Karaoke Assembler

Assembles karaokes/instrumentals fast.

Karaoke Assembler is designed to help users create karaoke or instrumental videos directly within their browser. It functions as a lightweight media editor that allows you to replace the audio track of a video file with a new one (such as an instrumental version) and burn synchronized lyrics (captions) onto the final output.

Key Features

Video & Audio Mixing: Replace a video's original audio with a custom track (e.g., swapping a music video's audio with an instrumental track).

MP3 Extraction: Automatically extracts and encodes the audio from your video file into an MP3, allowing you to download it for processing (e.g., to use with external online vocal remover tools).

Captioning Engine: A simple text-based system to add synchronized lyrics that overlay the video.
