摘要：As electric network frequency is sometimes embedded in audio signals when the recording is carried out with the equipment connected to an electrical outlet, electric network frequency estimation is an important task in audio authenticity. After the theoretical analysis, a novel electric network frequency estimation method based on linear canonical transform is proposed from anti-multipath interference point of view. The experimental results demonstrate that this model performs well with high precision in complex noisy environment.
