Upscale Audio Quality (Super-Resolution)
Audio low-bitrate, muffled or low-sample-rate is missing its high frequencies. Audio super-resolution rebuild that missing top end, making the recording sound fuller and more detailed.

The model predicts the high-frequency content that a band-limited recording lost, extending it toward full 48 kHz bandwidth — like upscaling a low-resolution image, but for sound.

It predicts plausible high-frequency detail from patterns it learned, so the result sounds fuller. It's an informed reconstruction, not the original lost information.
Speech that is clear but dull or band-limited upscales beautifully. Heavily distorted or noisy input should be cleaned first with the relevant tool.
Sun yi kama. Super-resolution na dauke da duk wani abu da zai iya zama da wahala; kayan aikin faɗaɗa bandwidth an yi shi musamman don sauti mai tsayi da tsayi da ke da darajar waya.
Yes - since the top octave is generated, harsh or noisy source can produce a slightly synthetic shimmer or over-bright sibilance. Clean, dull speech upscales most convincingly.
The model extends content towards full 48 kHz bandwidth and returns a 48 kHz file, so even a narrowband or low-sample-rate source comes back at full resolution.
It rebuilds the actual high-frequency audio, not just the container settings, so the result genuinely sounds fuller rather than being a re-encode of the same muffled content at a bigger file size.
Yes - super-resolution will happily reconstruct and brighten any hiss or noise along with the voice, so remove noise first for a cleaner, more natural top end.
