This repo is Unofficial implementation of paper Masked Autoencoders that Listen. Audio-MAE first encodes audio spectrogram patches with a high masking ratio, feeding only the non-masked tokens through encoder layers. The decoder then re-orders and decodes the encoded context padded with mask tokens, in order to reconstruct the input spectrogram.
- Most of the code borrowed from repos mentioned in reference section below.
