Why ffvoice? / 为什么用 ffvoice？

The honest pitch: ffvoice is an integration layer, not a new ASR engine. It embeds whisper.cpp as-is and makes no changes to its accuracy or inference speed. What ffvoice adds is a batteries-included, pre-wired pipeline — microphone capture → RNNoise denoising → VAD segmentation → Whisper ASR → speaker diarization → live captions / WAV / FLAC / subtitles — delivered as a single C++ SDK with Python bindings, a CLI, and an MCP server that lets AI agents (Claude and others) transcribe audio out of the box — all in one pip install or cmake build.

诚实定位: ffvoice 是一个集成层，而非新的 ASR 引擎。它内嵌 whisper.cpp，不修改其识别精度或推理速度。ffvoice 带来的是一条开箱即用、预连接的完整管道——麦克风采集 → RNNoise 降噪 → VAD 分段 → Whisper ASR → 说话人分离 → 实时字幕 / WAV / FLAC / 字幕输出——打包成 C++ SDK + Python 绑定 + CLI，外加一个 MCP server,让 AI agent(Claude 等)开箱即用地转写音频——一条 pip install 或 cmake 即可完成。
