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.
The full audio recording process includes creating an instance, setting recording parameters, starting, pausing, resuming, and stopping recording, and releasing resources.
