With more than 480 million registered users, Himalayan FM has grown into one of China’s largest audio-sharing platforms. What began as a traditional audio content platform gradually evolved into an interactive voice ecosystem, where users and creators engage in real-time conversations, multi-speaker rooms, and live audio entertainment.
As user expectations shifted from passive listening to active participation, Himalayan FM faced a critical challenge: how to deliver large-scale real-time voice interaction without compromising latency or sound quality.
Himalayan FM Profile and history
The launch on Himalayan FM took place in March 2013. In two years, the number of users has exceeded 200 million, becoming China’s fastest-growing and largest online mobile audio-sharing platform.
In 2014, it completed two rounds of high-value financing, laying a solid financial foundation for further leading the Chinese audio field. As of December 2015, the amount of Himalayan audio exceeded 15 million, and the cumulative number of playbacks in a single day surpassed 50 million. Thus, the market share in the mobile audio industry has reached 73%.
Business Challenges
Transitioning to real-time multi-person voice interaction required solving two fundamental challenges:
Ultra-Low Latency
Interactive voice rooms demand minimal delay to maintain natural conversation flow. Even small delays can disrupt rhythm and reduce user engagement. Himalayan FM required a transmission solution capable of maintaining low latency under high concurrency conditions.
Consistent High-Definition Audio Quality
Unlike standard live broadcasting, voice-linked sessions amplify audio processing challenges. Variations in microphone distance, device performance, and background noise create unstable sound quality. Echo cancellation, noise suppression, and gain control become essential in dynamic multi-speaker environments.
Additionally, weak network conditions introduce packet loss and jitter, which can severely impact real-time voice interaction.
ZEGOCLOUD Solutions for Himalaya FM
ZEGOCLOUD currently provides Himalaya FM with a multi-person voice link and an online KTV solution.
The self-developed private protocol based on UDP guarantees a stream transmission with a delay of about 200 milliseconds. Meanwhile, it uses smoothing network jitter, forward error correction, and frame loss compensation to solve the packet loss problem in a weak network. It can ensure low latency and clear and smooth voice calls.
Meanwhile, ZEGOCLOUD’s self-developed 3A algorithm solves the problem of audio processing in the voice scene:
- Adaptive echo cancellation
- automatic adjustment of the microphone volume
- psychoacoustic models
- improvement of 20dB + signal-to-noise ratio
Business Value
The main advantages are:
- More engaging live broadcasts through voice interaction among users increased the ways of playing games. Besides, it boosts platform traffic and improves competitiveness in the live broadcast industry.
- At present, the users of audiobook platforms generally do not pay much attention to the anchors. However, it brings numerous fan users and increases the stickiness of the platform users.
- Anchors don’t need to buy professional sound card equipment. They can have good sound quality effects only through mobile phones, which lowers the entry threshold for anchors and attracts more anchors to the platform.
There are two main scenarios that the ZEGOCLOUD solution addresses:
1) Two anchors connect to solo, and the audience can apply for interaction
2) Multi-anchor enters the room, then turns around to sing, play other team games, etc.
Conclusion
As audio platforms evolve from passive content consumption to interactive voice ecosystems, infrastructure performance becomes central to user experience. Real-time multi-speaker communication introduces strict requirements around latency control, network resilience, and audio processing quality.
Through its optimized transmission architecture and advanced audio algorithms, ZEGOCLOUD enabled Himalayan FM to scale interactive voice engagement to hundreds of millions of users without sacrificing responsiveness or sound clarity.
In large-scale real-time platforms, technical precision directly shapes business growth. By building on a stable, low-latency foundation, Himalayan FM successfully transformed its audio ecosystem into a dynamic, interactive community.
