# Stream session audio as WAV

- **Method:** `GET`
- **Path:** `/api/v1/streaming/{session_id}/audio`
- **Operation ID:** `stream_audio_api_v1_streaming__session_id__audio_get`
- **Tags:** Streaming

Stream generated audio progressively while synthesis runs.

Both formats are replayable and resumable: reads never consume the
session buffer, and `Range: bytes=N-` requests resume from byte N
(206), so players like ExoPlayer can recover from network drops.
MP3 is encoded once per session into a buffer all readers share.
The stream ends when generation completes. 10-minute hard timeout.
