Zero-upsampling in audio generators replicates the low-frequency spectrum at fixed intervals, creating architecture-dependent spectral peaks that enable a simple, interpretable detector for AI-generated music.
It’s not really enjoyable to make music now [...] I think the majority of people don’t enjoy the majority of the time they spend making music
