Implements logic to remove unused trailing zero frames from spectrogram data before saving, reducing file size and improving loading efficiency.
|
|
|
|
Updates to prepend a warning comment to the generated and files, indicating they are auto-generated and should not be manually edited.
|
|
This refactors the asset management system to be more efficient and cleaner.
- Moved common GetAsset/DropAsset logic to src/util/asset_manager.cc.
- Changed retrieval to use an array of records (AssetRecord) for O(1) lookups instead of a switch statement.
- Updated asset_packer to generate only raw data and the record array.

Summarizes recent implementations including Asset Management, audio/visual fixes, and style improvements.

This commit applies a new project-wide rule that every source file must begin with a concise 3-line comment header describing its purpose.
- Updated CONTRIBUTING.md with the new rule.
- Applied headers to all .cc and .h files in src/ and tools/.
- Fixed various minor compilation errors and missing includes discovered during the header update process.

This commit makes the asset packer fully functional and adds an end-to-end test suite.
- Updated asset_packer.cc to read file contents and embed them as hex arrays.
- Added actual asset files (null.bin, test_asset.txt) for testing.
- Implemented src/tests/test_assets.cc to verify data integrity at runtime.
- Refactored CMakeLists.txt to handle generated file dependencies correctly.

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).

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.
