I've been loving the app. The audio restoration works amazing on my suno songs
Restore Voice Notes:
Improve Voice Clarity.
WhatsApp compresses sounds to low quality mp4 or mpeg files to save storage space. Remove noise and improve voice clarity online with Generative Neural Networks.

How It Works
Import Audio
Upload your WhatsApp voice note (MP4, MPEG, OGG, M4A, or MP3) or a podcast recording.
Neural Reconstruction
The AI model removes background noise and rebuilds the lost voice clarity caused by heavy compression.
Download WAV
Export a crystal clear, restored high quality WAV file of your voice recording.
Restore voicemail and low-quality voice notes
Remove heavy compression artifacts, background noise, and muffled sounds from WhatsApp voice notes.
Example: Voicemail ASMR Restoration
Clean up podcasts and speech recordings
Transform amateur speech recordings or heavily compressed podcast files back to studio-level clarity.
Example: Podcast Quality Restoration
Remove background noise and restore voice tone
Use stem splitting to separate vocals from background noise, the NovaSR upscaling model to generate missing frequencies, and Match EQ to restore natural tonal balance.
Example: Voice notes with heavy distorsion, phone recording, and background noise

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

How does the Voice Restoration model work?
Speech Recognition Structure
The model is trained on thousands of hours of clean, high-resolution human speech and their degraded counterparts. It understands phonetic pronunciation and vocal traits.
Noise Separation
By analyzing the temporal domain, the algorithm separates unwanted background frequencies from the core vocal recording.
Voice Clarity Optimization
Outputs are optimized to enhance intelligibility. The result is a richer, closer, and much clearer vocal output, eliminating phone microphone tinny sounds.
Frequently Asked Questions
Yes. Humans hear frequencies between 20Hz to 20Khz. 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.
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.
That's okay! Restoration is not a silver bullet. Neural Analog offers other tools such as stem splitting and mastering to power your music creation. This enables a hybrid production workflow where you can replace low-quality AI elements entirely.
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.
You can Restore Audio for free on a sample. The models run on beefy GPUs, so for longer audio, you'll need a paid subscription.
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.
Don't settle for muffled voice notes.
