## What this tool does
Convert audio to the WhatsApp voice-note spec — Opus 24 kbps mono in OGG, plays like a native 语音条.

## Typical user problems
- WhatsApp plays uploaded MP3s through a generic music player, but a real voice note streams in-chat with the waveform bubble and background playback. Matching the native spec — Ogg Opus, 24 kbps VBR, mono, voip tuning — gets your clip the same lightweight treatment.
