ChipForge — Procedural Retro SFX & Music for Unity

Every sound. Zero audio files.

ChipForge synthesizes retro-style sound effects and looping music directly at runtime in Unity. Sounds are small data assets you tweak in the Inspector with instant live preview — no play mode, no .wav files, no dependencies.

WHAT YOU GET

- 12 ready-made SFX presets: Coin, Jump, Laser, Explosion, Powerup, Fanfare, Hit, UI Click, Confirm, Cancel, Notification, Game Over

- 6 music moods as seamless loops with automatic crossfade: Menu, Calm, Chill, Dark, Epic, Energetic

- 5 waveforms (sine, square, triangle, saw, noise), pitch sweeps, envelopes, noise color

- One-line API: SfxPlayer.Play(recipe); / MusicPlayer.Play(mood);

- Volume & mute persistence built in

- Full C# source code + PDF manual

- Interactive demo scene (Tools > ChipForge > Add Demo To Scene)

WHY IT'S DIFFERENT

Everything is generated in code at the device's sample rate — your build stays tiny (the whole package is under 40 KB) and you keep full control over every sound. Tested on Windows and Android; works with Built-in, URP and HDRP.

FAQ

- Do I need to be an audio expert? No. Start from the presets and tweak by ear with live preview.

- Can I use it in commercial games? Yes — unlimited personal and commercial projects (per-seat license, see LICENSE.txt).

- Will it bloat my build? No — zero asset weight, it's just a few KB of code.

- Is this a full DAW or orchestral music engine? No — ChipForge is focused on retro/chiptune-style SFX and looping music. That focus is what keeps it tiny and simple.

REQUIREMENTS

Built and tested with Unity 6 (6000.4). No packages required — the optional demo uses Unity UI (com.unity.ugui) if present.
