DeepFilterNet 降噪插件

npm i @seastart/srtc-web-sdk @seastart/srtc-plugin-deepfilternet

# 拉取资源到包的 assets/（发布到 npm 的版本已内置，此步仅作兜底）
npm run fetch-assets --prefix node_modules/@seastart/srtc-plugin-deepfilternet

# 拷贝到你的静态目录
cp -r node_modules/@seastart/srtc-plugin-deepfilternet/assets/v2 public/deepfilternet/v2

import SRTC from "@seastart/srtc-web-sdk";
import { DeepFilterNetProcessor } from "@seastart/srtc-plugin-deepfilternet";

const srtc = new SRTC();

// 1. 创建并采集麦克风
const mic = srtc.createLocalMicTrack();
await mic.startCapture({ deviceId });

// 2. 开启降噪（assetBasePath 指向上一步托管资源的目录）
const processor = new DeepFilterNetProcessor({
  assetBasePath: "/deepfilternet/",
  suppressionLevel: 50,
});
await mic.setProcessor(processor);

// 3. 发布
await srtc.publishLocalTrack(mic);

processor.setSuppressionLevel(80); // 0–100
processor.setEnabled(false);       // 旁路（输出原始音频）
processor.setEnabled(true);        // 恢复降噪

await mic.removeProcessor();
