audio adapter solution, these devices can achieve the functions of LE Audio. We can understand this newly released solution as the "transmitter" of LE Audio.

In terms of audio playback, the second-generation Qualcomm S3 audio adapter solution can bring feverish friend-level audio streaming performance, which currently supports 24-bit 96kHz, and will likely support higher resolution audio playback in the future. The products created by this Bluetooth adapter solution may also support lossless audio.

In addition, this new solution brings some new experiences through LE Audio, including Auracast ™broadcast audio. Auracast broadcast audio is a technology brand launched by Bluetooth Technology Alliance (Bluetooth SIG). It is a part of LE Audio technology and is essentially an one-to-many broadcast audio function. And Snapdragon Sound Snapdragon listening technology and LE Audio work together to bring enhanced audio experience for stereo audio recording and games, such as stereo audio recording, which can record both the left and right ears at the same time, that is, real stereo HD recording, just like a person walking past you, you can clearly distinguish his direction and position, instead of all the audio mixed together. This feature is expected to be well applied in future live streaming and other scenarios.

Overall, the new second-generation Qualcomm S3 audio adapter solution supports LE Audio Bluetooth adapters, Bluetooth transmitters, sound source devices or audio products in the form of wireless microphones at the application level. At the technical level, the ultra-low game latency of less than 20 milliseconds is achieved.

In addition, it uses advanced manufacturing process, and the power consumption can be as low as 5 Ma, which helps manufacturers to design and develop portable products. At the same time, it also has strong computing power, combined with the blessing of Snapdragon Sound Snapdragon listening technology, can achieve excellent connection consistency and stability.
