The full audio playback process includes creating an instance, setting the URI, playing audio, seeking to the playback position, setting the volume, pausing playback, obtaining track information, stopping playback, resetting resources, and releasing resources.
For details about the **src** media source input types supported by **AudioPlayer**, see the [src attribute](../reference/apis/js-apis-media.md#audioplayer_attributes).
During audio recording, audio signals are captured, encoded, and saved to files. You can specify parameters such as the sampling rate, number of audio channels, encoding format, encapsulation format, and file path for audio recording.
For details about the APIs used for audio recording, see [js-apis-media.md](../reference/apis/js-apis-media.md).

包含流程：创建实例，设置录制参数，录制音频，暂停录制，恢复录制，停止录制，释放资源等流程。
The full audio recording process includes creating an instance, setting recording parameters, starting, pausing, resuming, and stopping recording, and releasing resources.
// To use the media library, declare the following permissions: ohos.permission.MEDIA_LOCATION, ohos.permission.WRITE_MEDIA, and ohos.permission.READ_MEDIA.
audioRecorder.stop();// The stop method can be called to trigger the 'stop' event callback only after the 'start' or 'resume' event callback is complete.
// To use the media library, declare the following permissions: ohos.permission.MEDIA_LOCATION, ohos.permission.WRITE_MEDIA, and ohos.permission.READ_MEDIA.
audioRecorder.stop();// The stop method can be called to trigger the 'stop' event callback only after the 'start' or 'resume' event callback is complete.
// 6.释放资源
// 6. Release resources.
audioRecorder.release();// audioRecorder资源被销毁
audioRecorder.release();// The AudioRecorder resource is destroyed.
During video recording, audio and video signals are captured, encoded, and saved to files. You can specify parameters such as the encoding format, encapsulation format, and file path for video recording.
For details about the APIs used for video recording, see [js-apis-media.md](../reference/apis/js-apis-media.md).
