.TH MIX_CreateMixerDevice 3 "SDL_mixer 3.2.0" "SDL_mixer" "SDL_mixer3 FUNCTIONS"
.SH NAME
MIX_CreateMixerDevice \- Create a mixer that plays sound directly to an audio device\[char46]
.SH SYNOPSIS
.nf
.B #include <SDL3_mixer/SDL_mixer.h>
.PP
.BI "MIX_Mixer * MIX_CreateMixerDevice(SDL_AudioDeviceID devid, const SDL_AudioSpec *spec);
.fi
.SH DESCRIPTION
This is usually the function you want, vs
.BR MIX_CreateMixer ()\[char46]
.PP
You can choose a specific device ID to open, following SDL\(aqs usual rules, but often the correct choice is to specify SDL_AUDIO_DEVICE_DEFAULT_PLAYBACK and let SDL figure out what device to use (and seamlessly transition you to new hardware if the default changes)\[char46]
.PP
Only playback devices make sense here\[char46] Attempting to open a recording device will fail\[char46]
.PP
This will call SDL_Init(SDL_INIT_AUDIO) internally; it\(aqs safe to call SDL_Init() before this call, too, if you intend to enumerate audio devices to choose one to open here\[char46]
.PP
An audio format can be requested, and the system will try to set the hardware to those specifications, or as close as possible, but this is just a hint\[char46] SDL_mixer will handle all data conversion behind the scenes in any case, and specifying a NULL spec is a reasonable choice\[char46] The best reason to specify a format is because you know all your data is in that format and it might save some unnecessary CPU time on conversion\[char46]
.PP
The actual device format chosen is available through
.BR MIX_GetMixerFormat ()\[char46]
.PP
Once a mixer is created, next steps are usually to load audio (through
.BR MIX_LoadAudio ()
and friends), create a track
.BR "" ( MIX_CreateTrack ()),
and play that audio through that track\[char46]
.PP
When done with the mixer, it can be destroyed with
.BR MIX_DestroyMixer ()\[char46]

.SH FUNCTION PARAMETERS
.TP
.I devid
the device to open for playback, or SDL_AUDIO_DEVICE_DEFAULT_PLAYBACK for the default\[char46]
.TP
.I spec
the audio format to request from the device\[char46] May be NULL\[char46]
.SH RETURN VALUE
Returns a mixer that can be used to play audio, or NULL on failure; call SDL_GetError() for more information\[char46]

.SH THREAD SAFETY
This function should only be called on the main thread\[char46]

.SH AVAILABILITY
This function is available since SDL_mixer 3\[char46]0\[char46]0\[char46]
