Member Enumeration Documentation

◆ command_index

enum openmpt::module::command_index

Parameter index to use with openmpt::module::get_pattern_row_channel_command, openmpt::module::format_pattern_row_channel_command and openmpt::module::highlight_pattern_row_channel_command.

Enumerator
command_note
command_instrument
command_volumeffect
command_effect
command_volume
command_parameter

◆ render_param

enum openmpt::module::render_param

Parameter index to use with openmpt::module::get_render_param and openmpt::module::set_render_param.

Enumerator
RENDER_MASTERGAIN_MILLIBEL	Master Gain. The related value represents a relative gain in milliBel. The default value is 0. The supported value range is unlimited.
RENDER_STEREOSEPARATION_PERCENT	Stereo Separation. The related value represents the stereo separation generated by the libopenmpt mixer in percent. The default value is 100. The supported value range is [0,200].
RENDER_INTERPOLATIONFILTER_LENGTH	Interpolation Filter. The related value represents the interpolation filter length used by the libopenmpt mixer. The default value is 0, which indicates a recommended default value. The supported value range is [0,inf). Values greater than the implementation limit are clamped to the maximum supported value. Currently supported values: 0: internal default 1: no interpolation (zero order hold) 2: linear interpolation 4: cubic interpolation 8: windowed sinc with 8 taps
RENDER_VOLUMERAMPING_STRENGTH	Volume Ramping Strength. The related value represents the amount of volume ramping done by the libopenmpt mixer. The default value is -1, which indicates a recommended default value. The meaningful value range is [-1..10]. A value of 0 completely disables volume ramping. This might cause clicks in sound output. Higher values imply slower/softer volume ramps.

◆ get_ctls()

LIBOPENMPT_CXX_API_MEMBER std::vector< std::string > openmpt::module::get_ctls ( ) const

Retrieve supported ctl keys.

Returns: A vector containing all supported ctl keys.

Remarks

Currently supported ctl values are:

load.skip_samples (boolean): Set to "1" to avoid loading samples into memory
load.skip_patterns (boolean): Set to "1" to avoid loading patterns into memory
load.skip_plugins (boolean): Set to "1" to avoid loading plugins
load.skip_subsongs_init (boolean): Set to "1" to avoid pre-initializing sub-songs. Skipping results in faster module loading but slower seeking.
seek.sync_samples (boolean): Set to "0" to not sync sample playback when using openmpt::module::set_position_seconds or openmpt::module::set_position_order_row.
subsong (integer): The current subsong. Setting it has identical semantics as openmpt::module::select_subsong(), getting it returns the currently selected subsong.
play.at_end (text): Chooses the behaviour when the end of song is reached. The song end is considered to be reached after the number of reptitions set by openmpt::module::set_repeat_count was played, so if the song is set to repeat infinitely, its end is never considered to be reached.
- "fadeout": Fades the module out for a short while. Subsequent reads after the fadeout will return 0 rendered frames.
- "continue": Returns 0 rendered frames when the song end is reached. Subsequent reads will continue playing from the loop start (if the song is not programmed to loop, playback resumsed from the song start).
- "stop": Returns 0 rendered frames when the song end is reached. Subsequent reads will return 0 rendered frames.
play.tempo_factor (floatingpoint): Set a floating point tempo factor. "1.0" is the default tempo.
play.pitch_factor (floatingpoint): Set a floating point pitch factor. "1.0" is the default pitch.
render.resampler.emulate_amiga (boolean): Set to "1" to enable the Amiga resampler for Amiga modules. This emulates the sound characteristics of the Paula chip and overrides the selected interpolation filter. Non-Amiga module formats are not affected by this setting.
render.resampler.emulate_amiga_type (string): Configures the filter type to use for the Amiga resampler. Supported values are:
- "auto": Filter type is chosen by the library and might change. This is the default.
- "a500": Amiga A500 filter.
- "a1200": Amiga A1200 filter.
- "unfiltered": BLEP synthesis without model-specific filters. The LED filter is ignored by this setting. This filter mode is considered to be experimental and might change in the future.
render.opl.volume_factor (floatingpoint): Set volume factor applied to synthesized OPL sounds, relative to the default OPL volume.
dither (integer): Set the dither algorithm that is used for the 16 bit versions of openmpt::module::read. Supported values are:
- 0: No dithering.
- 1: Default mode. Chosen by OpenMPT code, might change.
- 2: Rectangular, 0.5 bit depth, no noise shaping (original ModPlug Tracker).
- 3: Rectangular, 1 bit depth, simple 1st order noise shaping

An exclamation mark ("!") or a question mark ("?") can be appended to any ctl key in order to influence the behaviour in case of an unknown ctl key. "!" causes an exception to be thrown; "?" causes the ctl to be silently ignored. In case neither is appended to the key name, unknown init_ctls are ignored by default and other ctls throw an exception by default.

LIBOPENMPT_CXX_API_MEMBER std::size_t openmpt::module::read_interleaved_quad	(	std::int32_t	samplerate,
		std::size_t	count,
		float *	interleaved_quad
	)

Render audio data.

Parameters

samplerate	Sample rate to render output. Should be in [8000,192000], but this is not enforced.
count	Number of audio frames to render per channel.
interleaved_quad	Pointer to a buffer of at least count*4 elements that receives the interleaved quad surround output in the order (L,R,RL,RR).

Returns: The number of frames actually rendered.

Return values

0	The end of song has been reached.

Remarks: The output buffers are only written to up to the returned number of elements.; You can freely switch between any of the "read*" variants if you see a need to do so. libopenmpt tries to introduce as little switching annoyances as possible. Normally, you would only use a single one of these functions for rendering a particular module.; Floating point samples are in the [-1.0..1.0] nominal range. They are not clipped to that range though and thus might overshoot.

◆ read_interleaved_quad() [2/2]

LIBOPENMPT_CXX_API_MEMBER std::size_t openmpt::module::read_interleaved_quad	(	std::int32_t	samplerate,
		std::size_t	count,
		std::int16_t *	interleaved_quad
	)

Render audio data.

Parameters

samplerate	Sample rate to render output. Should be in [8000,192000], but this is not enforced.
count	Number of audio frames to render per channel.
interleaved_quad	Pointer to a buffer of at least count*4 elements that receives the interleaved quad surround output in the order (L,R,RL,RR).

Returns: The number of frames actually rendered.

Return values

◆ select_subsong()

LIBOPENMPT_CXX_API_MEMBER void openmpt::module::select_subsong ( std::int32_t subsong )

Select a sub-song from a multi-song module.

Parameters

subsong Index of the sub-song. -1 plays all sub-songs consecutively.

Exceptions

openmpt::exception Throws an exception derived from openmpt::exception if sub-song is not in range [-1,openmpt::module::get_num_subsongs()[

See also: openmpt::module::get_num_subsongs, openmpt::module::get_selected_subsong, openmpt::module::get_subsong_names

Remarks: Whether subsong -1 (all subsongs consecutively), subsong 0 or some other subsong is selected by default, is an implementation detail and subject to change. If you do not want to care about subsongs, it is recommended to just not call openmpt::module::select_subsong() at all.

◆ set_position_order_row()

LIBOPENMPT_CXX_API_MEMBER double openmpt::module::set_position_order_row	(	std::int32_t	order,
		std::int32_t	row
	)

Set approximate current song position.

If order or row are out of range, to position is not modified and the current position is returned.

Parameters

order	Pattern order number to seek to.
row	Pattern row number to seek to.

Returns: Approximate new song position in seconds.

See also: openmpt::module::set_position_seconds; openmpt::module::get_position_seconds

◆ set_position_seconds()

LIBOPENMPT_CXX_API_MEMBER double openmpt::module::set_position_seconds ( double seconds )

Set approximate current song position.

Parameters

seconds Seconds to seek to. If seconds is out of range, the position gets set to song start or end respectively.

Returns: Approximate new song position in seconds.

See also: openmpt::module::get_position_seconds

◆ set_render_param()

LIBOPENMPT_CXX_API_MEMBER void openmpt::module::set_render_param	(	int	param,
		std::int32_t	value
	)

Set render parameter.

Parameters

param	Parameter to set. See openmpt::module::render_param.
value	The value to set param to.

Exceptions

openmpt::exception Throws an exception derived from openmpt::exception if param is invalid or value is out of range.

See also: openmpt::module::render_param; openmpt::module::get_render_param

◆ set_repeat_count()

LIBOPENMPT_CXX_API_MEMBER void openmpt::module::set_repeat_count ( std::int32_t repeat_count )

Set Repeat Count.

Parameters

repeat_count

Repeat Count

-1: repeat forever
0: play once, repeat zero times (the default)
n>0: play once and repeat n times after that
