{{works with|Sega Genesis}}
This snippet of code will stream an unsigned 8-bit PCM sample to the [[wp:Yamaha_YM2612|Yamaha 2612's]] [[wp:Digital-to-analog_converter|DAC]]. Unfortunately, the data needs to be continuously streamed, meaning that the game essentially comes to a halt while this is happening. However, a clever game designer can hide this fact quite easily by only using voice samples at key moments where the player expects a brief pause in the action.

'''Library: AVFoundation'''
FB has several native ways to play recorded sounds, ranging from simple to commercial. It also can play a variety of audio formats including mp3, m4a, aiff, wav, etc. This task code uses the AVFoundation library to create a basic player with simple controls including a popup menu from which bundled audio files can be selected.

Pygame is a library for cross-platform game development and depends on the SDL multimedia library (SDL_mixer) for its audio playback.

R's sound package uses system commands to call a built-in media player. On Windows, by default, this is Media Player. You can see the system call with <code>WavPlayer()</code>. Only .WAV files are supported, and the external code call means there is some latency before sounds are played. Samples longer than 10 minutes may correspond to significant chunks of your machine's memory.
