快速入门

安装

你可以使用我们的 AI 辅助设置来安装插件。使用以下命令将 Capgo skills 添加到你的 AI 工具中：

npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

然后使用以下 prompt：

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-audio-recorder` plugin in my project.

如果你更想手动设置，请运行以下命令安装插件，并按照下方各平台的说明操作：

bun add @capgo/capacitor-audio-recorder
bunx cap sync

导入

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

快速入门

请求麦克风权限，录音，然后停止并读取原生文件 URI（或 Web Blob).

import { Capacitor } from '@capacitor/core';
import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

const mic = await CapacitorAudioRecorder.requestPermissions();
if (mic.recordAudio !== 'granted') {
  throw new Error('Microphone permission required');
}

await CapacitorAudioRecorder.startRecording({
  sampleRate: 44100,
  bitRate: 128000,
  resetToPlaybackOnStop: true, // iOS only: restore playback-friendly audio session after stop
});

const { uri, blob, duration } = await CapacitorAudioRecorder.stopRecording();
const clipRef = Capacitor.getPlatform() === 'web' ? blob : uri;
console.log('Saved clip', clipRef, duration);

示例：带暂停功能的语音备忘录

await CapacitorAudioRecorder.startRecording();
// user taps pause during a long note
await CapacitorAudioRecorder.pauseRecording();
await CapacitorAudioRecorder.resumeRecording();
const clip = await CapacitorAudioRecorder.stopRecording();

pauseRecording 适用于 Android (API 24+)、iOS 和 Web。

示例：实时电平表

轮询 getCurrentAmplitude() 通过定时器（约 60 到 100 ms）进行，当状态为 RECORDING。数值已归一化 0 改为 1, 但底层信号因平台而异（Android 为峰值，iOS 为平均功率，Web 为 RMS）。如果需要视觉一致，请按平台做小幅缩放。

const tick = async () => {
  const { status } = await CapacitorAudioRecorder.getRecordingStatus();
  if (status !== 'RECORDING') return;
  const { value } = await CapacitorAudioRecorder.getCurrentAmplitude();
  updateMeterUi(value);
};

示例：丢弃一条录音

await CapacitorAudioRecorder.startRecording();
await CapacitorAudioRecorder.cancelRecording(); // no file persisted

常见坑点

• Web 与原生返回结构：Android 和 iOS 返回 uri 来自 stopRecording。Web 返回 blob （并且可以省略 uri).
• iOS 上录音后的静音播放：设置 resetToPlaybackOnStop: true 中的 startRecording 如果用户在同一会话中回放该片段。
• 后台录音: 该插件本身不会启用后台音频。在 iOS 上，如果需要在锁屏时进行录音，请添加 Audio background mode。
• 避免频繁调用 amplitude: 每次 getCurrentAmplitude : 调用都会经过 bridge。请使用 UI interval，不要用 tight loop。

API 概览

startRecording

使用设备麦克风开始录音。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

await CapacitorAudioRecorder.startRecording();

pauseRecording

暂停正在进行的录音。仅支持 Android (API 24+)、iOS 和 Web。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

await CapacitorAudioRecorder.pauseRecording();

resumeRecording

恢复之前暂停的录音。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

await CapacitorAudioRecorder.resumeRecording();

stopRecording

停止当前录音并保存录制的音频。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

const result = await CapacitorAudioRecorder.stopRecording();
console.log(result);

cancelRecording

取消当前录音并丢弃已捕获的音频。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

await CapacitorAudioRecorder.cancelRecording();

getRecordingStatus

获取当前录音状态。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

const result = await CapacitorAudioRecorder.getRecordingStatus();
console.log(result);

getCurrentAmplitude

获取当前输入振幅（麦克风电平），返回归一化 数值，范围在 [0, 1] 指定区间内。

用于在录音时驱动 VU 表或波形图等实时可视化。返回 0 无录音时的值。专为按 UI 刷新率轮询而设计——对波形图来说，60–100 ms 的间隔是个不错的起点。避免在紧凑循环中调用；每次调用都会跨越 JS/native bridge。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

const result = await CapacitorAudioRecorder.getCurrentAmplitude();
console.log(result);

checkPermissions

返回麦克风访问权限的当前状态。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

const result = await CapacitorAudioRecorder.checkPermissions();
console.log(result);

requestPermissions

请求访问麦克风的权限。

import { CapacitorAudioRecorder } from '@capgo/capacitor-audio-recorder';

const result = await CapacitorAudioRecorder.requestPermissions();
console.log(result);
