## What it is
A C-based Silk v3 audio decoder (from the Skype Silk Codec SDK) wrapped in shell scripts that decodes WeChat amr/aud, QQ slk, and other Silk v3 audio files and converts them to formats like MP3 via ffmpeg. It supports single-file and batch folder conversion, plus Silk v3 encoding compatible with WeChat/QQ.

## Use cases
- convert wechat voice messages to mp3
- decode qq slk audio files
- batch convert silk v3 audio folder
