AI audio upscaler and restoration

Yes. If the source is MP3 or otherwise degraded, upscale or restore the sample before time-stretching, pitch-shifting, saturation, or heavy effects. That reduces artifact amplification later in production.

Start with MP3 to WAV upscaling, then download the restored file from Studio for use in your DAW.

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 random noise. It can reduce compression artifacts while rebuilding harmonic content above the damaged bandwidth of the source.

Start with MP3 to WAV upscaling for general music cleanup, or use Audio Restoration to compare multiple restoration models.

You can test MP3 upscaling on short samples for free. Full tracks and stems use processing minutes because the models run on GPUs. Subscribers get included monthly processing minutes, and you can also buy extra processing minutes.

Try the MP3 to WAV upscaler, then check plan limits before running large batches.

Many AI-generated tracks sound capped or artifacted because training data and platform exports often include lossy compression. The model can learn bandwidth limits, swirly highs, brittle cymbals, and other MP3 artifacts.

Use MP3 to WAV upscaling or Audio Restoration to reduce artifacts and rebuild missing high-frequency detail before mastering.

It can help when the stem sounds muffled because it lost high-frequency detail during compression or separation. Run restoration on the stem before heavy effects, pitch shifting, or layering.

If the problem is low-end muddiness, masking, or a bad stem balance, use EQ, volume, or another stem split in Studio instead of expecting upscaling to fix the mix.

Yes, restoration can work on old codecs and low bit-depth audio after the file is decoded into an audio signal. Results depend on how much usable information remains in the source.

Try a short sample with Audio Restoration. For retro game and sound-effect material, see the UniverSR sound effects guide.

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 44.1 kHz-or-lower sources at 44.1 kHz.

For the model-level details, read the UniverSR sample-rate guide or compare models in the restoration docs.

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.

Do this in Studio by selecting the restored version as the source before running another restoration. Stop when the result improves less than the artifacts it introduces.
