WHAM!: Extending Speech Separation to Noisy Environments

dataset. For both enhancement tasks, we see a larger SI-SDR improvement in the 16 kHz max case than with 8 kHz min, likely because it is easy to enhance in regions where noise and speech do not overlap. However, we notice a rather large drop in performance between 8 kHz and 16 kHz for separate-clean, as well as a more moderate drop for separate-noisy.
