End Boost: AI Audio Mixing Software for Video Editors
End Boost uses AI to automatically mix and master voice, music, and sound effects for video projects, delivering pro-quality audio without any mixing expertise.
Overview
End Boost is a standalone desktop application that takes the guesswork out of audio post-production for video creators. Powered by the AI algorithms of Alex Audio Butler, it automatically balances and masters voice, music, and sound effect tracks using intelligent presets, applying volume curves, compression, limiting, and ducking in seconds rather than hours. This means editors who have zero audio engineering background can still output broadcast-ready sound that rivals professional mixes.
Designed to slot into any existing workflow, End Boost works alongside any NLE or DAW that supports WAV import and export, including Premiere Pro, DaVinci Resolve, Final Cut Pro X, and Vegas. With over 25 smart preset combos covering different content styles, plus built-in AI de-noising and mastering, it's a dedicated tool for creators who want their videos to sound as polished as they look, without spending time learning complex audio software.
