Description

Audio Track Manager and AudioTrack objects for sound effects and music playback [v25.12.0].

Overview

The Audio Track module provides a unified audio system for loading and playing both short sound effects and long music tracks. Once the audio system is initialized using ConfigMgr::audioInit() or ConfigMgr::load(), you can load audio from external files, memory buffers, or CDC archives.
There are no longer fixed "channels". Tracks are allocated dynamically as needed, allowing for virtually unlimited polyphony (limited only by CPU/RAM).

Key features

Unified audio object: Handles both short SFX and long music streams transparently
Tag categorization: Tracks are assigned a category tag (Music, SFX, Voice, Custom) allowing group operations like "Stop all SFX" or "Fade out Music"
Hierarchical volume: Final Output Volume = Master Gain * Category Gain
Editor support: Optional raw data persistence for saving/exporting audio assets

AudioTrack actions

Playback	Play (supports multiple overlapping instances), stop, pause and resume
Transitions	Fade out and fade in on a given time
Playback control	Pitch/speed, looping, seeking (for streams)
Effects	Volume, panning, 3D distance and angular position

Loading strategies

Choose the appropriate loading strategy based on your audio content type and performance requirements:

Preload (RAM)	Best for SFX. Decodes entire file to memory for zero-latency playback
Stream (Disk)	Best for Music. Decodes chunks on-demand to save memory

Supported audio formats

Raw streams	AIFF, WAV and VOC
Compressed	FLAC, OGG and MP3
Modules (52)	669, abk, amf, arch, asylum, chip, coco, dbm, digi, dt, emod, far, flt, fnk, gal4, gal5, gdm, hmn, ice, imf, ims, it, liq, masi, masi16, mdl, med2, med3, med4, mfp, mgt, mmd1, mmd3, mod, mtm, muse, no, okt, pt3, ptm, rtm, s3m, sfx, st, stim, stm, stx, sym, ult, umx, xm, xmf

Manager type

This is a sharing manager: it has the ability of sharing an audio ID to a group of owners when they request to open an already opened object based on the name as the key.

Default behavior	Returns a shared ID. Control methods (stop/volume) affect all instances sharing this ID
Unique instance	Request via `load(..., iUnique=1)`. Creates a standalone object with independent control while efficiently sharing the underlying raw audio data in memory

Best practices

Always initialize the audio system via ConfigMgr::audioInit() or ConfigMgr::load() before using the Audio Track Manager
Leverage category tags (Music, SFX, Voice, Custom) for efficient group control operations
Consider the hierarchical volume model when setting levels: category and master gains are multipled
Request unique instances when you need independent playback control over the same audio asset
Access the manager exclusively through Main::IAudioTrackMgr()

Note: The Audio Track Manager is a singleton, automatically created once Main is instantiated. You can get a reference to this manager using Main::IAudioTrackMgr() method.
The Audio Track Manager is automatically released when Main::Terminate() is called. At this time, any resource still loaded will be released, avoiding resource leaks.
