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

Free accounts can upload files up to 50MB.
How it works
Import Your Track
Paste a Suno link or upload the file.
Restore the Audio
Reduce metallic artifacts, harsh highs, and encoding damage thanks to specialized AI models that regenerate high frequencies
Master the Result
Use reference-based mastering for a cleaner tonal balance.

Fix the Source Before You Master It
If the track already has hiss, metallic tone, or smeared highs, normal mastering usually makes it worse. This example uses AudioSR with a 4kHz cutoff in mono to regenerate high frequencies before mastering.
Example: AudioSR restoration before mastering (4kHz cutoff, mono)
Example: Remove clipping texture and recover punch
What People Mean by "Suno Hiss"
It is usually not just hiss. What you hear is often a mix of metallic tone, AI shimmer, squeaky quality, high-pitched sound, weak transients, and a boxed-in midrange.
- Metallic or hollow vocals
- Shimmery highs and AI shimmer texture
- Squeaky quality on sustained notes
- "Aluminum can being rubbed" type top-end resonance
- High-pitched sound that feels detached from the mix
- Grainy highs and smeared reverb tails
- Boxed-in mids
- Weak drum transients
- Busy sections that collapse together
What You Can Do About It
Restore the damaged parts first, then master the cleaner file. That gives you a better chance of getting smoother highs, more natural vocals, and a mix that opens up instead of getting harsher.

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.

Frequently Asked Questions
For most songs, use this order:
- Split the song into stems if you need to fix individual parts.
- Restore or enhance the stems that need work.
- Use EQ, volume, or Match EQ to balance the stems together.
- Export the finished stem mix.
- Import the exported mix again and use Master as the final loudness step.
In other words: restore and mix first, then master the final mix.
No. They solve different problems.
- Audio restoration tries to rebuild missing frequencies, reduce compression artifacts, and improve the source quality.
- Mastering changes loudness, dynamics, and tone so the track is more polished and playback-ready.
If your file sounds compressed, old, muffled, or artifacted, restore it first. Then master the restored file.
Restoration and mastering solve different problems. Many mastering services rely on multiband compression to boost or compress existing frequencies, so mastering without restoration can amplify artifacts instead of fixing the root quality issue.
Once your audio is restored, Automatic Mastering can polish it for professional release, with intelligent loudness optimization tailored to your track.
Audio restoration analyzes spectral content and removes lossy-compression "chirps" and "warbles", replacing them with coherent harmonic content.
Yes. However, for AI-generated MP3s, you can achieve even better results by first using Neural Analog's Audio Restoration service to rebuild missing frequencies, then mastering the restored file. This two-step process gives you the highest possible quality.
The mastering process preserves your original creative intent. Your track will sound clearer, more present, and competitively loud without sounding squashed or distorted.
Free audio editors or basic volume boosts simply turn everything up, which causes digital clipping, ruins your dynamic range, and makes harsh frequencies even harsher. Streaming platforms detect this distortion and will penalize your track's quality. Proper mastering with Neural Analog does much more than just increase volume: it uses smart limiting to reach commercial loudness without clipping, applies dynamic Match EQ to fix muddy or harsh tonal balance, and can even restore missing high frequencies that AI generators leave out.
A single restoration model may not fix every problem. If the track sounds flat or weak in the low end, try a stem-based workflow:
- Split the song using the 4-stem preset.
- Select the bass stem.
- Enhance it with Neural Remix.
- Use EQ to boost or clean the low end if needed.
- Blend the processed version with the original if the result is too strong.
UniverSR is better for missing high frequencies. Neural Remix and EQ are often better starting points for bass, muddiness, or low-end problems.
If your Suno track sounds metallic, start by fixing the source.
