Once you are ready, signed-in users can upload an audio file or choose generated music from their history. Start by selecting the source that matches the project you want to examine. The separation step then turns that source into a result you can inspect in the same workflow. Keep the first pass simple: choose one recording, start the job, and wait for the result before deciding what to download. This approach makes it easier to compare the source with the separated tracks and choose the material that supports your next task. A history item can be useful when you want to revisit generated music, while an uploaded audio file gives you a direct path for a recording already on your computer. The important choice happens before processing: select the right source, confirm that it is the version you intend to use, and leave detailed listening for the result stage.

What the four stems contain
The four-stem mode returns vocals, drums, bass, and other instruments as the four separated parts of the result. The vocals track is the place to inspect lead and backing vocal material. The drums track gathers the rhythmic and percussive material that drives the arrangement. The bass track gives you a focused way to listen to the low-end part of the song. The other instruments track contains the remaining instrumental material that does not belong in the vocal, drum, or bass track. Taken together, these four stems give you a practical view of the arrangement without asking you to treat every sound as a separate output. You can listen to each part on its own, compare it with the source, and decide which element is useful for the task in front of you. For a remix, that may mean concentrating on a rhythmic section; for practice, it may mean listening closely to one part while the rest stays out of the way. The output is organized around these four categories, so plan your next step with that structure in mind.
03
Review and download the result
When the result is ready, users can preview individual separated tracks and download them individually. Listen before downloading so you can check the passages that matter to your project, then keep only the tracks you need for the next step. Individual downloads keep the review process flexible: you can compare a vocal passage, check a drum entrance, or bring one selected track into another part of your workflow without treating every output as a finished arrangement. A ZIP archive download is available to users with an active subscription or purchased credit pack. Use the individual option when you want a focused handoff, and use the archive option when that account qualification fits the way you want to collect the result. In either case, previewing first gives you a chance to hear the material and organize the files around the task you chose.

Ways to work with separated tracks
For practice, use a preview to focus on the part you are studying and return to the source when you need context. For remixing, audition individual tracks and download the elements that help you test a new balance or arrangement. For karaoke preparation, listen through the vocal and instrumental material before deciding how you want to rehearse. Separated tracks can also support backing-track preparation: review the musical parts, identify the section that fits your performance, and keep the download that belongs in that setup. Sampling work benefits from the same deliberate review. Listen for a short passage, compare it with the surrounding material, and decide whether the selected track gives you a useful starting point. These are different creative goals, but they share one practical habit: preview the material first, then download only what serves the next action. Naming files by project and purpose can make those choices easier to revisit later, especially when you are comparing more than one source.
05
Check formats, duration, and credits first
The upload accepts MP3, WAV, M4A, and OGG files. Keep uploaded files smaller than 50 MB so the source fits the file-size boundary. For signed-in stem-splitter jobs, audio can be up to 10 minutes, so check the duration before you start a job. The estimated and charged cost is 5 credits for each started five-minute interval; use that interval as the planning unit when you consider a longer recording. Processing results vary by source, arrangement, and the material in the recording. Quality varies, and artifacts are possible, so leave time to preview the returned tracks before you decide how they fit your project. A dense passage, overlapping sounds, or a source with a lot of competing material may need closer listening than a simple section. If the first result does not suit the task, compare several representative passages and make a careful choice about which separated track to carry forward. Staying within the accepted format, size, and duration limits gives you a clear starting point for that review.

Audio rights and practical FAQs
What should I confirm before working with a recording?
Confirm that you have permission to work with the audio and that your planned use follows the terms that apply to the recording. Keep that decision separate from the technical step of splitting the file.
How do I choose between possible sources?
Choose the version that matches the work you want to examine, and keep the original available for comparison. A clear source makes it easier to understand what you are hearing in the result.
How should I review a separation?
Listen to more than one passage, including a busy section and a quieter transition. Compare what you hear with the source and decide whether the track is suitable for the next step you have in mind.
Can I treat every result as final?
Treat a separation as a working result to audition. Source material affects what remains in each track, so review the sections you plan to use and keep the original nearby for context.
How can I keep a project organized?
Group downloads by the task they support, such as practice, remixing, karaoke preparation, or backing-track work. Clear names make it easier to return to a decision without listening through every file again.
What is a sensible next step after review?
Keep the track that serves your immediate goal, note any passage that needs another listen, and preserve the source alongside the selected download. This keeps creative judgment visible instead of treating the first listen as the whole answer.
