Identified partially replicated training examples from the full TANGO model.
For each generated example we show the top match found in the training set for both similarity methods explored in our paper - CLAP and mel. While the generated sounds are not identical to the training data, they have striking similarities in terms of features such as event onsets, which appear to be replicated from the training data.
