Procedural Music Generator abandoned

Engine Sound Generator is a procedural audio synthesis tool that generates physically-modeled engine sounds using the Web Audio API. It implements waveguide-based synthesis techniques derived from research on physically informed car engine sound synthesis, simulating intake, exhaust, and engine block vibrations with configurable parameters like cylinder count, waveguide lengths, and reflection factors. The tool offers multiple implementations including a JavaScript AudioWorklet version and a WebAssembly-compiled version for improved performance. It integrates with Three.js for spatial audio positioning and includes Doppler effect simulation using DelayNodes. Parameters like RPM, muffler configurations, and individual component volumes can be adjusted in real-time. The WebAssembly version eliminates audio glitches present in pure JavaScript implementations while maintaining the same API surface. All synthesis is done procedurally without sample playback, making it suitable for dynamic vehicle simulations where engine characteristics need to change based on gameplay state.

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.

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.

KinetiTone

Standalone

KinetiTone is a browser-based generative sound designer targeting game developers and sound designers who need quick SFX prototyping and production without a DAW or local installation. It provides six synthesis engines (Classic, FM, Additive, Wave, Noise, Physical), up to four simultaneous layers, a six-slot effects chain, and a randomize/mutate system for rapid sound exploration. A seed system lets you reproduce any generated sound exactly, and a batch export feature can generate variations downloaded as a ZIP of WAV files. Sound history with waveform previews and favorites keeps your session organized. Sounds you create are yours to use in commercial or non-commercial projects; the stated restriction is that you may not resell the generated sounds as-is. It is a closed-source HTML5 web app hosted on itch.io with no public source repository, so there is no license file and no self-hosting option.
