Supported methods

Overview

The capacitor-voice-recorder plugin allows you to record audio on Android, iOS, and Web platforms. Below is a summary of the key methods and how to use them.

Checking Device Capabilities and Permissions

canDeviceVoiceRecord

Check if the device/browser can record audio.

VoiceRecorder.canDeviceVoiceRecord().then((result: GenericResponse) => console.log(result.value));

requestAudioRecordingPermission

Request audio recording permission from the user.

VoiceRecorder.requestAudioRecordingPermission().then((result: GenericResponse) => console.log(result.value));

hasAudioRecordingPermission

Check if the audio recording permission has been granted.

VoiceRecorder.hasAudioRecordingPermission().then((result: GenericResponse) => console.log(result.value));

Managing Recording

startRecording

Start the audio recording.

VoiceRecorder.startRecording()
    .then((result: GenericResponse) => console.log(result.value))
    .catch(error => console.log(error));

stopRecording

Stops the audio recording and returns the recording data.

VoiceRecorder.stopRecording()
    .then((result: RecordingData) => console.log(result.value))
    .catch(error => console.log(error));

pauseRecording

Pause the ongoing audio recording.

VoiceRecorder.pauseRecording()
    .then((result: GenericResponse) => console.log(result.value))
    .catch(error => console.log(error));

resumeRecording

Resumes a paused audio recording.

VoiceRecorder.resumeRecording()
    .then((result: GenericResponse) => console.log(result.value))
    .catch(error => console.log(error));

getCurrentStatus

Retrieves the current status of the recorder.

VoiceRecorder.getCurrentStatus()
    .then((result: CurrentRecordingStatus) => console.log(result.status))
    .catch(error => console.log(error));

Format and Mime type

The plugin will return the recording in one of several possible formats. The format is dependent on the os / web browser that the user uses. On android and ios the mime type will be audio/aac, while on chrome and firefox it will be audio/webm;codecs=opus and on safari it will be audio/mp4. Note that these three browsers have been tested on. The plugin should still work on other browsers, as there is a list of mime types that the plugin checks against the user's browser.

Note that this fact might cause unexpected behavior in case you'll try to play recordings between several devices or browsers—as they do not all support the same set of audio formats. It is recommended to convert the recordings to a format that all your target devices support. As this plugin focuses on the recording aspect, it does not provide any conversion between formats.

Playback

To play the recorded file, you can use plain JavaScript:

const base64Sound = '...' // from plugin
const mimeType = '...'  // from plugin
const audioRef = new Audio(`data:${mimeType};base64,${base64Sound}`)
audioRef.oncanplaythrough = () => audioRef.play()
audioRef.load()

Compatibility

Versioning follows Capacitor versioning. Major versions of the plugin are compatible with major versions of Capacitor. You can find each version in its own dedicated branch.
