How UniverSR Works

Import Degraded Audio

Upload music, archival recordings, retro game sounds, foley, or sound effects.

Run UniverSR

The model reconstructs missing high-frequency and transient detail from low-bandwidth or damaged sources.

Download Restored WAV

Export a cleaner 48kHz result ready for editing, mixing, archiving, or sound design.

What Is UniverSR?

UniverSR is a more powerful audio super-resolution model designed to restore missing bandwidth and detail in a wide range of audio types. It works on foley, sound effects, music, voice, and other degraded material, making it a better fit for difficult restoration jobs than narrower upscalers.

Unlike simple EQ or resampling, UniverSR reconstructs plausible upper-band content from the source itself. Neural Analog runs the model online so you can restore audio without local GPU setup, Python environments, or batch scripts.

For a concrete case study, listen to the restored RPG Maker 2000 RTP sound effects in the full UniverSR article.

UniverSR Example: Restoring Retro Foley and SFX

This RPG Maker 2000 Sword2 effect shows how UniverSR can reconstruct bandwidth and brighten old game audio without changing the underlying timing of the sound.

Wow thank you so much i upscale videos and take out live recordings from music because of my autism i hate the crowd

Amazing tool for audio. Clean, simple, and effective. I would spend hours in RX to get the same results. Give it a try. I can save you hours of production time.

Useful app besides AudioSR that needs improvement for AI vocals high frequencies restoration. It sometimes adds a straight line at 10kHz or reduces the 5-10kHz volume. I only got the right correction on my 5th restoration of the same vocal.

Why Use UniverSR Online?

More Powerful Restoration Model

UniverSR handles more than old music. It can restore foley, sound effects, damaged recordings, and other hard-to-reconstruct audio.

Built for Tough Low-Bandwidth Sources

It reconstructs believable upper-band detail on narrowband and degraded material where ordinary upscaling or EQ usually falls apart.

Run UniverSR Online

Use the high-compute model directly in Neural Analog with upload, configuration, preview, and WAV export in one workflow.

Frequently Asked Questions

How is UniverSR different from AudioSR?

UniverSR is a heavier and more capable restoration model. It is better suited to difficult degraded audio, including foley, sound effects, music, voice, and other narrowband material. AudioSR is lighter and still useful for classic high-frequency regeneration workflows, but UniverSR generally gives stronger results on harder inputs at a much higher compute cost.
What kind of audio should I use UniverSR on?

UniverSR is useful for degraded, compressed, narrowband, or old-sounding audio. It can help rebuild high-frequency detail and reduce harsh high-frequency artifacts such as hiss, brittle cymbals, sibilance, or missing brilliance.

It works on more than music: foley, retro game sounds, sound effects, voice, archival recordings, and other degraded audio can benefit.

However, it is not the best tool for every problem. Bass stems and low-end muddiness often need Neural Remix, EQ, or stem-level editing instead of high-frequency restoration.

Doesn't the restoration model just add noise?

No, it does not just add noise. Unlike enhancers that layer white noise, the generative model reconstructs the clean signal that should be there by separating useful harmonic and transient structure from compression artifacts and other degradations.
Why is UniverSR reserved to Pro users?

UniverSR is the most compute-heavy restoration model in Neural Analog. It uses much more GPU time than the standard upscalers, so it is reserved to Pro users and above for longer music, foley, and sound-effect restoration jobs.
How long does processing take?

That depends on the operation, the selected model, and your audio input length. Usually, it's about 30s. Large models on long audio can take up to 5mn. You can leave the page and come back later.
Does it work for old codecs like WMA or low bit-depth 8-bit audio?

Yes, it can work on old codecs and low bit-depth audio. Processing is based on raw signal rather than a specific codec, so trying a sample is the best way to evaluate performance.
Do you support 48 kHz upsampling?

Yes. Support depends on the model. UniverSR, AudioSR, and FlashSR upscale low resolution audio to 48 kHz (super resolution). The 'Music Upscaler' restoration algorithm keeps 48 kHz sources at 48 kHz, and restores 44.1Khz-or-lower sources at 44.1Khz.
Can I run restoration multiple times for better results?

Yes, you can run restoration more than once. You can change the selected Source to run another pass on already restored audio, and batch imports support an 'Iterative restoration' toggle that selects the latest restored version of each file.
