  • 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
