Deepgram Core Workflow A: Pre-recorded Transcription

Overview

Production pre-recorded transcription service using Deepgram's REST API. Covers transcribeUrl and transcribeFile, speaker diarization, audio intelligence (summarization, topic detection, sentiment, intent), batch processing with concurrency control, and callback-based async transcription for large files.

Prerequisites

• @deepgram/sdk installed, DEEPGRAM_API_KEY configured
• Audio files: WAV, MP3, FLAC, OGG, M4A, or WebM
• For batch: p-limit package (npm install p-limit)
