Implements real-time mono audio capture and transcoding via Web Audio API, supporting arbitrary MediaStream sources (microphone, WebRTC remote streams, media element captures) with pluggable encoders for multiple formats and optional real-time processing pipelines. Core architecture uses frame-based PCM buffering with streaming transcoding support, enabling low-latency scenarios like live ASR integration and concurrent multi-stream audio mixing. Targets browser environments (Chrome, Firefox, Safari, WeChat/QQ WebView) and non-browser contexts (Node.js, mini-programs via RecordApp wrapper) with modular encoder plugins and DSP utilities (FFT, IIR filters, sample rate conversion).
