Spectral trancoder: using pretrained urban sound classifiers on undersampled spectral representations @ DCASE
Slow or fast third-octave bands representations (with a frame resp. every 1-s and 125-ms) have been a de facto standard for urban acoustics, used for example in long-term monitoring applications. It has the advantages of requiring few storage capabilities and of preserving privacy. As most audio classification algorithms take Mel spectral representations with very fast… Continue reading Spectral trancoder: using pretrained urban sound classifiers on undersampled spectral representations @ DCASE
