Set the number of channels to be mixed. Opening too many channels may result in a segfault. This can be called at any time even while samples are playing. Passing a number lower than previous calls will close unused channels. It returns the number of channels allocated. NOTE: Channels are 0 indexed!
Closes the mixer
Free the memory used in the chunk and then free the chunk itself. Do not free the chunk while it is playing; halt the channel it’s playing on using halt-channel prior to freeing the chunk.
Halt the channel or pass -1 to halt all channels. Always returns 0. NOTE: Channels are 0 indexed!
Halts the playback of all music
Initialize the SDL mixer specifying the formats you wish to use. Must be one of these values or a combination thereof :ogg, :wave, :mod, :mp3
Returns the version number for SDL Mixer 2
Loads music from a file. Returns a mix-music object
Loads the sample specified by the sample-file-name. Returns a mix-chunk. sdl2-mixer must be initialized and open-audio must be called prior to.
Initialize the mixer specifiying the output sample format, number of output
channels (1 mono or 2 for stereo), and bytes used per output sample. format must
be one of the following values, :u8, :s8, :u16lsb, :s16lsb, :u16msb, :s16msb,
:u16, :s16, :u16sys, :s16sys, :s32lsb, :s32msb, :s32sys, :s32, :f32lsb, :f32msb, :f32sys, :f32
Plays the mix-chunk (sound effect) loops+1 times on a given channel. Passing -1 for the channel will play it on the first unreserved channel. Returns the channel the sample is played on. NOTE: Channels are 0 indexed!
Play the music as many times as specified by the optional loops argument. By default loops is -1 which makes the music loop indefinitely. Returns 0 on success -1 on error
Checks whether or not a channel is currently playing. It will return a 1 for playing and 0 otherwise. Passing -1 for the channel will specify how many channels are playing.
Gets the output format in use by the opened audio device
Cleans up SDL Mixer
Set the volume on a given channel, pass -1 to set the volume for all channels. The volume may range from 0 to 128. Passing in a number higher than the maximum will automatically set it to the maximum while passing in a negatiev will automatically set it to 0. Returns the current volume of the channel. NOTE: Channels are 0 indexed!
Adjust the volume of the music. Volume ranges from 0 to 128. The return value is an integer that usually represents the previous volume setting. Passing -1 as the music volume does not change the volume but instead returns the current volume setting
