Gaudio Lab
Application
Uses AI to select and place music that matches video dialogue and scenes.
Online AI vocal remover and stem splitter for making karaoke tracks and removing background music, billed in credits.
Cloud content-localization service for films, series and short-form video: from one master file it separates dialogue, music and effects, then produces dubbing, subtitles, replacement music and cue sheets, with AI output reviewed by post-production experts.
API service
Splits a finished video's soundtrack into separate dialogue, music and effects tracks, so legacy masters can be dubbed, re-scored or cleaned without the original stems.
REST API platform selling Gaudio Lab's audio models per minute: music stem separation, speech-from-noise isolation, dialogue/music/effects separation and line-by-line lyric alignment, on credits or a monthly plan.
Karaoke engine licensed to platforms and devices: backing tracks made from original recordings by removing the vocals, real-time pitch and tempo control, AI scoring against the original singer, and automatic fill-in of vocals when the performer stops.
Developer tool
On-device AI noise suppression under 30 ms latency that strips background sound from speech, offered as an SDK for Android, iOS, Windows, macOS and Linux, a mobile recorder app and a Mac voice-enhancer app.
