Mark Rober’s CrunchLabs produces some of the most-watched educational and science videos online, reaching millions of viewers worldwide–from massive slime experiments to wild engineering challenges. But as CrunchLabs expanded globally, the team faced a familiar problem: archival content was fully mixed, making it difficult to isolate dialogue from music and effects for localization, sponsor-ready edits, or alternate versions.

With AudioShake’s music removal and sound separation technology, CrunchLabs can separate audio into dialogue, music, and effects, enabling them to unlock past content, streamline new productions, and experiment creatively, all without sacrificing the energy and emotion that make their videos stand out.

Why CrunchLabs Needed More Flexible Audio Control for International Expansion

As CrunchLabs expanded to new platforms and international audiences, the production team faced a major challenge: much of their video library was fully mixed, combining dialogue, music, and sound effects into a single track. This made it difficult to create dubbed versions for different languages or prepare rapid edits for sponsorships, social media, and regional variations. Without a way to separate these elements, workflows were slow, labor-intensive, and risked compromising the quality and energy of the original videos.

AudioShake’s ability to isolate dialogue, music, and effects from fully mixed tracks gave the team the flexibility and speed required for global distribution and promotional needs.

Creating Copyright-Compliant Versions for Worldwide Distribution

With sound separation, CrunchLabs’ production team was able to tackle the complex audio challenges that had slowed their workflows, including:

• Preparing content for global audiences: By isolating dialogue from music and effects, the team created localized versions of their videos in multiple languages while keeping the original energy and reactions intact.
• Create copyright-compliant content globally: CrunchLabs removed commercial music with expired or restricted licenses and replaced it with tracks cleared for international use, enabling confident distribution across regions without legal or licensing issues.
• Repurpose and extend the life of archived content: Older videos that were previously locked in fully mixed audio could now be re-edited, remixed, or adapted for new formats and platforms without needing to return to the original recordings.

The team also found unexpected value in the way non-verbal human sounds were preserved in the background and effects tracks. These sounds, such as laughter, exclamations, or reactions, were critical for maintaining the authenticity and emotional impact of the videos, especially when using AI-driven dubbing for international translations.

By unlocking these capabilities, CrunchLabs could move faster, release content in new formats and languages, and expand its global reach, all while maintaining the high-quality production standards its audience expects.
