Audio restoration and stem separation
It can bring back clarity without making everything sound too artificial or overprocessed. Stem separation is also surprisingly clean.

Split Stems with SAM Audio on Full Songs
SAM Audio is Meta's prompt-based audio separation model. Instead of being limited to fixed stems only, it can isolate sounds described in text prompts, like specific instruments, textures, or effects.
Neural Analog applies Meta's SAM Audio to full songs in stereo, and combines it with specialized models like BS Roformer, MelBand Roformer, and MDX23 for reliable quality.

Where SAM Audio Beats Traditional Stem Splitters
Extract Distorted Voices
Traditional models often struggle to isolate heavily distorted or processed vocals. SAM Audio is notably stronger on these challenging voice separations.
Remove Specific Noise
Do surgical edits by removing one precise SFX class, like barking or laughing, while keeping the rest of the scene intact.
Isolate Same-Family Instruments
Separate lead or solo guitar from rhythm guitar, even when timbres overlap and classic stems are too coarse.
Remove Rare Instruments
Target unusual percussion and niche instruments that standard preset-based models usually miss. SAM Audio is the model to test first for these rare cases.
Restore your stem from mp3 to 20Khz WAV
Stem extraction often contains mp3 artifacts and is limited to 16Khz. Improve the resulting stem using our audio restoration model.

MP3 and CD audio restoration
Does amazing job in restoring Audio from bad quality MP3s and badly extracted audio from CDs. Always my go to for audio restoration.
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.

Restoration and mastering
The flash upscaler mixed with the composite mix system makes it super easy to get closer to a song master that I'm happy with
I've been loving the app. The audio restoration works amazing on my suno songs

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.

Frequently Asked Questions
What is the difference between Neural Analog and the SAM Audio playground?
The public SAM Audio playground is for short mono experiments. Neural Analog puts SAM Audio inside Studio so you can import full songs, preserve stereo pipelines, select source regions, and download the resulting stems.
Start from SAM Audio Online if you want prompt-based extraction, or use the general stem splitter for standard vocals, drums, bass, and custom prompts.
How long does processing take?
Processing time depends on the operation, selected model, input length, and queue load. Short jobs often finish in about a minute, while long tracks, batch jobs, and heavier models such as SAM Audio Large or UniverSR can take several minutes or more.
You can leave the page and come back later. Finished imports, restorations, masters, and stems stay in Studio, where you can reopen the project and download the result.
Can an AI stem splitter isolate instruments?
To isolate a specific instrument, open SAM Audio Online, choose the custom prompt option, and describe the sound you want to isolate. Prompts such as "saxophone," "synthesizer," or "electric guitar" create a matching stem and a stem containing the rest of the mix.
Sounds that overlap heavily can bleed between stems. For a difficult section, open the track in Studio and mark the time span where the target sound is easiest to hear. You can start from SAM Audio Online or the Universal Stem Splitter.
How do I download all stems?
Click the Export button, then choose Download all current stems.
This downloads the stems currently visible in your project, using whatever version is selected for each stem. For example, if your vocal stem is set to a restored version and your bass stem is set to the original version, the export will include those current versions.
To change what gets exported, first select the version you want on each stem waveform, then click Export again.
If you need to create stems first, use the Universal Stem Splitter or open the project in Studio.
