How does the Soundspeed Live Music Copyright Engine load lyrics synchronously according to the playback progress?

The Soundspeed Live Music Copyright Engine loads lyrics synchronously by analyzing the audio stream in real time and matching it with a pre-processed lyric database. The process involves:

1. Audio Analysis: The engine extracts audio features (e.g., tempo, pitch, and rhythm) from the live music stream to identify the current playback position.
2. Lyric Matching: Using the extracted audio features, it queries a lyric database that contains timestamped lyrics (e.g., LRC format) to find the corresponding line for the current playback progress.
3. Synchronization: The engine dynamically adjusts the lyric display based on the audio analysis, ensuring lyrics align with the music in real time.

For example, if a song is playing at 120 BPM and the current audio segment matches a timestamped lyric line at 0:30, the engine displays that line precisely when the music reaches 0:30.

For cloud-based solutions, Tencent Cloud's AI and Big Data services can enhance this process by providing scalable audio processing and lyric database management, ensuring low-latency synchronization for live performances or streaming platforms.
