Abstract: Highlights•We propose a novel Efficient Wavelet-Transformer (EWT) for SID.•EWT increases the speed of Transformer by more than 80% and reduces GPU by more than 60%.•We propose an efficient Multi-level Feature Aggregation Module (MFAM).•We demonstrate the effectiveness of wavelets in Transformer models.
