FrontLeft

#Overview

name: FrontLeft

The value of this variable can be defined or overridden in .ini config files. 2 .ini config files referencing this setting variable.

It is referenced in 65 C++ source files.

#Summary

#Usage in the C++ source code

The purpose of FrontLeft is to represent the front left audio channel in Unreal Engine’s audio system. This setting variable is part of the EAudioMixerChannel enumeration, which defines various audio channel types used in spatial audio and multi-channel sound systems.

The FrontLeft variable is primarily used in the audio rendering and mixing systems of Unreal Engine.
Multiple subsystems and modules rely on this variable, including:
- AudioMixer
- AudioMixerCore
- SignalProcessing
- SoundFieldRendering
- Various platform-specific audio implementations (e.g., XAudio2, CoreAudio, AudioUnit)
The value of this variable is typically set as part of the audio channel configuration for output devices or when defining speaker layouts for different audio formats.
FrontLeft often interacts with other channel variables like FrontRight, FrontCenter, BackLeft, etc., to create complete channel configurations for various audio setups (e.g., stereo, 5.1, 7.1).
Developers should be aware that:
- FrontLeft is usually the first channel in most audio configurations.
- It’s essential for proper spatial audio rendering and channel mapping.
- Different platforms or audio APIs might have slightly different channel ordering, so proper mapping is crucial.
Best practices when using this variable include:
- Always consider the target platform’s audio capabilities and channel configurations.
- Use the appropriate channel mapping functions provided by Unreal Engine when working with multi-channel audio.
- Ensure proper channel ordering when creating or manipulating audio data to maintain correct spatial positioning.
- Test audio output on various speaker configurations to ensure correct channel assignment and spatial accuracy.
