AEScripts StemSplitter v0.0.1 Script for After Effects Windows Macintosh Full Version Free Download

AEScripts StemSplitter v0.0.1 is an audio separation tool developed by vogeledits for Adobe After Effects and Premiere Pro. It allows editors to split a complete music track into individual audio stems, including vocals, drums, bass, guitar, piano and other instruments.

Instead of using an external audio application or uploading music to an online separation service, StemSplitter integrates the process directly into the video editing workflow. Users can select an audio clip on their timeline and separate its components with a single click.

The tool is particularly useful for video editors, motion designers, music video creators and content producers who need greater control over the audio used in their projects.

What Is AEScripts StemSplitter?

StemSplitter is an audio source-separation tool that uses AI-powered processing to identify and isolate different musical components within a recording.

A finished song typically combines multiple elements, including vocals, percussion, bass instruments and melodic instruments. When these elements are mixed into a single audio file, adjusting one component independently can be difficult.

StemSplitter addresses this by generating separate audio tracks from the original recording. This allows editors to work with individual musical elements without needing access to the original multitrack recording session.

The generated stems are automatically placed on the editing timeline and aligned with the original audio.

Key Features of AEScripts StemSplitter

1. One-Click Separation into Six Audio Stems

StemSplitter can separate a song into six individual audio components:

Vocals: Isolates the main vocal performance and singing.
Drums: Separates percussion and rhythmic elements.
Bass: Extracts bass frequencies and bass instrument parts.
Guitar: Isolates guitar components within the recording.
Piano: Separates piano-related musical content.
Other: Contains remaining musical elements that do not belong to the other categories.

This six-stem workflow provides more flexibility than simple vocal and instrumental separation.

2. Direct Integration with After Effects and Premiere Pro

One of StemSplitter’s main advantages is its integration with Adobe’s video editing applications.

Rather than exporting audio to another program, processing it separately and importing the resulting files manually, users can initiate separation directly from their existing editing timeline.

The plugin is designed to work inside both After Effects and Premiere Pro, making it useful for projects that move between the two applications.

3. Automatic Timeline Organisation

After processing, StemSplitter places the generated audio stems on separate tracks or layers.

The individual stems are aligned with the original recording, preserving their timing and making it easier to work with them immediately.

The original audio is switched off rather than deleted, allowing users to retain the source recording and compare it with the separated components.

In After Effects, the generated stems appear as six separate audio layers beneath the original audio layer.

4. Local Audio Processing

StemSplitter is designed to process audio locally on the user’s computer rather than uploading recordings to an online separation service.

This is particularly relevant for editors working with unreleased music, client recordings, commercial projects or other audio that should remain private.

Local processing also eliminates the need to upload files repeatedly or depend on an external website for each separation task.

5. No Monthly Subscription for Stem Separation

The product is offered with a one-time purchase model rather than a recurring monthly subscription.

According to the developer’s product comparison, the software runs locally and does not impose additional per-clip separation charges or monthly processing limits.

This can make it useful for editors who regularly work with music and need to separate audio components across multiple projects.

6. Support for Multiple Audio and Video Formats

The original v0.0.1 release introduced audio stem separation for common audio formats.

Supported formats include:

WAV
AIFF
MP3
FLAC

The subsequent v0.0.2 update expanded support to additional audio and video formats, including MP4, MOV, MKV, OGG, M4A and AAC.

This allows users to separate audio from supported video clips as well as standalone music files.

StemSplitter supports the following Adobe applications:

Application	Supported versions
