Installation
Below are common installation patterns for different environments. Choose the one that matches your project.
1) JavaScript/TypeScript (npm)
Install via npm for web, Electron, or React Native projects:
npm install cxmusicplayer # or yarn add cxmusicplayer Then import:
import CXMusicPlayer from 'cxmusicplayer'; const player = new CXMusicPlayer(); 2) Android (Gradle)
Add the library to your module-level Gradle file:
dependencies { implementation 'com.cxmusic:cxmusicplayer:1.2.0' } Initialize in your Application or Activity:
CXMusicPlayer.init(getApplicationContext()); CXMusicPlayer player = new CXMusicPlayer(); 3) iOS (CocoaPods / Swift Package Manager)
CocoaPods:
pod 'CXMusicPlayer', '~> 1.2' Swift Package Manager:
- Use Xcode -> File -> Add Packages… and search for the CXMusicPlayer repo.
Initialize in Swift:
import CXMusicPlayer let player = CXMusicPlayer() 4) Desktop (C/C++ Bindings)
Download prebuilt binaries or build from source. Link against the CXMusicPlayer library and include headers:
#include <cxmusicplayer.h> CXPlayer* player = cx_player_create(); Core Concepts and API Overview
CXMusicPlayer centers around a simple player object, playlist management, and a set of events for playback state. The following explains common operations and patterns.
Player lifecycle
- create/init — instantiate the player and configure global settings.
- load — prepare a track or playlist (local file, URL, or stream).
- play/pause/stop — control playback.
- seek — jump to a position in the current track.
- destroy — release resources.
Basic usage (JavaScript example)
import CXMusicPlayer from 'cxmusicplayer'; const player = new CXMusicPlayer({ volume: 0.8, prefetch: true, }); player.on('ready', () => console.log('Player ready')); player.on('play', track => console.log('Now playing', track.title)); player.on('ended', () => console.log('Track ended')); await player.load('https://example.com/track.mp3'); player.play(); Playlist management
- add(track), remove(trackId), next(), previous(), shuffle(), repeat(mode).
- Supports metadata (title, artist, album, artwork), cue points, and chapters.
Key Features
Supported formats and codecs
CXMusicPlayer supports common codecs out of the box: MP3, AAC, OGG, FLAC, WAV. Additional codecs can be added via plugins for specialized needs.
Low-latency mode
An optional low-latency mode reduces buffering and playback delay for real-time applications (games, live mixing). Use with caution on unreliable networks.
Gapless playback
Seamless transitions between tracks for albums and mixes. Works by pre-decoding and crossfading audio frames.
Crossfade and transitions
Built-in crossfade with configurable duration and curve (linear, logarithmic, exponential).
Equalizer and effects
- 5-band or 10-band equalizer presets and custom curves.
- Built-in effects: reverb, echo, pitch shift (CPU cost varies by platform).
- Effects are chainable and available via the plugin API.
Visualizers and UI components
A set of visualizer plugins (spectrum, waveform, VU meter) and ready-made UI components for common controls (play/pause, seek bar, playlist view).
DRM and encrypted streams
Support for AES-encrypted streams and token-based access. Integration points for popular DRM systems via plugins.
Integration Tips and Best Practices
1) Choose the correct build for your platform
Use prebuilt binaries for production when available; build from source only if you need custom patches or native optimizations.
2) Use streaming-friendly patterns
When streaming long audio files, enable prefetch and progressive decoding to reduce memory footprint. Use resume points to recover from network interruptions.
3) Manage threading carefully
On native platforms, run heavy audio decoding and effects on background threads. Keep UI thread interactions minimal—use events/callbacks to update UI.
4) Optimize battery and CPU
- Reduce sample rate or disable high-cost effects on mobile.
- Use hardware-accelerated codecs when available.
- Pause or reduce processing when the app is backgrounded.
5) Handle network errors gracefully
Implement retry/backoff, fallback to lower-bitrate streams, and user-facing status indicators for connectivity issues.
6) Respect user settings
Sync CXMusicPlayer volume and output selection with system settings, allow user to choose audio output device (when platform supports it).
Example: Building an Electron Music App
- npm install cxmusicplayer electron
- Create a simple player module that runs in the renderer or main process depending on your architecture.
- Use the visualizer plugin to show spectrum animations in the UI.
- Persist playlists and settings using local storage or an embedded database.
Code snippet (renderer):
import CXMusicPlayer from 'cxmusicplayer'; const player = new CXMusicPlayer({ volume: 0.7 }); player.load('local/path/song.mp3'); player.play(); player.on('timeupdate', (pos) => { // update seek bar }); Troubleshooting Common Issues
- No sound: check output device, app/system mute, and volume settings. Confirm codec support for the file.
- Crashes on load: ensure native binaries match target OS/architecture and that permissions are set for reading files.
- High CPU: disable effects or lower buffer sizes; profile to find decoding hotspots.
- Sync issues on video: use audio clock synchronization features if available in CXMusicPlayer or use platform media APIs for A/V sync.
Security and Licensing
CXMusicPlayer itself may be offered under different licenses depending on distribution (MIT, LGPL, or commercial). Verify the license for your chosen build, especially if bundling with proprietary software. For encrypted streams, ensure secure storage of decryption keys and use secure channels (HTTPS/TLS) for token exchange.
Tips for Extending CXMusicPlayer
- Write plugins for new codecs or DSP effects; follow the plugin API conventions (init, process, teardown).
- Add platform-specific integrations: media keys, system notifications, lock-screen controls.
- Contribute visualizers or UI components back to the community to accelerate adoption.
Conclusion
CXMusicPlayer aims to strike a balance between simplicity and power: easy to integrate for basic playback, yet extensible for advanced audio scenarios. Start with the official SDK for your platform, follow platform-specific performance tips, and extend via plugins for custom codecs, effects, or UI. With sensible defaults and an event-driven API, it should be straightforward to add robust audio playback to your app.
