Products

Selected offerings — the AI products recorded here, not the vendor's full catalogue.

• Gaudio Studio Application Sold on its own

  Online AI vocal remover and stem splitter for making karaoke tracks and removing background music, billed in credits.

• Gaudio Studio Pro Application Sold on its own

  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.

• Gaudio Developers API service Sold on its own

  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.

• Gaudio Sing API service

  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.

• Just Voice 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.

• Gaudio Music Placement Application Sold on its own Demonstrated, not sold

  Uses AI to select and place music that matches video dialogue and scenes.

Inside Gaudio Studio Pro

• DME Separation API service Included with the parent

  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.

• Gaudio Dub Application Paid add-on to the parent

  Gaudio Dub uses AI to generate dialogue in a target language for dubbing.
