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.

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.

ArcadeAudioKit

Standalone · Engine-agnostic

ArcadeAudioKit is a Swift package for modeling and rendering short synthesized sound effects on Apple platforms (iOS 18+, macOS 12+, tvOS 18+, watchOS 11+, visionOS 2+). It provides a recipe-based API: you describe a sequence of waveform segments (sine, triangle, or square), each with pitch (scientific notation notes, Hz values, sweeps, or interpolated pitch), timing, amplitude, attack, and decay. The renderer converts that recipe into deterministic mono Float PCM samples at a caller-specified sample rate. The library deliberately stops at PCM output. Audio session management, AVFoundation integration, mixing policy, playback, and accessibility behavior are left entirely to the consuming app. This makes it suitable as a dependency in games or game engine extensions where you want reproducible procedural SFX without taking on a full synthesis framework. v1 scope is narrow: recipe modeling, note-to-Hz conversion via A4=440, repeated motif generation for tails and loops, and the PCM renderer. Requires Swift 6.2+ and has no external dependencies.

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.
