A data asset wrapping FSoundAttenuationSettings that controls how a sound's volume, spatialization, air absorption, reverb send, and occlusion change with listener distance.
The abstract base class for all playable sound assets.
A hierarchical category asset that groups sounds and applies shared volume, pitch, reverb, and submix routing.
A graph-based audio asset that combines SoundWaves with nodes for mixing, randomization, looping, pitch modulation, and sequencing.
Applies temporary volume, pitch, and EQ adjustments to specified SoundClasses when pushed to the audio device.
A raw audio asset imported from a WAV file.
Removes a per-class volume/pitch override that was previously applied to a Sound Mix via SetSoundMixClassOverride, fading back to the unoverridden values.
Immediately removes all active Sound Mix Modifiers from the audio system regardless of their push counts.
Creates a non-spatialized, non-attenuated UAudioComponent without immediately starting playback, useful when you need to configure the component before playing.
Retrieves the current-time amplitude envelope value for each sound wave playing on the component individually, without averaging across sounds.
Retrieves cooked FFT spectral data separately for each sound wave currently playing on the component, without averaging across sounds.
Returns the USoundBase currently assigned to this component's Sound property.
Plays a non-spatialized (2D) sound that is not affected by the listener's position or orientation.
Plays a one-shot sound at a world position with 3D attenuation.
Decrements the active count of a Sound Mix Modifier and deactivates it when the count reaches zero.
Iterates all streaming sound waves belonging to the given sound class and caches their first audio chunk to reduce first-play hitches.
Pre-caches the first compressed audio chunk of a streaming sound to eliminate the hitch that occurs the first time it plays.
Activates a Sound Mix Modifier on the audio system, applying its volume and pitch adjustments to the Sound Classes it targets.
Sets the active base sound mix for the audio engine, applying the EQ and volume/pitch adjustments defined in the mix asset globally.
Changes which USoundBase this component will play, replacing the current value of the Sound property.
Scales the attenuation distance of all sounds belonging to a given SoundClass, optionally interpolating over time.
Adds or replaces a sound class adjuster in an active sound mix at runtime, allowing volume and pitch of an entire sound class to be changed dynamically with a smooth fade.
Marks sounds generated by this component as UI sounds, which typically exempts them from 3D spatialization, world pausing, and gameplay volume ducking.
Spawns an audio component that plays a non-spatialized (2D) sound with no attenuation.
Spawns a spatialized audio component at a fixed world location and begins playback immediately.
Spawns a spatialized UAudioComponent attached to a scene component so it follows it through the world.
Releases the retained streaming chunk handles for all sound waves in the given sound class, making those chunks eligible for eviction from the audio streaming cache.
Activates the component, which for UAudioComponent begins playing the assigned Sound if bAutoActivate is set or Activate() is called explicitly.
Binds a native C++ delegate that fires when the specified state in an animation state machine is entered.
Returns the assigned Sound asset so it appears alongside this component's name in editor stat/debug displays (e.
Overrides this component's attenuation settings with a custom settings struct, bypassing any shared USoundAttenuation asset reference.
Smoothly ramps the sound instance's playback volume to a new level over a given duration, using the chosen fade curve.
Shared implementation behind AdjustVolume, FadeIn, and FadeOut that queues a volume interpolation on the component's active sound.
Returns true if at least one audio listener (typically the player camera) is within MaximumRange of Location.
A reusable USoundAttenuation asset that defines distance-based volume falloff and spatialization for this component's sound.
Gathers the attenuation shapes applicable to this component's sound into a multimap, keyed by shape type, for editor or in-game debug visualization.
The set of USoundConcurrency rules applied to sounds generated by this component, controlling how many instances can play simultaneously and which get cut off when limits are exceeded.
Deactivates the component, which for UAudioComponent stops the currently playing sound if one is active.
Called when the audio component's owning actor ends play, allowing it to stop its sound and clean up before the component or its owner is destroyed.
Starts the sound and ramps volume from 0 to FadeVolumeLevel over FadeInDuration seconds.
Smoothly ramps the playing sound's volume down to FadeVolumeLevel over FadeOutDuration seconds.
Returns the USoundAttenuation asset referenced by this component's AttenuationSettings property, regardless of whether bOverrideAttenuation is enabled.
Returns a pointer to the attenuation settings that will be used for this component's sounds — either the AttenuationOverrides struct or the settings from the referenced AttenuationSettings asset, depending on bOverrideAttenuation.
Returns the unique instance ID assigned to this audio component, used internally to correlate it with active sounds on the audio render thread.
Returns the audio device this component's sounds are being rendered through, implementing the ISoundParameterControllerInterface accessor.
Retrieves the amplitude envelope value at the current playback time, averaged across all sound waves currently playing on the component.
Retrieves cooked spectral (FFT) data at the current playback time for the requested frequencies.
Returns a string describing this component's current sound asset, used by the editor and log tooling that displays detailed UObject info (e.
Returns whether this component ignores parameter updates for sounds that are already playing, mirroring the bDisableParameterUpdatesWhilePlaying property.
Returns this component's unique AudioComponentID, used by the ISoundParameterControllerInterface to identify which owner a set of runtime parameters belongs to.
