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 a song into stems and isolate the sound you need
Upload a full song. Choose vocals, drums, bass, guitar, or another preset. For a custom stem, describe the sound you want to isolate.

Hear the Stem Separation Before You Start
Use SAM Audio when you need to describe a custom sound. For common stems, try a specialized preset such as BS Roformer , MelBand Roformer and MDX23 . Compare the examples because every mix separates differently.

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.

Production workflow
Neural Analog has been a godsend to me and my workflow, such a game changer. I'm more thankful than words can express, I don't know what I would have done without it.

What You Can Do with Separated Stems
Rebalance a Mix
Turn vocals, drums, bass, or another part up or down before remixing and mastering.
Build Remixes and Mashups
Create clean acapellas for mashups, extract instrumentals for seamless transitions, and break down tracks into building blocks.
Create Backing Tracks
Generate high-quality instrumental tracks for karaoke, isolate dialogue, or remove unwanted elements from podcast recordings.
Practice and Transcribe
Learn songs by isolating individual instruments, practice along with drumless tracks, or transcribe complex parts.
Restore a compressed stem before export
Stem separation can expose compression artifacts or missing high-frequency detail. Compare the extracted stem with a restored version before you continue.

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.
Isolate the part you need from a full song.
Choose a preset or describe a custom sound. Preview both stems before you download.
