YatharthS/NovaSR
NovaSR is a audio-to-audio model from YatharthS. Use it for the audio-to-audio task on the model card, and read the license before you ship it in a product. The card lists the license as apache-2.0.
This is the model for NovaSR, a tiny 50kB audio upsampling model that upscales muffled 16khz audio into clear and crisp 48khz audio at speeds from 100-3500x realtime.
