AuralKit 3.0 adds transcription of selected audio tracks from local video with timestamps

rudrank · x · 2026-11-13

The open-source Swift package AuralKit 3.0 can now transcribe a chosen audio track from a local video or media file on iOS and macOS 27, with results preserving timestamps on the media timeline. stopTranscribing() is replaced by finishTranscribing() (finish capture and get final results for queued audio) and cancelTranscribing() (abandon the run; the stream ends with CancellationError). On OS 27, screen capture can feed compatible sample buffers directly into Speech, buffered audio drains on Finish, and the microphone input uses a throwing, Sendable tap. Fixes contributed by Alex Ehlke.
