OwnAudioSharp.Mobile

Cross-platform audio library for .NET mobile applications

OwnAudioSharp.Mobile is a professional-grade audio engine providing high-performance audio playback, recording, and processing for Android and iOS with zero external dependencies.

Key Features

• Native Audio Engine: Built on PortAudio and MiniAudio for high-performance, low-latency audio processing on Android and iOS
• Multi-format Support: Built-in decoders for MP3, WAV, and FLAC
• Real-time Processing: Zero-allocation design with lock-free buffers for professional-grade performance
• Advanced Audio Features:
  • Network Synchronization: Multi-device audio sync across WiFi (< 20ms accuracy)
  • Master Clock: Sample-accurate timeline synchronization for multi-track playback
  • AI-powered vocal removal (ONNX-based neural separation)
  • Audio matchering and mastering
  • Real-time chord detection
  • Built-in effects and DSP routines

Quick Start

using OwnaudioNET;
using OwnaudioNET.Features.Vocalremover;

// Initialize the audio engine
OwnaudioNet.Initialize();
OwnaudioNet.Start();

// Create the audio mixer using the underlying engine
var mixer = new AudioMixer(OwnaudioNet.Engine.UnderlyingEngine);
mixer.Start();

// Play an audio file
var music = new FileSource("music.mp3");
mixer.AddSource(music);

// Synchronized Multi-track Playback (Master Clock)
var vocals = new FileSource("vocals.wav");
var backing = new FileSource("backing.mp3");

mixer.AddSource(vocals);
mixer.AddSource(backing);

// Attach sources to the Master Clock for sample-accurate sync
vocals.AttachToClock(mixer.MasterClock);
backing.AttachToClock(mixer.MasterClock);

// Start sources individually
vocals.Play();
backing.Play();

// Network Synchronization - Multi-Device Audio
// Perfect for: Party mode, car audio sync, wireless speakers
// Server mode (main phone/tablet)
await OwnaudioNet.StartNetworkSyncServerAsync(port: 9876);

// Client mode (other devices on WiFi)
await OwnaudioNet.StartNetworkSyncClientAsync(
    serverAddress: null,  // Auto-discovery on WiFi
    allowOfflinePlayback: true);

// All devices play in perfect sync over WiFi
// Automatic reconnection if WiFi drops

// AI Vocal Removal
var options = new SimpleSeparationOptions 
{ 
    Model = InternalModel.Best, 
    OutputDirectory = "output" 
};

using var separator = new SimpleAudioSeparationService(options);
separator.Initialize();
var result = separator.Separate("song.mp3");
// result.VocalsPath and result.InstrumentalPath contain the output files

Platform Support
