This guide documents the recommended audio parameters for capturing voice input destined for OpenAI's Whisper API or local Whisper models. The goal is to minimize file size while preserving transcription accuracy.
| Parameter | Recommended | Notes |
|---|---|---|
| Channels | Mono (1) | Whisper converts to mono internally anyway |
| Sample Rate | 16 kHz | Native processing rate; higher is downsampled |
