I've been loving the app. The audio restoration works amazing on my suno songs
Improve Phone Call Recordings:
Restore Clearer Speech with AI.
Restore clearer phone call audio for better playback, transcription, analysis, and voice AI training.
SELECT RESTORATION TYPE
Upload audio files
Drag & drop or click to browse (multiple files supported)
Supports: MP3, MPEG, MP2, MPGA, WAV, WAV, AIFF, AIF, AIFF, AIF, FLAC, AAC, OGG, OGA, OPUS, M4A, MP4, WEBM, WMA, ALAC, AMRMax size: 50MB.
How It Works
Upload Call Audio
Import one or multiple recordings in MP3, WAV, M4A, OGG, AAC, or other common speech formats.
Restore Speech Clarity
Use the Speech Upscaler model to reduce compression artifacts, rebuild missing detail, and improve intelligibility in low-quality phone recordings.
Download Restored Audio
Export a cleaner, fuller WAV file for playback, transcription, analysis, or voice AI workflows.
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.

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.

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.

How does phone call audio restoration work?
Speech Reconstruction
The model is trained on clean and degraded speech pairs, allowing it to restore clarity, presence, and natural vocal detail in compressed phone recordings.
Better Playback and ASR
The output is more intelligible and more comfortable to listen. That can improve playback quality and help downstream ASR (Automatic Speech Recognition) systems perform better.
Better Voice AI Datasets
Improve datasets used to train voice agents and conversational AI systems by reducing noise, compression artifacts, and missing frequency content. Leverage existing low quality data to generate high quality outputs.
Frequently Asked Questions
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.
