e ground-breaking deep networks were tailored for short-length raw audio files of around one second, with a sample rate accurate enough for speech comprehension (16kHz). Longer or higher sample rate audio files were difficult to address due to high computation demands. A major breakthrough comes from the WaveNET-like autoencoder in <span class="citation" data-cites="engel2017neural">(Engel et al. 2017)</span>, which was created as a new, data-driven synthesis technique for longer length audio files, extendi
