-[AudioRenderer](using-audiorenderer-for-playback.md): provides ArkTS and JS API to implement audio output. It supports only the PCM format and requires applications to continuously write audio data. The applications can perform data preprocessing, for example, setting the sampling rate and bit width of audio files, before audio input. This class can be used to develop more professional and diverse playback applications. To use this class, you must have basic audio processing knowledge.
-[OpenSL ES](using-opensl-es-for-playback.md): provides a set of standard, cross-platform, yet unique native audio APIs. It supports audio output in PCM format and is applicable to playback applications that are ported from other embedded platforms or that implements audio output at the native layer.

-[TonePlayer](using-toneplayer-for-playback.md): provides ArkTS and JS API to implement the playback of dialing tones and ringback tones. It can be used to play the content selected from a fixed type range, without requiring the input of media assets or audio data. This class is application to specific scenarios where dialing tones and ringback tones are played. is available only to system applications.
-[Using OHAudio for Audio Playback](using-ohaudio-for-playback.md): provides a set of native APIs for audio output. These APIs are normalized in design and support both common and low-latency audio channels. They are suitable for playback applications that implement audio output at the native layer.

- Applications often need to use short sound effects, such as camera shutter sound effect, key press sound effect, and game shooting sound effect. Currently, only the **AVPlayer** class can implement audio file playback. More APIs will be provided to support this scenario in later versions.
