Sound

OpenAL Soft

Patch 3374 for Unreal Tournament 2004 replaces the legacy DirectSound-based OpenAL with OpenAL Soft, modernizing the game’s audio backend for improved compatibility, stability, and 3D positional sound on current systems.

Audio Features & Options

• HRTF support – Enhanced 3D positional audio for headphones
• Selectable HRTF modes – Enable/disable and profile selection
• Playback device selection – Choose specific output devices
• Stereo / 5.1 / 7.1 support – Improved surround handling
• Sample rate & resampler settings – Quality/performance tuning
• Ambisonics support – B-Format decoding for advanced spatial audio workflows
• Configurable decoders & backends – Select output backends (e.g., WASAPI, PulseAudio, PipeWire) and decoder behavior

Configuration files

Audio behavior can be customized through files containing settings for different use cases (e.g., competitive HRTF headphones, high-quality surround, low-latency setup).

You can place the file next to the game executable and OpenAL Soft will override the system or user config Common adjustable options include:

• hrtf = true/false
• frequency = <sample rate>
• channels = stereo / 5.1 / 7.1
• resampler = <type>
• period_size and periods (latency tuning)
