API Overview

startRecording

Start recording audio using the device microphone.

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

await CapacitorAudioRecorder.startRecording();

pauseRecording

Pause the ongoing recording. Only available on Android (API 24+), iOS, and Web.

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

await CapacitorAudioRecorder.pauseRecording();

resumeRecording

Resume a previously paused recording.

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

await CapacitorAudioRecorder.resumeRecording();

stopRecording

Stop the current recording and persist the recorded audio.

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

await CapacitorAudioRecorder.stopRecording();

cancelRecording

Cancel the current recording and discard any captured audio.

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

await CapacitorAudioRecorder.cancelRecording();

getRecordingStatus

Retrieve the current recording status.

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

await CapacitorAudioRecorder.getRecordingStatus();

getCurrentAmplitude

Retrieve the current input amplitude (microphone level) as a normalized number in the [0, 1] range.

Intended for driving live visualizations such as VU meters or waveforms while recording. Returns 0 when no recording is active. Designed for UI-rate polling — a 60–100 ms interval is a good starting point for a waveform. Avoid calling it in a tight loop; each call crosses the JS/native bridge.

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

await CapacitorAudioRecorder.getCurrentAmplitude();

checkPermissions

Return the current permission state for accessing the microphone.

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

await CapacitorAudioRecorder.checkPermissions();

requestPermissions

Request permission to access the microphone.

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

await CapacitorAudioRecorder.requestPermissions();

GetCurrentAmplitudeResult

Result returned by .

export interface GetCurrentAmplitudeResult {

   * Note: the source signal differs between platforms — Android reports the
   * peak sample amplitude since the last call, iOS reports the average power
   * in dB converted to linear, and Web reports the RMS of the latest frame.
   * Consumers that need cross-platform parity may want to apply a
   * per-platform scaling curve.
