Overview

Not verified in this deployment: upload M4A and other supported audio through an Audelyr signed POST policy, or submit an HTTPS audio URL, then poll the asynchronous job.

02

Before you begin

Create a project API key in the console and keep it on your server.

03

Supported offline audio

Asynchronous transcription accepts AAC, AIFF, AMR, ASF, FLAC, MP3, OGG, WAV, WebM, M4A and MP4. For M4A uploads use audio/mp4, audio/x-m4a or audio/m4a. Realtime WebSocket input remains PCM16 or WebM/Opus.

04

Request lifecycle

Realtime connections return events as audio is processed. HTTP and SSE endpoints return structured errors when a request cannot run.

05

Availability

Each guide states whether its capability is available today or still planned. Do not send production traffic to an endpoint marked unavailable.
