Unigine.Plugins.FMOD.Channel Class
Notice
This set of functions is available when the FMOD plugin is loaded.
A source of audio signal that connects to the ChannelGroup mixing hierarchy.
Channel Class
Properties
float Pitch#
The the relative pitch or playback rate. Scales the playback frequency of a Channel object. The pitch value of 0.5f represents half pitch (one octave down), 1.0f represents unmodified pitch and 2.0f represents double pitch (one octave up).
float Frequency#
The frequency or playback rate. The default frequency is determined by the audio format of the Sound or DSP.
bool Paused#
The value indicating if the channel is paused.
int Priority#
The priority used for virtual voice ordering: 0 means the most important, 256 means the least important. The priority is used as a coarse grain control for the virtual voice system. Channels with the lower priority will always be stolen before Channels with the higher ones. For Channels of the equal priority, those with the quietest audibility value will be stolen first.
bool Mute#
The mute state. true for silent, false for audible.
int LoopCount#
The number of times to loop before stopping : 0 means oneshot, 1 means loop once then stop and -1 represents loop forever.
float Volume#
The volume level in range [-inf; inf]. 0 = silent, 1 = full. Negative level inverts the signal. Values larger than 1 amplify the signal.
bool VolumeRamp#
The value indicating if the volume changes are ramped or instantaneous. If not paused, volume changes are ramped to the target value to avoid a pop sound. This function allows you to override that setting and apply volume changes immediately.
bool IsPlaying#
The current playing state.
float Audibility#
The estimation of the output volume. The estimated volume is calculated based on 3D spatialization, occlusion, API volume levels and DSPs used. This value is used to determine which Channels should be audible and which Channels should be virtualized when resources are limited.
bool IsVirtual#
The the value indicating whether the Channel is being emulated by the virtual voice system. true means silent / emulated, false means audible / real.
int Index#
The index within the System Channel pool, a value from 0 to the total number of System Channels - 1.
Members
void Stop ( ) #
Stops the Channel (or all Channels in nested ChannelGroups) from playing.void SetMinMaxDistance ( float min, float max ) #
Sets the minimum and maximum distances used to calculate the 3D rolloff attenuation.Arguments
- float min - Distance from the source where attenuation begins. Range: [0; max]. Default: 1
- float max - Distance from the source where attenuation ends. Range: [min; inf]. Default: 10000.
void SetPosition ( vec3 position ) #
Sets the 3D position used to apply panning and attenuation.Arguments
- vec3 position - Position in 3D space used for panning and attenuation.
void SetPositionTimeLine ( uint position, FMODEnums.TIME_UNIT time_unit ) #
Sets the current playback position.Arguments
- uint position - Playback position.
- FMODEnums.TIME_UNIT time_unit - Time units for position.
void GetPositionTimeLine ( out uint position, FMODEnums.TIME_UNIT time_unit ) #
Returns the current playback position.Arguments
- out uint position - Playback position.
- FMODEnums.TIME_UNIT time_unit - Time units for position.
void Release ( ) #
Releases the channel object.void SetVelocity ( vec3 velocity ) #
Sets the velocity used to apply doppler.Arguments
- vec3 velocity - Velocity in 3D space used for doppler.
DSP AddDSP ( int index, DSPType.TYPE dsp_type ) #
Adds a DSP unit to the specified index in the DSP chain.Arguments
- int index - Offset into the DSP chain.
- DSPType.TYPE dsp_type - Type of the DSP.
Return value
Added DSP.void RemoveDSP ( int index ) #
Removes the specified DSP unit from the DSP chain.Arguments
- int index - Index of the DSP unit.
DSP GetDSP ( int index ) #
Returns the DSP unit at the specified index in the DSP chain.Arguments
- int index - Index of the DSP unit.
Return value
DSP unit at the specified index.void SetPan ( float pan ) #
Sets the left/right pan level.Arguments
- float pan - Pan level: -1 represents the full left, 0 represents the center, 1 represents the full right.
int GetNumDSPs ( ) #
Returns the number of DSP units in the DSP chain.Return value
The number of DSP units in the DSP chain.int GetIndex ( ) #
Returns the index of this object in the System Channel pool.Return value
The index within the System Channel pool, a value from 0 to the total number of System Channels - 1.Last update:
