279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	37 * ALmixer exposes OpenAL sources in the API so you can freely use ALmixer

279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	41 * The API is heavily influenced and inspired by SDL_mixer, though there is one major
279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	42 * conceptual design difference. ALmixer doesn't divide sound and music playback into two
279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	43 * separate play APIs. Instead, there is one unified play API and you specify via the

279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	45 * This allows you to have any arbitrary number of streaming sources playing simultaneously

279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	49 * A less major conceptual design difference is every "Channel" API has a corresponding "Source" API.
279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	50 * Every "channel" (in the SDL_mixer definition context) maps to a corresponding OpenAL source id. You can use
279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	51 * this source ID directly with OpenAL API commands to utilize OpenAL effects such as position, Doppler, etc.

279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	55 * ALmixer callbacks allow you to pass user_data (aka context) pointers through the callback functions.

279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	62 * be blocked for long periods and thus less likely your buffer queues will be starved. However, this means you
279d0427ef26 Overhaul prep for first public release. Eric Wing <ewing . public \|-at-\| gmail . com> parents: 1 diff changeset	63 * need to be extra careful about what you do in callback functions as they are invoked from the background thread.
