NIX Audio

Clip metadata, timed markers, pooled playback and an audio editor window for Unity.

Your game code passes an AudioClip. NIX Audio looks up its volume, random pitch, spatial blend, loop, mixer output, instance limit, cooldown and markers — named points in time that fire callbacks while the clip plays — and plays it on a prewarmed voice pool.

using NixAudio;

AudioPlayer.Instance.Load(combatLibrary);
AudioPlayer.Instance.Play(swordSwing, transform.position)
    .OnMarker("hit", ApplyDamage)
    .OnComplete(ReturnToIdle);
