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

How to Improve Video Audio Quality
Upload Your Video
Import an MP4 video or an audio file from your edit.
Extend Speech Bandwidth
The page opens with the NovaSR preset selected. Use it for speech-heavy video where compression, phone mics, or bandwidth limits have removed vocal presence and consonant detail.
Export Cleaner Sound
Download the improved audio, or export an MP4 with the enhanced audio track when your source is an MP4 video.
Fix the Audio Problems That Ruin Otherwise Good Video
Restore Missing Speech Frequencies
Rebuild upper-band speech detail lost to phone recordings, meeting compression, screen recorders, and social-platform transcodes.
Make Voices Easier to Understand
Improve dialogue, interviews, courses, vlogs, screen recordings, meeting clips, and phone videos where voices sound thin, muffled, or narrowband.
Improve Compressed Speech
Enhance speech recordings that have been damaged by low-bitrate codecs, old camera audio, messaging apps, or webinar platforms.
Repair Compressed Video Audio
Improve video clips that were compressed by messaging apps, screen recorders, social platforms, or old cameras.
Rebuild missing high-end detail in speech
Phone calls often lose upper frequencies through bandwidth limits and compression. Restoration models can regenerate part of that missing spectral detail to improve consonants, vocal presence, and overall clarity.
Example: Narrowband Phone Call Restoration
Make recorded voices sound like a professional podcast
Improve zoom call recording quality by reducing codec artifacts and restoring speech presence. Voices sound clearer and more natural.
Example: Compressed Speech Reconstruction
Improve recordings for transcription and analysis
Restored audio can help ASR (Automatic Speech Recognition, systems that convert speech to text) perform better and reduce listening fatigue for QA, compliance, interviews, research, and investigative analysis.
Example: Restoring compressed call audio with noise and distortion
Better audio for call centers, interviews, and voice AI datasets
Leverage existing low quality phone call recordings to create better voice datasets. Train better voice agents and conversational AI models by providing cleaner, more intelligible speech inputs.
Example: Multi-speaker Call Clarity Improvement
Built for Creators Who Care About the Audio Track
Bad video sound makes people leave faster than imperfect visuals. Neural Analog focuses on the speech signal itself: missing high-frequency detail, narrowband voices, compression artifacts, dialogue clarity, reverb, clipping, and codec damage.

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.

I love the interface. I love the bulk upload/download features. They’re a life saver! Also I just realized that Apollo is magic and I don’t even need to use denoise. Apollo somehow removes noise much more naturally. So I’m actually spending way less credits than I expected.

Why NovaSR Instead of a Basic Noise Filter?
Speech Bandwidth Extension
NovaSR is designed to extend speech bandwidth and restore missing vocal detail, not just subtract background noise.
More Presence in Narrowband Voices
Phone mics, meeting apps, and low-bitrate video often remove the frequencies that make consonants and vocal presence clear. NovaSR rebuilds part of that lost structure.
MP4-Friendly Export Workflow
Improve the audio track, download enhanced audio, or export an MP4 with the restored sound when the original upload is an MP4 video.
Frequently Asked Questions
Are high frequencies even audible?
Yes. Humans hear frequencies between 20 Hz to 20 kHz. Low quality audio hardware, like smartphones, can easily play these frequencies.
Unfortunately, hearing degrades with age and with exposure to loud sounds. For example, the famous ultrasound "Mosquitone" (17.8kHz) is clearly audible to younger people, but notoriously difficult to hear for adults.
However, even if not directly heard, high-frequency content is crucial for the transient response and "spatial feel" of audio, which impacts how you perceive quality even if you don't consciously hear a sine wave at that pitch.
I prefer the original to the restored audio
That can happen. Restoration is most useful when the problem is missing bandwidth, clipping, hiss, or lossy-compression artifacts. If the original already has the tone you like, keep the original version in Studio and compare it with the restored version before downloading.
Open full answerIf the problem is arrangement, bass balance, a specific noisy layer, or one bad instrument, try stem splitting, EQ, Match EQ, or mastering instead.
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.

Is audio restoration free?
You can restore audio for free on a sample. Full files use processing minutes because restoration runs GPU models. Your included processing minutes are used first, then any extra processing minutes.
Open full answerPlan limits and included minutes are listed on the pricing page.
Does it work for old codecs like WMA or low bit-depth 8-bit audio?
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.
Open full answerTry a short sample with Audio Restoration. For retro game and sound-effect material, see the UniverSR sound effects guide.
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 44.1 kHz-or-lower sources at 44.1 kHz.
Open full answerFor the model-level details, read the UniverSR sample-rate guide or compare models in the restoration docs.
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.
Open full answerDo 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.
