I've been loving the app. The audio restoration works amazing on my suno songs

How AudioSR Works
Import Audio
Upload a file or import a link from Suno, Udio, or Producer AI.
Regenerate High Frequencies
The AudioSR model predicts missing high-frequency content above your selected cutoff.
Download Restored WAV
Export a cleaner, higher-fidelity result ready for mixing or mastering.
What Is AudioSR?
AudioSR (audio super-resolution) is a reconstruction method that restores bandwidth lost by compression, low-bitrate exports, and degraded sources. Instead of boosting EQ, it estimates plausible harmonic and transient detail that should exist in upper frequencies.
The original AudioSR research paper is AudioSR: Versatile Audio Super-resolution at Scale. You can also browse examples on the official project page.
Run the AudioSR audio upscaler in the browser UI without local setup, GPU configuration, or manual pipeline scripts. Restore old and damaged music recording.
AudioSR Example: Regenerated High Frequencies
Compare the original and AudioSR restored versions. Notice how upper-band detail is reconstructed while keeping low frequencies stable.

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

Why Use This Audio Upscaler?
Model-Based Regeneration
AudioSR does not just amplify highs. It reconstructs probable high-frequency structure from learned audio priors.
Cutoff-Controlled Audio Restoration
Choose your frequency cutoff and regenerate only the upper spectrum while preserving lower bands from the source.

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. For full tracks and stems, paid subscriptions cover GPU processing costs.
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 restores audio to 48Khz. The 'Music Upscaler' restoration algorithm keeps 48Khz sources at 48Khz, 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.
