Welcome to the backend of the Rust-based Audio Player project! This repository provides the core logic and audio processing for a custom web-based audio player. https://github.com/BryanHankins/AudioPlayerFrontend/ This backend is written in Rust and compiled to WebAssembly (WASM) to enable high-performance audio playback directly in the browser. It handles decoding and playback of audio files, interfacing seamlessly with a JavaScript frontend.

Currently Supported Audio Formats: .wav, .ogg, .flac

Limitations: .mp3 files are not supported due to WebAssembly limitations with the Rodio library. 🛠️ Technologies Used

Technology Purpose Rust Backend development and audio logic WebAssembly Run Rust in the browser for better performance Rodio Rust audio playback library wasm-bindgen Create JS bindings for WASM modules JavaScript/TypeScript Connect frontend and backend

2. Build Instructions bash Copy Edit

Clone the repository

git clone https://github.com/BryanHankins/AudioPlayerBackend.git cd AudioPlayerBackend

Build the Rust project to WebAssembly

wasm-pack build --target web

Install any necessary frontend dependencies

npm install

⚠️ Known Issues MP3 Playback: Due to codec restrictions in rodio with WebAssembly, MP3 decoding is not supported. (WAV, OGG, and FLAC formats work properly.)

Future Improvements:

Add MP3 support via a lightweight decoder (e.g., minimp3 crate).

Add frontend fallback when unsupported files are uploaded.
