Updates HOWTO.md with instructions for the --seek flag and assets/demo.seq editing. Updates CONTRIBUTING.md with the protocol for adding and registering new visual effects.
|
|
This adds a single CMake toggle to enable tools, tests, size optimizations, and code stripping, simplifying the development and verification workflow.
|
|
|
|
Adds instructions to HOWTO.md for re-generating assets from source audio using the provided script.
|
|
Introduces a 'final' target that automates the entire production pipeline: building the stripped binary, generating assets, and performing final compression (crunching).
- Updated CMakeLists.txt to define the 'final' target.
- Updated HOWTO.md with instructions for running 'cmake --build build --target final'.
|
|
Introduces a new asset management system to embed binary assets directly into the demo executable.
- Creates the directory for asset definition and an descriptor file.
- Implements to generate (with enum and declaration) and (with placeholder data).
- Integrates into CMake build, making depend on the generated asset files.
- Adds minimal integration in and documentation in .
This addresses Task 9 (compact in-line and off-line asset system).
|
|
Adds 'scripts/crunch_demo.sh' to automate building a stripped binary and compressing it with UPX.
Updates 'FETCH_DEPS.md' with UPX installation instructions and 'HOWTO.md' with usage guide.
This addresses Task 3 (add binary crunchers).

Adds a 'STRIP_ALL' mode to minimize binary size for the final build, and refines size optimization flags for macOS.
- **STRIP_ALL Mode**: Added a 'DEMO_STRIP_ALL' CMake option that defines 'STRIP_ALL'. In this mode, command-line parsing is bypassed (forcing fullscreen), debug labels/error callbacks are removed from WebGPU, and non-essential code (like iostream) is stripped.
- **macOS Optimizations**: Updated CMake to use '-dead_strip' instead of GNU '--gc-sections' on Apple platforms to resolve linker errors and improve dead code elimination.
- **Documentation**: Updated HOWTO.md to document the new 'Final / Strip Build' process and FETCH_DEPS.md for optimized wgpu-native build guidance.
- **Task 7 & 8**: Marks these tasks as completed in PROJECT_CONTEXT.md.

This commit fulfills tasks 1 and 2, and adds a synchronized visual effect.
- **Fullscreen Mode**: Added '--fullscreen' command-line argument and dynamic toggling via 'F' key.
- **Keyboard Controls**: Implemented 'Esc' to exit and 'F' to toggle fullscreen in 'src/platform.cc'.
- **Synchronized Visuals**: Added a pulsating heptagon effect in 'src/gpu/gpu.cc' and 'src/gpu/shader.wgsl' that scales and changes color based on the real-time audio peak from the synth.
- **Refactor**: Abstracted platform-specific WebGPU surface creation into 'src/platform.cc' to keep 'src/gpu/gpu.cc' cross-platform.
- **Build System**: Corrected 'CMakeLists.txt' to properly link 'wgpu-native' and platform frameworks, and updated 'project_init.sh' to build the submodule.
- **Documentation**: Updated 'HOWTO.md' and 'PROJECT_CONTEXT.md' with new features and decisions.

This commit introduces new tools for spectrogram manipulation and visualization, establishes a consistent coding style, and updates project documentation.
Key changes include:
- **Spectrogram Tools:
- : A command-line utility for analyzing WAV/MP3 files into custom spectrogram format and playing back these spectrograms via the synth engine.
- : A command-line tool for visualizing spectrogram files as ASCII art in the console.
- **Coding Style Enforcement:
- Added a configuration file enforcing LLVM-based style with 2-space indentation, no tabs, and an 80-column line limit.
- Renamed all C++ source files from to for project consistency.
- Applied automatic formatting using
exit across the entire codebase.
- **Documentation & Workflow:
- Created to define a commit policy requiring tests to pass before committing.
- Updated with instructions for building and using and , and referenced .
- Updated and to reflect the new tools, audio architecture decisions (real-time additive synthesis, double-buffering for dynamic updates, WAV/MP3 support), coding style, and development workflow.
- **Build System:
- Modified to:
- Include new targets for and under the option.
- Update source file extensions to .
- Add a new end-to-end test for to the suite.

Adds a new CTest unit test that performs a full, end-to-end verification of the 'spectool analyze' command.
The test programmatically generates a sine wave, saves it as a .wav file, executes the spectool executable as a subprocess to analyze the wave, and then verifies the integrity of the resulting .spec file.
This ensures the analysis pipeline (WAV decoding, windowing, FDCT, and file I/O) works correctly.
|
|
Leverages the built-in MP3 decoder in miniaudio to allow spectool's 'analyze' command to process .mp3 files in addition to .wav files.
Updates the tool's command-line help text and the project's HOWTO.md to reflect the new capability.
|
|
Adds a multi-voice, real-time audio synthesis engine that generates sound from spectrogram data using an Inverse Discrete Cosine Transform (IDCT).
Key features:
- A thread-safe, double-buffered system for dynamically updating spectrograms in real-time without interrupting audio playback.
- Core DSP components: FDCT, IDCT, and Hamming window functions.
- A simple sequencer in the main loop to demonstrate scripted audio events and dynamic updates.
- Unit tests for the new synth engine and Hamming window, integrated with CTest.
- A file documenting the build process, features, and how to run tests.
