# AssemblyAI Core Workflow A — Async Transcription ## Overview Primary money-path workflow: submit audio for async transcription with audio intelligence features. The SDK handles file upload (for local files), queues the transcription job, and polls until completion. ## Prerequisites - `assemblyai` package installed - API key configured in `ASSEMBLYAI_API_KEY` ## Instructions ### Step 1: Basic Async Transcription ```typescript import { AssemblyAI } from 'assemblyai'; const client = new AssemblyAI({ apiKey: process.env.ASSEMBLYAI_API_KEY!, }); // Remote URL — SDK queues and polls automatically const transcript = await client.transcripts.transcribe({ audio: 'https://example.com/meeting-recording.mp3', }); console.log(transcript.text); console.log(`Duration: ${transcript.audio_duration}s`); console.log(`Words: ${transcript.words?.length}`); ``` ### Step 2: Local File Upload ```typescript // The SDK uploads the file and transcribes in one call const transcript = await client.transcripts.transcribe({ audio: './recordings/interview.wav', }); // Or from a buffer/stream import fs from 'fs'; const buffer = fs.readFileSync('./recordings/interview.wav'); const transcript2 = await client.transcripts.transcribe({ audio: buffer, }); ``` ### Step 3: Speaker Diarization ```typescript const transcript = await client.transcripts.transcribe({ audio: audioUrl, speaker_labels: true, speakers_expected: 3, // Optional: hint for expected speaker count }); // Utterances a...
