Software function
Professional-grade karaoke technology:
AI intelligent phonetic correction:
Based on the self-developed algorithm of Tianlai Lab, it supports pitch correction (±12 cent accuracy), rhythm alignment (error ≤50ms) and personalized timbre matching. Users can use the "sentence-by-sentence refinement" function to re-record a single sentence 5 times to generate a professional-level remix work.
Real-time chorus technology:
Adopting the SoundNet SD-RTN™ transmission network, the end-to-end delay of a double chorus is ≤85ms, and the synchronization error of a multi-person chorus is ≤100ms. It supports cross-platform (iOS/Android/PC) real-time mutual listening. In the Hongmeng version, the delay is optimized to 70ms through distributed technology.
Hardware collaborative innovation:
Self-developed karaoke headphones:
Built-in 10mm aviation-grade microphone (signal-to-noise ratio 70dB) and professional karaoke sound card, supports 12 kinds of sound effects (including 3 kinds of exclusive sound effects), and cooperates with the 5 kinds of scene sound effects of the National Karaoke APP to achieve "hardware + software" dual-effect sound quality improvement.
Multi-device linkage:
It supports screen projection on mobile phones, tablets, and smart TVs. Dolby Atmos can be called on the smart TV to achieve home KTV-level sound field effects.
Ultra-large-scale concurrent processing:
Cloud rendering architecture:
Adopting Tencent Cloud RT-ONE™ network, it supports millions of users playing karaoke online at the same time. The live streaming delay is ≤1.5 seconds, and the barrage message processing throughput reaches 100,000 messages/second.
Content security system:
Integrate Tencent Miying AI review system to intercept illegal content in real time (accuracy rate 99.98%), support national secret SM2/SM3 algorithm encrypted transmission, and user privacy data storage complies with GDPR standards.
Software features
Technology ecological integration:
Together with vivo, we define the industry standard for real-time listening of karaoke songs on mobile phones. In the Hongmeng version, the device’s sensing capabilities are used to automatically match earphone/audio-specific sound effects solutions to achieve an acoustic experience of “thousands of people, thousands of faces”.
Scenario-based innovation:
Launched industry-customized templates such as "Party Building Cantata" and "Corporate Annual Meeting" to support real-time choruses of more than 500 people, and provide functions such as dynamic lyrics scrolling and virtual stage background switching to meet the needs of government and enterprise users.
Data-driven optimization:
It processes more than 2 million user works every day, uses AI to analyze user behavior (such as vocal range distribution, song preferences), and dynamically adjusts sound effect parameters and recommendation strategies, increasing the playback volume of the works by 30%.
Software features
Technical indicators:
Audio encoding: Supports 192kbps two-channel stereo, and the AI noise reduction function can eliminate 40dB of environmental noise.
Concurrency capability: A single cluster supports 1 million users online at the same time, and server availability reaches 99.99%.
Response speed: song loading takes ≤2 seconds, and barrage sending delay is ≤300ms.
Compatibility:
Adapted to Hongmeng 5.0, iOS 17, Android 14 and other systems, it can achieve hardware acceleration on Snapdragon 8 Gen4, Kirin 9000S and other chips, reducing power consumption by 25%.
Certification system:
It has passed ISO 27001 information security certification and Class 3 Protection 2.0 Level 3 standard, and supports PCI DSS compliance audit. User data is encrypted and stored in Tencent Cloud Government Cloud nodes.
