Stem Splitter

Separate Vocals, Instruments, and Beats with ACE Studio's New AI Stem Splitter

Isolating vocals, extracting clean drum loops, or separating instrumental layers from a finished track no longer requires expensive software or complex workflows. With the ACE Studio Stem Splitter, musicians, producers, and creators can efficiently break down full songs into usable components - all with studio-grade clarity and control. You can test the tool directly in your browser, without installation or setup. For unlimited access and full integration with the ACE Studio production environment, the Stem Splitter is fully embedded within the desktop app - no file conversions, third-party plugins, or friction.

How to Use the AI Stem Splitter – Step-by-Step

Get Started
Using ACE Studio’s Stem Splitter is quick and intuitive, even if you’ve never worked with isolated stems before. The tool is directly embedded within the ACE Studio interface and designed to deliver clean, labeled audio layers with minimal setup. Here’s a step-by-step breakdown:
1

Step 1: Drop Your Track into ACE Studio

Start by launching ACE Studio and opening a new or existing session. Add or drop your audio file into the workspace. You can upload MP3, WAV, or FLAC formats without needing to convert or reformat the track beforehand. Once the file is loaded, it appears in your session timeline as a standard audio track.

2

Step 2: Launch the Stem Splitter Tool

With the track selected, click on the Stem Splitter icon located in the track header or use the right-click menu to access the feature. The splitter panel will open, displaying a preview of your file and options for customizing the separation.

3

Step 3: Adjust Your Split Settings

Inside the Stem Splitter window, select how many stems you want to extract: vocals, drums, bass, and others. You can also check a box to enable vocal cleanup, which attempts to remove reverb and backing vocals from the isolated vocal stem. These settings let you tailor the split to the material you’re working with, which is especially useful for complex or layered mixes.

4

Step 4: Start the Splitting Process

Once your settings are in place, hit Start Split. The processing begins immediately and usually finishes within a few seconds, depending on track length. Each stem is placed on its own track and labeled by type for easy identification.

5

Step 5: Export or Use in Projects

You can now solo, mute, or rearrange individual stems directly in the ACE Studio environment. They function just like any other track in your session, meaning you can apply effects, timing edits, or arrange them freely. If needed, you can also export each stem for use in an external DAW or collaboration workflow. Your original track remains unchanged unless manually edited, allowing you to keep full control and flexibility over your project.

What You Can Do with ACE Studio AI Stem Splitter

ACE Studio's Stem Splitter is more than a utility, it's a precision tool that fits directly into your creative environment. Built to support real-world production demands, it allows you to isolate, manipulate, and reuse parts of any audio track with ease and accuracy. You can rework existing material or build something new from layers of sound — here's how the splitter enhances your process.

Split Songs in Seconds with Lightning-Fast Processing

Unlike tools that require external uploads or long queue times, ACE Studio processes your files directly in-browser using optimized background threading. This delivers rapid separation with minimal latency. From import to result, most splits complete in under 10 seconds for standard-length tracks.
This speed keeps your creative flow intact — from quickly sketching out an idea to prepping stems for a full mix, everything stays fluid and interruption-free.

Upload MP3, WAV, and FLAC — No Conversion Needed

ACE Studio supports lossless and compressed formats equally. MP3, WAV, and FLAC files are accepted without the need for conversion, and all internal processing is handled in high resolution to preserve sonic quality.
This is particularly useful when working with varied source material, such as demos, field recordings, legacy tracks, or reference mixes. You can import them as-is, and the splitter will adapt dynamically to the input characteristics without requiring manual adjustments.

Integrate Seamlessly with ACE Studio Tools

Stem separation is fully embedded within ACE Studio's modular architecture. Once the stems are generated, they appear as editable tracks in your workspace — no import steps, no external routing. From there, you can apply effects, tune vocals, harmonize melodies, and arrange parts using ACE's native toolset.
Since ACE Studio operates in a non-destructive editing environment, your original track and extracted layers remain linked. This lets you A/B between full mix and individual stems, or revert specific edits without reprocessing the entire file. You're not just getting stems — you're expanding the track's flexibility within your session.

Customize Your Split – Total Control

Not every project needs complex multitrack editing. ACE Studio is designed to help you isolate and transform vocal content quickly and effectively. Whether you're working on a mashup, a backing track, or a quick demo, ACE keeps things streamlined so that you can stay creative without distractions.
This focused approach helps reduce prep time and is ideal for creators who want fast, polished results without diving into manual audio separation or editing.

Instantly Extract Vocals, Drums, Bass & More

With one upload, the Stem Splitter automatically detects and separates lead vocals, drums, bass, harmonic elements, and background layers. Each element is processed to retain its musical integrity, so you're left with stems that are ready for reassembly or standalone use. This opens up clean access to the core of any composition — ideal for remixing, rebuilding arrangements, or building stems for live sets.
The tool's intelligent processing ensures phase alignment and timing accuracy across all stems, so they remain perfectly synced when recombined in ACE Studio or another DAW.

Try the AI Stem Splitter

Isolate vocals, prepare stems for mixing, or reshape arrangements — ACE Studio's AI Stem Splitter gives you the flexibility to create without limits, directly in your browser.

Try It Once Directly in Your Browser

Curious to see how it works? You can test the splitter once for free, right in your browser — no installation or login required. This hands-on demo gives you full-quality output for a single track and lets you experience the speed and accuracy of AI separation before committing further.

Internally, audio is processed in high resolution to preserve the integrity of each extracted stem.

How long does it take to process a track?

Processing time depends on the length and complexity of the track, but in most cases, the stem splitting is completed in under 10 seconds for songs up to 4–5 minutes long. The system is optimized for real-time workflows, ensuring that you can get your stems quickly without interrupting your creative process.

Do I need to create an account?

Yes — an ACE Studio account is required to access the platform's tools and features. Creating an account is free and only takes a minute.
Once you're logged in, you can explore the interface, try available demos, and manage your projects. A subscription is only needed if you want unlimited access and advanced functionality.

Is the Stem Splitter available without a subscription?

Yes — you can try the Stem Splitter with one song for free, but you'll need to be logged into your ACE Studio account to access the demo.
For unlimited stem separation and full integration with other tools, an active subscription is required.

Can I use the stems for commercial projects?

Yes — if the original track is your own composition, or you have explicit rights to use it, then you can use the extracted stems for any purpose, including commercial releases, sync licensing, monetized content, or live performances.
However, if you split a song that is protected by copyright and you do not own the rights, the resulting stems are still subject to copyright restrictions. ACE Studio does not grant any additional rights to use third-party material commercially. It is your responsibility to ensure that your usage complies with applicable copyright laws.
If you're working with your own original music, there are no restrictions on how you use the output.

What audio elements can be extracted?

The Stem Splitter can isolate lead vocals, drums, bass, harmonic instruments (e.g., piano, guitars, synths), and residual elements such as background effects or ambiance. Each component is separated into its own audio layer, giving you full control over how the song is reconstructed or repurposed.

Can I remove vocals from any song?

Yes, in most cases. The splitter can effectively extract vocals from the vast majority of studio-mixed tracks. However, results may vary slightly depending on how the original song was produced, particularly with lo-fi mixes, mono recordings, or tracks with heavy vocal effects or distortion.

Will my audio files be stored or shared?

No. ACE Studio does not store or share your audio files after processing. Uploaded tracks and generated stems are held temporarily for the duration of your session and are then deleted. User privacy and data integrity are key priorities, and all file handling is governed by secure, GDPR-compliant infrastructure.

Who is the AI Stem Splitter designed for?

The tool is built for music producers, vocalists, remix artists, sound designers, DJs, and hobbyists alike. Use it to prepare clean vocals for a mix, create karaoke tracks, sample drum loops, or build live sets from pre-existing music — the stem splitter adapts to your creative needs with no advanced technical skills required.

What does a stem splitter do?

A stem splitter analyzes an audio file and breaks it down into individual components (stems) — typically vocals, drums, bass, instruments, and other layers. This lets you manipulate parts of a song independently: mute vocals, isolate drums, rearrange structure, or remix freely using only the elements you need.

How do I split the stems of a song?

Simply open ACE Studio, drag your audio file into a session, and activate the Stem Splitter tool from the track header. Choose which stems you want to extract, fine-tune your settings, and hit Start Split. In seconds, you'll see each stem appear on its own track, ready to be edited, exported, or used in your production.

Will it work on older or low-quality recordings?

Yes. While output quality always depends on the source, ACE Studio's Stem Splitter is optimized to handle noisy, compressed, or vintage audio. It can often isolate vocals, reduce background bleed, and improve clarity even in imperfect recordings.
