Gorilla.Audio.FMOD.Intf.ChannelGroup

Stops the channel (or all channels in the channel group) from playing. Makes it available for re-use by the priority system.

Sets the wet level (or send level) of a particular reverb instance.

Parameters

• AInstance :  Integer  -  Index of the particular reverb instance to target, from 0 to FMOD_REVERB_MAXINSTANCES inclusive. Send level for the signal to the reverb, from 0 (none) to 1.0 (full), default = 1.0 for Channels, 0.0 for ChannelGroups. See remarks.
• AWet :  Single  -  Index of the particular reverb instance to target, from 0 to FMOD_REVERB_MAXINSTANCES inclusive. Send level for the signal to the reverb, from 0 (none) to 1.0 (full), default = 1.0 for Channels, 0.0 for ChannelGroups. See remarks.

Retrieves the wet level (or send level) for a particular reverb instance.

Parameters

• AInstance :  Integer  -  Index of the particular reverb instance to target, from 0 to FMOD_REVERB_MAXINSTANCES inclusive.

Sets a callback to perform action for a specific event.

Sets the pan level, this is a helper to avoid calling ChannelControl::setMixMatrix.

Parameters

• APan :  Single  -  Pan level, from -1.0 (left) to 1.0 (right), default = 0 (center).

Sets the speaker volume levels for each speaker individually, this is a helper to avoid calling ChannelControl::setMixMatrix.

Parameters

• AValue :  TGorillaFMODMixLevelsOutput  - 

  FrontLeft - Volume level for the front left speaker of a multichannel speaker setup, 0.0 (silent), 1.0 (normal volume).

  FrontRight - Volume level for the front right speaker of a multichannel speaker setup, 0.0 (silent), 1.0 (normal volume).

  Center - Volume level for the center speaker of a multichannel speaker setup, 0.0 (silent), 1.0 (normal volume).

  LFE - Volume level for the subwoofer speaker of a multichannel speaker setup, 0.0 (silent), 1.0 (normal volume).

  SurroundLeft - Volume level for the surround left speaker of a multichannel speaker setup, 0.0 (silent), 1.0 (normal volume).

  SurroundRight - Volume level for the surround right speaker of a multichannel speaker setup, 0.0 (silent), 1.0 (normal volume).

  BackLeft - Volume level for the back left speaker of a multichannel speaker setup, 0.0 (silent), 1.0 (normal volume).

  BackRight - Volume level for the back right speaker of a multichannel speaker setup, 0.0 (silent), 1.0 (normal volume).

Sets the incoming volume level for each channel of a multi-channel sound. This is a helper to avoid calling ChannelControl::setMixMatrix. A multi-channel sound is a single sound that contains from 1 to 32 channels of sound data, in an interleaved fashion. If in the extreme case, a 32ch wave file was used, an array of 32 floating point numbers denoting their volume levels would be passed in to the levels parameter, and 32 for the numlevels parameter.

Parameters

• const  ALevels :  TArray<System.Single>  -  Array of volume levels for each incoming channel. Number of levels in the array, from 0 to 32 inclusive.
• const  ANumlevels :  Integer  -  Array of volume levels for each incoming channel. Number of levels in the array, from 0 to 32 inclusive.

Retrieves the DSP clock values which count up by the number of samples per second in the software mixer, i.e. if the default sample rate is 48KHz, the DSP clock increments by 48000 per second.

Parameters

• var  ADSPClock :  UInt64  -  Address of a variable to receive the DSP clock value for the head DSP node. Address of a variable to receive the DSP clock value for the tail DSP node.
• var  AParentClock :  UInt64  -  Address of a variable to receive the DSP clock value for the head DSP node. Address of a variable to receive the DSP clock value for the tail DSP node.

Add a volume point to fade from or towards, using a clock offset and 0 to 1 volume level.

Parameters

• ADSPClock :  UInt64  -  DSP clock of the parent channel group to set the fade point volume. Volume level where 0 is silent and 1.0 is normal volume. Amplification is supported.
• AVolume :  Single  -  DSP clock of the parent channel group to set the fade point volume. Volume level where 0 is silent and 1.0 is normal volume. Amplification is supported.

Add a short 64 sample volume ramp to the specified time in the future using fade points.

Parameters

• ADSPClock :  UInt64  -  DSP clock of the parent channel group when the volume will be ramped to. Volume level where 0 is silent and 1.0 is normal volume. Amplification is supported.
• AVolume :  Single  -  DSP clock of the parent channel group when the volume will be ramped to. Volume level where 0 is silent and 1.0 is normal volume. Amplification is supported.

Remove volume fade points on the timeline. This function will remove multiple fade points with a single call if the points lay between the 2 specified clock values (inclusive).

Parameters

• ADSPClock_Start :  UInt64  -  DSP clock of the parent channel group to start removing fade points from. DSP clock of the parent channel group to start removing fade points to.
• ADSPClock_End :  UInt64  -  DSP clock of the parent channel group to start removing fade points from. DSP clock of the parent channel group to start removing fade points to.

Retrieve information about fade points stored within a Channel or ChannelGroup.

Retrieve the DSP unit at the specified index.

Parameters

• AIndex :  Integer  -  Offset into the DSP chain, see FMOD_CHANNELCONTROL_DSP_INDEX for special named offsets.

Add a pre-created DSP unit to the specified index in the DSP chain.

Parameters

• AIndex :  Integer  -  Offset to add this DSP unit at in the DSP chain, see FMOD_CHANNELCONTROL_DSP_INDEX for special named offsets. Interface to a pre-created DSP unit to be inserted at the specified offset (IGorillaFMODDSP).
• ADSP :  IGorillaFMODInterface  -  Offset to add this DSP unit at in the DSP chain, see FMOD_CHANNELCONTROL_DSP_INDEX for special named offsets. Interface to a pre-created DSP unit to be inserted at the specified offset (IGorillaFMODDSP).

Retrieves the number of DSP units in the DSP chain.

Moves the position in the DSP chain of a specified DSP unit.

Parameters

Adds a channel group as a child of the current channel group.

Parameters
