criAtomEx3dSource_SetMinMaxDistance

#define criAtomEx3dSource_SetMinMaxDistance	(		ex_3d_source,
			min_attenuation_distance,
			max_attenuation_distance
	)		criAtomEx3dSource_SetMinMaxAttenuationDistance((ex_3d_source), (min_attenuation_distance), (max_attenuation_distance))

Set min and max values of the attenuation distance of a 3D source

参数

[in]	ex_3d_source	3D sound source handle
[in]	min_attenuation_distance	minimum attenuation distance
[in]	max_attenuation_distance	maximum attenuation distance

Description:

Sets the minimum and maximum attenuation distances for a 3D sound source.
The minimum distance represents the distance below which the volume is maximum. The maximum distance represents the distance at which the minimum volume is reached.
The default values at the initialization of the library are as follows:

• Minimum distance: 0.0f
• Maximum distance: 0.0f

The default values can be changed by calling the criAtomEx3dSource_ChangeDefaultMinMaxDistance function.
If the minimum and maximum distances are set on the data side (i.e. in the tool), they are overwritten (ignored) when this function is called.

注意

To actually apply the specified values, you have to call the criAtomEx3dSource_Update function.

参见

criAtomEx3dSource_Update, criAtomEx3dSource_ChangeDefaultMinMaxAttenuationDistance]

criAtomEx3dSource_ChangeDefaultMinMaxDistance

#define criAtomEx3dSource_ChangeDefaultMinMaxDistance	(		min_attenuation_distance,
			max_attenuation_distance
	)		criAtomEx3dSource_ChangeDefaultMinMaxAttenuationDistance((min_attenuation_distance), (max_attenuation_distance))

Change the default values of max and min of attenuation distance of a 3D source

参数

[in]	min_attenuation_distance	minimum attenuation distance
[in]	max_attenuation_distance	maximum attenuation distance

Description:

Changes the default values for the minimum and maximum attenuation distances of a 3D sound source.
After calling this function, the new default values for minimum and maximum distance attenuation are applied each time a new 3D sound source is created.

注意

If the relevant parameters were not set in the tool, the default values are used implicitly.
Therefore, if you change the default values, the parameters may be different from the ones intended.
Note that in the following cases, parmeters will not be affected by this function:

• Min/max attenuation distance is set to something else than 0 by default in the tool's properties.
• The data is built for in-game preview.

返回

CriSint32 work buffer size

返回值

>=	0 successfully completed
-1	error occurred

Description:

Calculates the size of the work buffer required to create a 3D sound source.
If you create a 3D sound source without having registered a user-allocator, a memory buffer having the size returned by this function must be passed to criAtomEx3dSource_Create .

The size of the work buffer needed to create a 3D sound source depends on the value of the parameters in the configuration structure ( CriAtomEx3dSourceConfig ).

When NULL is specified for the structure, the default settings (the same than the ones set by the criAtomEx3dSource_SetDefaultConfig macro) are used to calculate the size of the work buffer.
If this function fails to calculate the size of the work buffer, it will return -1.
To know the reason of the failure, refer to the error callback message.
message.

Remarks:

The information in the config argument is referenced only within the function.
Since it will not be referenced after the function exits, it is okay to free the config area after the function is executed.

CriAtomEx3dSourceHn 3D sound source handle

Description:

Creates a 3D sound source based on the value of the parameters of the configuration structure.
When this function creates a 3D sound source successfully, it returns a handle.
When creating a 3D sound source, you must pass a work buffer.
The size of that buffer is calculated by calling the criAtomEx3dSource_CalculateWorkSize function.
(If a user-allocator has already been registered by using the criAtomEx_SetUserAllocator macro, you do not need to pass the work buffer.)

参数

[in]

ex_3d_source

3D sound source handle

Description:

Updates a 3D sound source with the parameters previously specified with other functions.
This function updates all the parameters specified for the 3D sound source at once.
Updating the 3D sound source with this function every time you change a single parameter is inefficient. You should update it after changing all the parameters you need to change.

Example:

CriAtomExVector pos;
CriAtomExVector vel;
 
// Set position
pos.x = 0.0f
pos.y = 0.0f
pos.z = 1.0f
criAtomEx3dSource_SetPosition(source, &pos);
// Set velocity
vel.x = 1.0f
vel.y = 0.0f
vel.z = 0.0f
criAtomEx3dSource_SetVelocity(source, &vel);
 
// Update source parameters
criAtomEx3dSource_Update(source);

注意

This function works independently from the parameter update functions ( criAtomExPlayer_UpdateAll and criAtomExPlayer_Update). Whenever you change the parameters of a 3D sound source, use this function to update them.

[in]	front	Forward vector
[in]	top	Up vector

Description:

Sets the orientation of the specified 3D sound source.
The direction set by this function will be set as the direction of the sound cone.
The sound cone represents the direction from which sound emanates from a sound source and is used to describe the directionality of sound.
The direction of the sound cone is specified as a three-dimensional vector. The set direction vector is normalized and used within the library.
Since the direction of the sound cone cannot be set on the data side, the value set by this function is always used.
The default values are as follows:

• Forward vector : (0.0f, 0.0f, 1.0f)
• Up vector : (0.0f, 1.0f, 0.0f)

Remarks:

When setting the sound cone orientation, the up vector is ignored and only the forward vector is used.
Also, if you are using Ambisonics playback, the Ambisonics will rotate according to the orientation specified by this function and the orientation of the listener.

注意

To actually apply the specified values, you have to call the criAtomEx3dSource_Update function.
It is not possible to apply a sound cone to Ambiosnics.

[in]	inside_angle	inside angle of the sound cone
[in]	outside_angle	outside angle of the sound cone
[in]	outside_volume	outside volume of the sound cone

Description:

Sets the parameters of the sound cone of the 3D sound source.
A sound cone represents the orientation of the sounds generated from a sound source, and is used to represent the directivity of sounds.
A sound cone consists of inside and outside cones. insideAngle indicates the angle of the inside cone, and outsideAngle indicates the angle of the outside cone. outsideVolume indicates the volume at an angle that is greater than or equal to the angle of the outside cone.
When the sound source angle is smaller than the angle of the inside cone, no attenuation occurs due to the cone. At an angle between the inside and outside cones, the volume gradually decreases towards the outside volume.
For the inside and outside angles, specify a degree from 0.0f to 360.0f.
The outside volume is specified as a scaling factor between 0.0f and 1.0f (the unit is not decibel).
The default values at the initialization of the library are as follow (no attenuation occurs due to the cone).

• Inside angle: 360.0f
• Outside angle: 360.0f
• Outside volume: 0.0f

The default values can be changed by calling the criAtomEx3dSource_ChangeDefaultConeParameter function.
If the sound cone parameters are set on the data side, the parameters are evaluated as follows when this function is called.

• Inside angle: Addition
• Outside angle: Addition
• Outside volume: Multiplication

注意

To actually apply the specified parameters, call the criAtomEx3dSource_Update function.

For default values at library initialization, see criAtomEx3dSource_SetConeParameter function.

注意

For this parameter, the default value is implicitly applied for "not changed by tool" (default state) data.

[in]	min_attenuation_distance	minimum distance
[in]	max_attenuation_distance	maximum distance

Description:

Sets the minimum and maximum attenuation distances for a 3D sound source.
The minimum distance represents the distance below which the volume is maximum. The maximum distance represents the distance at which the minimum volume is reached.
The default values at the initialization of the library are as follows:

• Minimum distance: 0.0f
• Maximum distance: 0.0f

The default values can be changed by calling the criAtomEx3dSource_ChangeDefaultMinMaxAttenuationDistance function.
If the parameter is set on the data side (i.e. in the tool), the values of the data are overwritten (ignored) when this function is called.

注意

To actually apply the specified values, you have to call the criAtomEx3dSource_Update function.

参数

[in]	ex_3d_source	3D sound source handle
[in]	source_radius	Radius of 3D sound source
[in]	interior_distance	Interior distance

Description:

Sets the interior panning boundaries of a 3D sound source.
The radius of the 3D sound source corresponds to the sound source being considered as a sphere.
The interior distance is the distance from the radius of the 3D sound source applied to the interior panning.
Interior panning is applied within the radius of the 3D sound source, but since the interior distance is treated as 0.0, sound is played at the same volume from all the speakers.
Within the interior distance, interior panning is applied.
Outside the interior distance, interior panning is not applied, and audio is played from the one or two speakers closest to the sound source location.
The default values at library initialization are as follows.

• Radius of 3D sound source : 0.0f
• Interior distance : 0.0f (Depends on minimum distance of 3D sound source)

The default value can be changed with the criAtomEx3dSource_ChangeDefaultInteriorPanField function.
Since this parameter can not currently be set in the tool, the value set with this function is always used.

注意

In order to actually apply these parameters, you need to call the criAtomEx3dSource_Update function.

参数

[in]	ex_3d_source	3D sound source handle
[in]	doppler_factor	Doppler factor

Description:

Sets the Doppler factor for a 3D sound source.
The Doppler factor is a scale factor to exaggerate the Doppler effect, which is calculated based on a sound velocity of 340 m/s.
For example, if you specify 2.0f, the pitch that is calculated based on a sound velocity of 340 m/s is doubled.
If you specify 0.0f, the Doppler effect is disabled.
The default value at the initialization of the library is 0.0f.
The default value can be changed using the criAtomEx3dSource_ChangeDefaultDopplerFactor function.

Specify a real number of 0.0f to 1.0f for the volume value.
The volume is a scaling factor for the amplitude of the sound data (the unit is not decibel).
For example, if you specify 1.0f, the volume of the original sound is maintained.
If you specify 0.5f, the amplitude of the original sound is halved (i.e. the volume is -6 dB).
If you specify 0.0f, the sound is muted (silent).
The default value at the initialization of the library is 1.0f.
The default value can be changed with the criAtomEx3dSource_ChangeDefaultVolume function. If the volume of the 3D sound source is set on the data side and this function is called, the result of the multiplication between the volume from the data and the volume passed to the function will be applied.

注意

To actually apply the specified value, you have to call the criAtomEx3dSource_Update function.

Change the default volume of a 3D sound source

参数

[in]

volume

volume

Description:

Changes the default volume of a 3D sound source.
If you change the default value by this function, the initial value of the volume of the 3D sound source handle ( CriAtomEx3dSourceHn ) to be created later becomes the value set by this function.
For default values at library initialization, see criAtomEx3dSource_SetConeParameter function.

注意

When the relevant parameter is not set in the tool, the default value is used implicitly.
Therefore, if you change the default value, the parameter may be different than what was intended.
However, data built for in-game preview is not affected by this function.

参数

[in]

返回

max_delta maximum variation of the angle AISAC control value

Description:

Sets the maximum variation when the AISAC control value is changed by the angle AISAC.
When the maximum variation is set to a small value, the angle AISAC changes the AISAC control value smoothly, even if the relative angle between the sound source and the listener is changed sharply.
For example, if you set (0.5f / 30.0f), 30 frames are used to change the angle from 0 degrees to 180 degrees.
The default value is 1.0f (no restriction).
The value set by this function is always used, because this parameter cannot be set on the data side.

注意

To apply the specified value, you have to call the criAtomEx3dSource_Update function.
The maximum variation set by this function is applied only to the change in the angle AISAC control value that is calculated based on the localization angle. It does not affect the localization angle itself.

参数

[in]	ex_3d_source	3D Sound Source Handle
[in]	func	Callback function for calculating position coordinates in 3D sound source randomization
[in]	obj	User-specified objects

Description:

For 3D sound sources, register a callback function for calculating position coordinates when randomizing the position of the 3D sound source.
If randomization of the 3D sound source position is enabled, the registered callback function will be executed when the coordinates are calculated.

Remarks:

The specified callback function will be executed when calculating coordinates only if CRIATOMEX3DSOURCE_RANDOM_POSITION_CALCULATION_TYPE_CALLBACK is set for the calculation_type variable of CriAtomEx3dSourceRandomPositionConfig, which is a configuration structure for randomizing the position of the 3D sound source.

注意

The criAtomEx3dSource_Update function must be called to apply the callback registration.

If you execute an API that does not take into account interrupts to server processing, an error or deadlock may occur.
Generally, you should not use any Atom Library APIs within your callback functions.
Please note that if you block processing within this callback function for a long period of time, problems such as sound dropouts may occur.

Only one callback function can be registered for each 3D sound source handle.
If you perform the registration operation multiple times, the callback function that has already been registered will be overwritten by the callback function registered later.

You can unregister a registered function by specifying NULL for func.

Description:

Get the size of the work area required to create a 3D sound source handle list.
When creating a 3D sound source handle list without having registered an allocator, it is necessary to call the criAtomEx3dSourceList_Create function with the right size for the work area.

The size of the work memory required to create the 3D sound source handle list varies depending on the contents of the 3D sound source handle list creation configuration structure ( CriAtomEx3dSourceListConfig ).

When NULL is specified as an argument, the work area size is calculated from the default settings. ( criAtomEx3dSourceList_SetDefaultConfig )
If the work area size calculation fails, the return value is -1.
The reason why the work area size calculation failed can be confirmed with the error call back message.

Remarks:

The information passed in the argument "config" is only referenced within this function.
Therefore it is safe to release the "config" area after executing the function.

返回值

>=	0 Successfully completed

Description:

Calculates the size of the work buffer required to create a 3D listener.
If you create a 3D listener without having registered a user-allocator, a memory buffer having the size returned by this function must be passed to criAtomEx3dListener_Create.

The size of the work buffer needed to create a 3D listener depends on the value of the parameters in the configuration structure ( CriAtomEx3dListenerConfig ).

When NULL is specified for the structure, the default settings (the same than the ones set by the criAtomEx3dListener_SetDefaultConfig macro) are used to calculate the size of the work buffer.
If this function fails to calculate the size of the work buffer, it will return -1.
To know the reason of the failure, refer to the error callback message.

Description:

Updates a 3D listener with the parameters previously specified with other functions.
This function updates all the parameters specified for the 3D listener at once.
Updating the 3D listener with this function every time you change a single parameter is inefficient. You should update it after changing all the parameters you need to change.

Example:

CriAtomExVector pos;
CriAtomExVector vel;
 
// Set position
pos.x = 0.0f
pos.y = 0.0f
pos.z = 1.0f
criAtomEx3dListener_SetPosition(source, &pos);

criAtomEx3dListener_SetFocusPoint()

void criAtomEx3dListener_SetFocusPoint	(	CriAtomEx3dListenerHn	ex_3d_listener,
		const CriAtomExVector *	focus_point
	)

Set the focus point of the 3D listener

参数

[in]	ex_3d_listener	3D listener handle
[in]	focus_point	focus point vector

Description:

Sets the focus point of a 3D listener.
When performing 3D positioning, setting a focus point connects the listener position and the focus point with a straight line along which the microphone can be moved.
For example, you can easily represent and adjust objective and subjective situations by setting a focus point on the main character while keeping the listener and the camera sychronized.
Note that the microphone that can be moved between the listener position and focus point differs from real-world microphones in that its distance sensor (for distance attenuation calculation) and direction sensor (for localization calculation) are independent.
By operating the sensors separately, you can achieve effects such as setting the focus on the main character and performing distance attenuation based on the character position, or performing localization calculation based on the camera position to match localization with the view point on the screen.
The default value is (0.0f, 0.0f, 0.0f). When the focus levels of the distance sensor and direction sensor are not set, there is no need to set a focus point. In that case, all 3D positioning calculations are performed based on the listener position as usual.

	)

Set the focus level of the distance sensor

参数

[in]	ex_3d_listener	3D listener handle
[in]	distance_focus_level	focus level of the distance sensor

Description:

Sets the focus level of the distance sensor.
The distance sensor represents the reference position used to calculate the distance attenuation for the 3D positioning. It can be considered as a microphone that only detects the effect of the distance attenuation and ignores localization.
The focus level represents how close the sensor (microphone) can be brought to the focus point. The sensor (microphone) can be moved along the line connecting the listener position and the focus point, with 0.0f and 1.0f corresponding to the listener position and the focus point, respectively.
For example, when the focus level of the distance sensor is set to 1.0f and the focus level of the direction sensor is set to 0.0f, the distance attenuation is applied based on the focus point, and the localization is determined based on the listener position.
The default value is 0.0f. When the focus levels of the distance and direction sensors are not set, all 3D positioning calculations are performed based on the listener position as usual.

Set the focus level of the direction sensor

参数

[in]	ex_3d_listener	3D listener handle
[in]	direction_focus_level	focus level of the direction sensor

Description:

Sets the focus level of the direction sensor.
The direction sensor represents the reference position used to calculate the localization for the 3D positioning. It can be considered as a microphone that only detects localization and ignores distance attenuation.
For the orientation of the direction sensor, the orientation of the listener is used (set by the criAtomEx3dListener_SetOrientation function).
The focus level represents how close the sensor (microphone) can be brought to the focus point. The sensor (microphone) can be moved along the line connecting the listener position and the focus point, with 0.0f and 1.0f corresponding to the listener position and the focus point, respectively.
For example, when the focus level of the distance sensor is set to 1.0f and the focus level of the direction sensor is set to 0.0f, the distance attenuation is applied based on the focus point, and the localization is determined based on the listener position.

Description:

Sets the interior panning boundary distance for 3D transceiver output.
The radius of the 3D transceiver output is the radius when the 3D transceiver output is a sphere.
Interior distance is the distance from the radius of the 3D transceiver that interior panning is applied.
Within the radius of the 3D transceiver, interior panning is applied, but since the interior distance is treated as 0.0, sound will be played at the same volume from all speakers.
Within the interior distance, interior panning is applied.
Outside the interior distance, no interior panning is applied and the sound is played from the one or two speakers closest to the 3D transceiver position.

Description:

Set the crossfade boundary distance of 3D transceiver input.
Within the radius of the direct sound area, the sound from the output of the 3D transceiver is not played, only the sound from the 3D sound source is played.
The crossfade distance is the distance from the direct sound area where the crossfade of the 3D transceiver output and the sound from the 3D source is applied.
In the direct sound area, the rate of crossfade is 1 from the sound source and 0 from the 3D transceiver, so the sound from the 3D transceiver output cannot be heard, and only the sound from the sound source is played.
Within the crossfade distance, a crossfade will be applied depending on the position of the listener.
Outside the crossfade distance, you will not hear audio from the 3D source, only the audio from the 3D transceiver output.
The default values at library initialization are as follows:

• Radius of direct sound area:0.0f

	)

Setting the volume of the 3D transceiver output

参数

[in]	ex_3d_transceiver	3D Transceiver handle
[in]	volume	Volume

Description:

Sets the volume of the 3D transceiver output.
The volume of the 3D transceiver output affects only the volume related to localization (L, R, SL, SR) and does not affect the output level to the LFE or the center.
For the volume value, specify a real value in the range 0.0f-1.0f.
The volume value is a scale factor for the amplitude of audio data (the unit is not decibel).
For example, if you specify 1.0f, the original sound will be output with the same volume.
When 0.5f is specified, the sound is output at the same volume (-6dB) as the data in which the amplitude of the original sound waveform is halved.
If you specify 0.0f, the audio will be muted (silent).
The default value at library initialization is 1.0f.

注意

In order to actually apply the set parameters, you need to call the criAtomEx3dTransceiver_Update function.

criAtomEx3dTransceiver_AttachAisac()

void criAtomEx3dTransceiver_AttachAisac	(	CriAtomEx3dTransceiverHn	ex_3d_transceiver,
		const CriChar8 *	global_aisac_name
	)

Attach AISAC to 3D transceiver

参数

[in]	ex_3d_transceiver	3D Transceiver handle
[in]	global_aisac_name	Global AISAC name

Description:

Attach AISAC to 3D transceiver. By attaching AISAC, you can get the effect of AISAC even if you have not set AISAC for the cue or track.

If the AISAC attach fails, an error callback will occur in the function.
Check the error callback message for the reason why the AISAC attach failed.

Remarks:

Only the global AISAC included in the global settings (ACF file) can be attached.
To get the effect of AISAC, it is necessary to set the appropriate AISAC control value as well as the AISAC set for the cue or track.

注意

Even if "AISAC to change AISAC control value" is set for the cue or track, the applied AISAC control value does not affect the AISAC attached to the 3D transceiver.
Currently, it does not support control type AISAC attachment such as "automodulation" or "random".
Currently, the maximum number of AISACs that can be attached to a 3D transceiver is fixed at 8.

Detach AISAC from 3D transceiver

参数

[in]	ex_3d_transceiver	3D Transceiver handle
[in]	global_aisac_name	Global AISAC name

Description:

Detach the AISAC from the 3D transceiver.

If AISAC detach fails, an error callback will occur in the function.
Check the error callback message for the reason why the AISAC detach failed.

void criAtomEx3dTransceiver_SetMaxAngleAisacDelta	(	CriAtomEx3dTransceiverHn	ex_3d_transceiver,
		CriFloat32	max_delta
	)

Setting of maximum change amount of angle AISAC control value

参数

[in]	ex_3d_transceiver	3D Transceiver handle
[in]	max_delta	Maximum change in angle AISAC control value

Description:

Sets the maximum change amount when the AISAC control value is changed by the angle AISAC.
By changing the maximum change amount to a lower value, the change of the AISAC control value by the angle AISAC can be made smooth even if the relative angle between the 3D transceiver and the listener changes rapidly.
For example, if (0.5f/30.0f) is set, the change amount will change over 30 frames when the angle changes from 0 to 180.
The default value is 1.0f (no limit). Since this parameter cannot be set on the data side, the setting value of this function is always used.

注意

In order to actually apply the set parameters, you need to call the criAtomEx3dTransceiver_Update function. The maximum change amount set by this function is applied only to the change of the angle AISAC control value calculated based on the localization angle. It does not affect the localization angle itself.

参数

[in]	ex_3d_transceiver	3D Transceiver handle
[in]	aisac_control_id	Distance AISAC control ID

Description:
