{{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. Playing with other sounds is possible if the Z80 coprocessor is handling the playback, however the DAC uses a few of the channels and therefore some of them will not be heard if DAC streaming begins during regular FM audio playback.

'''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.

Go doesn't have any audio support in its standard library and it's best therefore to invoke a utility such as SoX to complete a task such as this.
Although there is at least one third party library which provides Go bindings to the libsox sound library, for casual use it's far easier to invoke SoX directly with a list of arguments.
See the PicoLisp entry for a description of what these particular arguments do.

Gtk GUI app version using SoX play. All task suggestions except stereo and position mixing are supported.
Supported formats are MP2, WAV, OGG, FLAC, , AIFF, and many others through the libsndfile library.
This makes a good music player. There is a slight latency to load the player, so very low game
latencies would not be well supported.

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.

The above library currently supports playback of OGG and WAV files, with a sample frequency of 44.1kHz.
It is certainly suitable for game sound effects (it's a game engine) and can play music at CD quality as well.

{{works with|Sega Genesis}}
This routine streams an unsigned 8-bit PCM sample to the [[wp:Yamaha_YM2612|Yamaha 2612's]] [[wp:Digital-to-analog_converter|DAC]] in order to play a recorded sound. Unfortunately, the Sega Genesis's Z80 coprocessor can only access a limited pool of memory, so any PCM samples will have to be copied from the cartridge ROM to the shared memory area.
