I've been loving the app. The audio restoration works amazing on my suno songs
Universal AI MP3 Upscaler:
Heavyweight Restoration for Music

How MP3 Upscaling Works
Import MP3 or Link
Upload tracks from a file, Suno, Udio or Producer AI.
Neural Upscaling
To upscale your MP3 and maintain detail, click the "Restore Audio" button. Our model predicts missing content.

Get a clean, high quality WAV with full 20kHz frequency spectrum.
Restore missing high frequencies
Low sample rate musics, such as old recordings or AI generated tracks, miss high frequencies. This example uses AudioSR with a 4kHz cutoff in mono.
Example: AudioSR restoration (4kHz cutoff, mono)
Remove clipping from poor recordings
Clipping happens when audio is too loud to be encoded. Use Neural Analog to remove clipping artifacts while maintaining high volume.
Example: Remove Clipping + DACVAE upscaling on old mp3 file
Upscale English speech and improve audio quality
Use Neural Analog to upscale voice tracks, singing, and speech thanks to the NovaSR model.
Example: Upscaled speech with NovaSR (mono)

Neural Analog makes me feel like a monkey with an AK-47, in the best way possible
It worked! Well done :) Many thanks :))))
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.

How GPU-Powered MP3 Upscaling Removes Artifacts
GPU-Accelerated Inference
Our heavyweight models run on high-end GPUs to predict missing audio data in seconds. It recognizes AI generation patterns.
Harmonic Reconstruction
Missing frequencies above 16kHz are rebuilt using learned harmonic relationships. The upscaled MP3 regains natural overtones.
Artifact Removal
Compression artifacts (digital chirps, warbles) are identified and removed while preserving musical transients.
Frequently Asked Questions
Yes, upscale first when your source is MP3. Upscaling before time-stretching, pitch-shifting, or heavy processing reduces artifact amplification and preserves headroom for manipulation.
Upscaling and mastering do different jobs. Upscaling reconstructs missing data and reduces MP3 artifacts, while mastering applies EQ, compression, and loudness optimization.
Always upscale MP3 files first, then master the restored WAV for professional release.
Once your audio is restored, the Automatic Mastering tool can polish it for professional release, with intelligent loudness optimization tailored to your track.
Neural MP3 upscaling reconstructs coherent signal, not noise. It removes compression artifacts while rebuilding harmonic content. The result is cleaner than the original MP3, with measurable improvement in SNR and spectral flatness.
Test MP3 upscaling on short samples for free. Full tracks and stems use processing minutes because the models run on GPUs. Subscribers get included weekly processing minutes, and you can also buy extra processing minutes.
Many AI-generated tracks sound capped and artifacted because the training data is often lossy MP3. Models learn 16kHz limits and compression artifacts from that data, and MP3 upscaling restores toward a full 20kHz spectrum while reducing learned artifacts.
Yes, upscaling can make muffled stems sound more open. Many stem splitters use a "neural audio encoder" capped at 16kHz for speed, and MP3 upscaling restores frequencies up to 20kHz before you apply effects or layering.
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.
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.
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.
Don't let MP3 artifacts limit your production.
