Playing Audio Data Generated on the Audio Engine Server

Application Scenario

Play the audio data sent from the audio engine server by calling the API provided by the audio engine.

Prerequisites

N/A

Development Process

1. Receive the audio data sent from the audio engine server through the communication module.
2. Call the API provided by the audio engine client to play the audio.
3. Register the hook function for saving the audio data on the client. The audio engine client saves the received audio data by using the hook function.
4. Call the API provided by the audio engine client to enable or disable audio playback.

Encoding Instance

Scenario

According to the development process, call the API of the audio engine client to play the audio data sent by the server and save the audio data.
