Good evening, and welcome to Frigate NVR Updates for August 16, 2026.
Today's activity centers on two distinct but practical improvements: smarter audio classification and leaner internal resource use.
First, audio detection. PR 24004, from contributor Ersaoktaviannn, introduces an audio label map option. This lets users group multiple audio classes under a single label. Instead of separately managing similar sounds, you'll be able to bucket them together in your configuration. This closes out two open issues,…
Second, efficiency under the hood. PR 24002, from hawkeye217, has already been merged after one approval. It stops the system from creating a separate configuration subscriber for every capture thread. If you're running Frigate with multiple cameras, each with its own capture thread, this previously meant duplicated…
Taken together, these two changes reflect ongoing refinement rather than a single dramatic overhaul: one improves flexibility for users configuring audio detection, the other trims internal inefficiency in how the system manages state across threads. Neither is a breaking change, but both are the kind of incremental…
What's next: watch for the audio labelmap…
