/// Speaker mode types.
///
/// Note below the phrase 'sound channels' is used. These are the subchannels inside a sound, they are not related and have nothing to do with the FMOD class "Channel".
///
/// For example a mono sound has 1 sound channel, a stereo sound has 2 sound channels, and an AC3 or 6 channel wav file have 6 "sound channels".
///
/// [`FMOD_SPEAKERMODE_RAW`]
/// This mode is for output devices that are not specifically mono/stereo/quad/surround/5.1 or 7.1, but are multi-channel.
/// - Use [`SystemBuilder::software_format`] to specify the number of speakers you want to address, otherwise it will default to 2 (stereo).
/// - Sound channels map to speakers sequentially, so a mono sound maps to output speaker 0, stereo sound maps to output speaker 0 & 1.
/// - The user assumes knowledge of the speaker order. [`Speaker`] enumerations may not apply, so raw channel indices should be used.
/// - Multi-channel sounds map input channels to output channels 1:1.
/// - Speaker levels must be manually set with [`ChannelControl::set_mix_matrix`].
/// - [`ChannelControl::set_pan`] and [`ChannelControl::set_mix_levels_output`] do not work.
///
/// [`FMOD_SPEAKERMODE_MONO`]
/// This mode is for a 1 speaker arrangement.
///
/// - Panning does not work in this speaker mode.
/// - Mono, stereo and multi-channel sounds have each sound channel played on the one speaker at unity.
/// - Mix behavior for multi-channel sounds can be set with [`ChannelControl::set_mix_matrix`].
///
/// [`FMOD_SPEAKERMODE_STEREO`]
/// This mode is for 2 speaker arrangements that have a left and right speaker.
///
/// - Mono sounds default to an even distribution between left and right. They can be panned with [`ChannelControl::set_pan`].
/// - Stereo sounds default to the middle, or full left in the left speaker and full right in the right speaker.
///   They can be cross faded with [`ChannelControl::set_pan`].
/// - Multi-channel sounds have each sound channel played on each speaker at unity.
/// - Mix behavior for multi-channel sounds can be set with [`ChannelControl::set_mix_matrix`].
///
/// [`FMOD_SPEAKERMODE_QUAD`]
/// This mode is for 4 speaker arrangements that have a front left, front right, surround left and a surround right speaker.
///
/// - Mono sounds default to an even distribution between front left and front right. They can be panned with [`ChannelControl::set_pan`].
/// - Stereo sounds default to the left sound channel played on the front left, and the right sound channel played on the front right.
///   They can be cross faded with [`ChannelControl::set_pan`].
/// - Multi-channel sounds default to all of their sound channels being played on each speaker in order of input.
/// - Mix behavior for multi-channel sounds can be set with [`ChannelControl::set_mix_matrix`].
///
/// [`FMOD_SPEAKERMODE_SURROUND`]
/// This mode is for 5 speaker arrangements that have a left/right/center/surround left/surround right.
///
/// - Mono sounds default to the center speaker. They can be panned with [`ChannelControl::set_pan`].
/// - Stereo sounds default to the left sound channel played on the front left, and the right sound channel played on the front right.
///   They can be cross faded with [`ChannelControl::set_pan`].
/// - Multi-channel sounds default to all of their sound channels being played on each speaker in order of input.
/// - Mix behavior for multi-channel sounds can be set with [`ChannelControl::set_mix_matrix`].
///
/// [`FMOD_SPEAKERMODE_5POINT1`]
/// This mode is for 5.1 speaker arrangements that have a left/right/center/surround left/surround right and a subwoofer speaker.
///
/// - Mono sounds default to the center speaker. They can be panned with [`ChannelControl::set_pan`].
/// - Stereo sounds default to the left sound channel played on the front left, and the right sound channel played on the front right.
///   They can be cross faded with [`ChannelControl::set_pan`].
/// - Multi-channel sounds default to all of their sound channels being played on each speaker in order of input.
/// - Mix behavior for multi-channel sounds can be set with [`ChannelControl::set_mix_matrix`].
///
/// [`FMOD_SPEAKERMODE_7POINT1`]
/// This mode is for 7.1 speaker arrangements that have a left/right/center/surround left/surround right/rear left/rear right and a subwoofer speaker.
///
/// - Mono sounds default to the center speaker. They can be panned with [`ChannelControl::set_pan`].
/// - Stereo sounds default to the left sound channel played on the front left, and the right sound channel played on the front right.
///   They can be cross faded with [`ChannelControl::set_pan`].
