Gaudio Studio Pro: AI Content Localization

Get Dialogue/M&E Separation, Dubbing, Subtitles, Music Replacement, and Cue sheet in one place

Image

Gaudio Studio Pro (GSP) is a cloud-based AI content localization solution that transforms premium video content—such as films and TV shows—into formats ready for export and global distribution. It automates dubbing, subtitle generation and synchronization, music replacement, and cue sheet creation using advanced AI technologies. Even when only a master file is available without separate dialogue, music, or effects (D/M/E) tracks, GSP enables high-quality localization. This allows you to bring your entire content library to the global market with efficiency, high quality, and cost-effectiveness.

Making the impossible possible!

“Is this really possible?” Previously, without D/M/E stems, music replacement, editing, and dubbing – essential for content localization – were nearly impossible. Now, they can be done cleanly and seamlessly—creating new opportunities to repurpose and enhance existing content.

The audio quality exceeded expectations

Traditional manual workflows relied on a limited music library and the editor’s memory to find replacement tracks. Now, AI instantly selects the most suitable track from a vast database of tens of thousands of songs. The result? Not just convenience, but an incredibly accurate match. Plus, instead of AI-generated music, only high-quality tracks composed by real artists are used—ensuring premium sound quality. Even better, the AI replicates mixing and mastering just like a professional remastering engineer would, delivering a seamless and natural result.

Up to 99% cost savings

Compared to traditional manual workflows, we saw up to 99% cost savings. When factoring in communication and management costs of outsourced production, the financial impact is even more remarkable. Honestly? We’d still use it even at a higher price!

Months-long process now takes just days!

Using the traditional process, it took over a month to replace music in a 60-minute video. * DME separation, music replacement, video editing, subtitles, dubbing, and review… * Multiple vendors were involved, and a single delay in any step could extend the timeline endlessly. Now, AI handles everything automatically—all in one place. Time is no longer a limiting factor. In many cases, music replacement was impossible without existing DME stems. Now? It works like magic. In today’s fast-paced content market, this ensures you never miss the golden window for global distribution.

Finally working collaboratively thanks to the GSP Web Editor

I love how the Editor lets our team collaborate in real time! The timeline-based comments and built-in content management make version control a breeze. It’s amazing how much faster we can finish projects now—what used to take months only takes days, and the quality is still top-notch.
