DJI | Audio Algorithm Engineer
2020.04 – 2023.08
Mainly responsible for sound pickup algorithm development and maintenance for motion cameras and gimbal cameras.
- Stereo sound pickup effect of multi-microphone devices far exceeds competitors (can be experienced by recording videos with Pocket 2/Action 2 and competing products and playing back).
- Wind noise suppression algorithm for multi-microphone devices: Based on multi-channel recording, this algorithm ensures clear voice of the holder even at motorcycle-like wind speeds, far surpassing supplier algorithm outputs.
- Participated in establishing the audio quality evaluation system.
Achievements: S-tier performance for 3 years twice; blind listening tests showed the product’s stereo pickup and wind noise elimination far exceeded competitors.
