Game audio pipeline
From scratch sounds to maintainable interactive audio
Cover cleanup, sourcing, synthesis, mixing, and runtime integration so audio stops being a one-off patch at the end of production.
01
The problem to solve
Small games often carry untracked scratch sounds deep into production, then pay for it through volume, looping, licensing, and trigger rework. This collection treats source records, non-destructive editing, and runtime events as one pipeline that programmers, artists, and audio collaborators can review together.
Selection criteria
Why these tools belong together
02
Revisable editing
Prefer project files, original recordings, and saved processing chains over a single flattened file that cannot be remixed or repaired.
Testable runtime behavior
Music layers, random variants, attenuation, and buses need repeatable game-state tests rather than approval inside the audio editor alone.
Recommended workflow
Prove the path before scaling production
03
Build an event inventory
List player actions and scenes by feedback priority, marking placeholders, original work, licensed acquisitions, and genuinely dynamic requirements.
Set a source and loudness baseline
Preserve originals, agree on cleanup and loop conventions, then use representative scenes to balance dialogue, music, and effects.
Move variation into events and parameters
Add variants and bounded pitch or level changes to frequent sounds, and drive music or ambience from explicit game states.
Stress-test target devices
Verify voice counts, memory, streaming, suspend and resume, and different output devices while preserving a reproducible mix reference.
Selected resources
Build the smallest useful combination from these six
These tools divide cleanup, production, sourcing, synthesis, and interactive integration. Start with a traceable minimum pipeline, then add middleware only when event complexity justifies it.
