16bits-audio-mcp

Standalone · Engine-agnostic

16bits-audio-mcp is a Zig-based MCP server that exposes game audio generation as tools callable by Claude. It produces 16-bit PCM WAV files using FM synthesis, reverb, ADSR envelopes, and multi-track mixing, all from the Zig standard library with zero external dependencies. It covers three asset types: BGMs in 15 styles (adventure, dungeon, boss, cyber, horror, etc.) with 4-track arrangements; 20 sound effect types (jump, coin, explosion, laser, etc.) with pitch and volume control; and 12 jingle types for common game events like stage clear and game over. Scales, tempo, key, and a deterministic seed parameter give reproducible iteration. A post-processing tool (wav_fx) chains effects such as reverb, delay, bitcrusher, chorus, and distortion, and a mixer tool combines multiple WAV files. Additional tools handle direct note/FM synthesis, WAV info, and playback. The workflow is prompt-driven: describe what you want to Claude, and WAV files are written to disk.

Audio Agent Creator

Standalone · Engine-agnostic

Audio Agent Creator is a Go-based offline audio synthesis engine designed for programmatic use by game agents or automation scripts. It takes a JSON project description (or a named preset) and deterministically renders stereo PCM, then encodes to 192 kbps MP3 via FFmpeg/libmp3lame or exports lossless PCM16 WAV. The synthesis chain supports oscillators (sine, square, saw, triangle, noise), frequency sweeps, ADSR envelopes, per-track volume/pan/transpose/mute, first-order low-pass/high-pass filters, and basic feedback delay. The tool exposes three interfaces sharing the same project DSL and render contract: a CLI with commands for generation, validation, preset inspection, and schema export; an HTTP API with synchronous and async job endpoints; and a Vite/React web workbench for JSON import, server-side validation, job submission, and MP3/WAV playback. Eight built-in presets (6 SFX, 2 BGM) provide deterministic starting points. This is explicitly an agent-first SFX/BGM MVP, not a DAW replacement. It has no MIDI, piano roll, sampler, plugin host, mixer bus, or generative AI music model. The prompt field currently uses keyword heuristics to select presets rather than text-to-audio synthesis.

Audio Asset Lab

Engine-agnostic · Standalone

Audio Asset Lab is a local, YAML manifest-driven pipeline for producing sound effects and music for games, video, and web projects. You describe generation parameters, seeded variants, post-processing steps, and export formats in a single versionable manifest; the tool produces candidate audio files, selected lossless masters, delivery exports (WAV, OGG, MP3), and provenance records containing prompts, model revisions, processing chains, licenses, and hashes. Two generation paths are available: a deterministic procedural engine (no model weights, included by default) for tonal UI cues, jingles, and synthetic effects; and optional Stable Audio 3 MLX engines (Apple Silicon only) for prompt-driven SFX, ambience, and music. Three model variants are supported: stable-audio-3-small-sfx, stable-audio-3-small-music, and stable-audio-3-medium. Consumer repositories receive only the delivery audio files and have no dependency on the pipeline, Python environment, or any model runtime. Builds are seed-addressed and refuse to overwrite existing outputs without an explicit --force flag. The CLI exposes engine routing and the manifest schema via JSON flags to support agent-assisted manifest authoring. The project is described as usable but early; the manifest and CLI are the stable interface.

barelyMusician

Unity · Godot · Engine-agnostic

barelyMusician is a real-time music engine designed for interactive systems that generates and performs musical sounds programmatically with sample-accurate timing. It provides a modern C/C++ API for creating instruments, performers, and musical tasks that can be sequenced and synchronized precisely. The engine supports procedural note control, tempo management, looping performers, and task-based event scheduling. It processes audio synchronously and is designed for integration into real-time audio applications where predictable timing and low latency are critical. The project includes native plugins for Unity and Godot, a VST instrument plugin, and builds for multiple platforms including Windows, macOS, Linux, Android, WebAssembly, and embedded hardware (Daisy). It offers an alternative to asset-based approaches when you need fully generative or algorithmically controlled musical content.
