用于白噪音设备的多音频混播方法
By generating a sound source library and mixing configuration, and using mutual masking margin and suppression coefficient for frequency band energy control, the problem of unstable listening experience of white noise equipment when playing multiple sound sources is solved, achieving frequency band equalization and consistent output, and improving the controllability of interactive adjustment and cross-session consistency.

AI Technical Summary
Existing white noise equipment suffers from problems such as insufficient mutual masking control, imperfect interactive adjustment timing configuration, insufficient consistency between loop and noise management, and insufficient coordination between loudness and peak constraint at the output end when playing multiple sound sources, resulting in unstable listening experience and inconsistent parameter activation timing.
By generating a sound source library, mixing configuration, timing configuration, and loudness target, frequency band energy control is achieved using mutual masking margin and suppression coefficient, combined with look-ahead limiting and gain adjustment, to achieve frequency band equalization and consistent output.
It achieves consistent and predictable listening experience in scenarios with multiple audio sources, reduces short-term jumps, and improves the consistency and controllability of cross-session mixed playback output.
