Upgrading?

AI Summary

Fixed a critical memory leak in STT send loops that retained audio frames indefinitely, consuming significant memory (approx. 8MB/min per stream).

Key Highlights

  • Fixed memory leak in STT send loops
  • Reads now use cancellable signals to prevent frame retention
  • Queue.get and AsyncIterableQueue.next now honor aborted signals

Full Release Notes

### Patch Changes

-   Stop the STT send loops from retaining every audio frame for the life of a stream, and from stealing the next attempt's first frame. `inference.STT` and the Cartesia, Deepgram and Meta STTs raced each read against one long-lived abort promise; every race appended a reaction to that never-settling promise, and each reaction kept the settled read and its `AudioFrame` alive (nodejs/node#17469) — about 8 MB per minute per stream under continuous speech, until the job hit its memory limit. Reads now go through the input queue's cancellable `next({ signal })`, so a torn-down sender's read is cancelled instead of left parked in the queue, and any remaining race goes through `waitUntilAborted`, which installs and removes its own abort listener per call. `Queue.get` and `AsyncIterableQueue.next` now honour an already-aborted signal even when items are buffered, so a cancelled reader never takes a frame the replacement reader needs. - [#2544](https://github.com/livekit/agents-js/pull/2544) ([@praveen4star](https://github.com/praveen4star))
