In this video I cover the "High Fidelity Neural Audio Compression" paper and code.
With 6 kbps they already get the same audio quality (as measured by the subjective MUSHRA metric) as mp3 at 64 kbps! 10x compression rate! This is super important as streaming video+audio makes for ~82% of total internet traffic!
Lots of ideas we've already seen in previous paper overview videos such as VQ-VAE, VQ-GAN, and AudioGen applied to the problem of audio compression.
