Development Blog: Adding Audio Merge Functionality and Optimizing Backend Logic
Date: 2025-03-18
Author: Wesley Xu
Overview
This development cycle focused on adding an audio merge function, refactoring audio processing logic, and optimizing model path settings for better cross-platform compatibility. These updates aim to enhance the backend’s functionality, improve maintainability, and streamline resource management.
1. Audio Merge Functionality
Description:
We introduced a new audio merge function that allows users to upload multiple audio files and merge them into a single track. This feature is particularly useful for creating seamless audio compositions.
Key Features:
- Added support for file uploads and merging multiple audio tracks.
- Implemented logic to handle different audio formats and ensure consistent output quality.
- Updated
.gitignoreto exclude audio files from being committed to the repository.
Impact: This feature expands the backend’s capabilities, enabling more advanced audio processing workflows while maintaining repository cleanliness.
2. Refactored Audio Processing Logic
Description:
We refactored the audio processing logic to improve file management and resource handling. Output files are now saved to specific subdirectories, and unused static files are automatically deleted.
Key Changes:
- Output files are saved to organized subdirectories based on their type and purpose.
- Updated returned file URL paths to reflect the new directory structure.
- Implemented automatic cleanup of static files that are no longer in use.
Impact: These changes improve the maintainability of the backend by organizing output files and reducing clutter in the static file directory.
3. Optimized Model Path Settings
Description:
We optimized the model path settings to unify the use of base directories and enhance cross-platform compatibility. This ensures that the backend works seamlessly across different environments.
Key Features:
- Unified the use of base directories for model path resolution.
- Enhanced cross-platform compatibility by standardizing path handling logic.
- Improved error handling for missing or invalid model paths.
Impact: These updates reduce errors caused by inconsistent directory structures and improve the backend’s reliability in diverse deployment environments.
4. Testing
Description:
The changes were tested with various audio inputs and deployment environments to ensure proper functionality.
Key Results:
- Audio merge function successfully combines multiple tracks into a single output file.
- Refactored audio processing logic correctly saves and cleans up files as expected.
- Model path settings work seamlessly across Windows, macOS, and Linux environments.
