VocalRemover is an online service that utilizes artificial intelligence to isolate vocals and instrumentals from any given song. The platform allows users to upload various audio and video file formats, including .wav, .mp3, .flac, .ogg, .opus, .mp4, .mkv, .avi, and more. Once a file is uploaded, the AI processes the audio to separate the vocals from the instrumental tracks. The result is two separate outputs: a karaoke version (instrumentals only) and an acapella version (vocals only).

VocalRemover is designed for fast conversion while maintaining high-quality, lossless sound. Different pricing tiers are available that provide different storage capabilities and file upload limits.

StemRoller offers a user-friendly method to isolate audio components within any song. Users can initiate the process by simply entering a song title into the search interface. The application then locates the specified song online and utilizes artificial intelligence to divide it into distinct stems: vocals, drums, bass, and the residual musical elements.

Complementing the individual stem separation, StemRoller automatically generates a comprehensive instrumental track by merging all the non-vocal stems. This tool is built upon Facebook's advanced Demucs AI research project, making sophisticated audio source separation accessible as a completely free and open-source desktop application. It facilitates the creation of karaoke versions or the extraction of specific instrument tracks for various audio projects.
