Guide
Learn how to use InSplitter for professional audio separation, from upload to download in four simple steps.
Quick Start
A short workflow for clean vocal and stem separation.
Choose a mode
Open the workspace and pick the mode that matches your goal. You can remove vocals, isolate vocals, split full stems, or process supporting audio tasks.
- •If you are unsure where to begin, vocal remover is the most common starting point.
- •Video files can also be processed with audio modes because the service extracts the audio track automatically.
Upload your file
Drag your audio or video file into the upload area, or click to choose a file from disk. Most common media formats are supported.
- •Higher-quality source files usually produce better stems. WAV or high-bitrate MP3 works best.
- •Confirm your file format and size before upload to avoid failed jobs.
Wait for AI processing
After upload, the AI engine starts analyzing and separating the track automatically. Processing time depends on duration, complexity, transcoding, and queue load.
- •Keep the page open while the task is running.
- •The status indicator updates as the job moves through each stage.
Preview and download
When processing completes, preview each separated track and download either individual files or the full bundle.
- •Results are stored for 24 hours, so download them promptly.
- •Use the built-in player to compare stems before exporting.
Supported Formats
Upload most major audio and video formats without conversion first.

Separated results are exported as WAV files at 44.1kHz / 16-bit so you can keep high-quality tracks for editing and remix work.
Best Practices
Follow these recommendations for cleaner, more reliable separation.
Use high-quality source files
Lossless files or high-bitrate MP3s usually give the most stable separation.
Avoid heavily compressed audio
Low-bitrate files can introduce artifacts that make stems less clean.
Choose the right mode
Select the mode that fits your goal so the workflow and output match what you need.
Check copyright before use
Make sure you have the right to process and reuse the source material.
