✨ pysilk-cffi ✨

The cffi binding for silk-v3-decoder

安装

pip install pysilk-cffi

使用

• encode

import pysilk

with open("verybiginput.pcm", "rb") as pcm, open("output.silk", "wb") as silk:
    pysilk.encode(pcm, silk, 24000, 24000)

• decode

import pysilk

with open("verybiginput.silk", "rb") as silk, open("output.pcm", "wb") as pcm:
    pysilk.decode(silk, pcm, 24000)

支持功能

• 接受任何二进制的file-like object，比如BytesIO，可以流式解码大文件
• 包装了silk的全部C接口的参数，当然他们都有合理的默认值
