Gather Town Rebuilds Audio Pipeline From Scratch to Fix Reliability Issues in 2.0.

Gather Town shipped its biggest redesign in years when it launched version 2.0, but the audio and video quality wasn't good enough. The team has now rebuilt the entire AV pipeline from the ground up, switching from JavaScript to C++ and untangling a Windows 11 bug that was quietly degrading call quality in the background.

The company announced on LinkedIn that the overhaul has reduced low AV quality ratings by 50% since the initial 2.0 launch. The platform, which lets remote teams hold multiple simultaneous conversations in a spatial video environment, had been struggling with reliability issues that affected the core product experience.

The rebuild involved replacing the JavaScript-based audio processing layer with C++, a lower-level language that offers more direct control over system resources and better performance for real-time media. According to the company's blog post, this rewrite addressed fundamental architectural problems that couldn't be patched incrementally.

The team also discovered that a Windows 11 update was throttling background processes in ways that interfered with audio transmission during calls. Isolating and working around this OS-level behavior required deep debugging across multiple system layers. The combination of the C++ migration and the Windows fix appears to have resolved the most common failure modes users were reporting.

Gather Town thanked users who submitted bug reports and remained on the platform during what the company described as "rough patches." The acknowledgment suggests the audio problems were severe enough to risk user churn, a critical concern for a product where call quality is table stakes.

Reliable audio is non-negotiable for tools competing in the virtual workspace category. Slack, Discord, and Zoom have all spent years optimizing their media stacks, and any new platform needs to match that baseline or risk losing users to established alternatives.

Gather's spatial audio model, where conversations fade in and out as avatars move closer or farther apart, adds complexity that standard grid-based video platforms don't face. The technical challenge is higher, and so is the penalty for failure. Users expect seamless transitions between conversations, not dropped audio or crackling connections.

The 50% reduction in low ratings is a meaningful improvement, but it also implies that quality issues persist for a meaningful subset of users. The company indicated it's continuing to iterate, which suggests this rebuild is a foundation rather than a final fix.

Gather has been adding features like animated avatar reactions and go-kart mode for faster navigation in recent months, but none of those enhancements matter if the underlying AV infrastructure is unreliable. This technical debt appears to have been a top priority for the engineering team.

The full technical write-up is available on the Gather blog, where the team promises more detail on what broke, how they fixed it, and what's planned next for the platform's infrastructure.
