OwnAudioSharp 3.1.7

OwnAudioSharp

Cross-platform audio library for .NET desktop applications

OwnAudioSharp is a professional-grade audio engine providing high-performance audio playback, recording, and processing for Windows, Linux, and macOS with zero external dependencies.

Key Features

• Native Audio Engine: Built on PortAudio and MiniAudio for professional-grade, low-latency audio processing across all platforms
• Multi-format Support: Built-in decoders for MP3, WAV, and FLAC. If FFmpeg 8+ is installed on the system, it is used automatically as the primary decoder, adding support for AAC, OGG, Opus, WMA, AIFF, and virtually any other format — no code changes required.
• Real-time Processing: Zero-allocation design with lock-free buffers for professional-grade performance
• Advanced Audio Features:
  • Network Synchronization: Multi-device audio sync across local network (< 5ms accuracy on LAN)
  • Master Clock: Sample-accurate timeline synchronization for multi-track playback
  • SmartMaster Effect: Intelligent audio mastering with auto-calibration
  • 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
// Server mode (control device)
await OwnaudioNet.StartNetworkSyncServerAsync(port: 9876);

// Client mode (follower devices)
await OwnaudioNet.StartNetworkSyncClientAsync(
    serverAddress: "192.168.1.100",  // Or null for auto-discovery
    allowOfflinePlayback: true);

// All clients automatically follow server commands
// Perfect for multi-room audio, DJ setups, installations

// 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

FFmpeg Integration (Optional)

OwnAudioSharp automatically detects FFmpeg dynamic libraries on startup. This is not part of the public API — it happens transparently in the decoder layer.

Decoder priority: FFmpeg → MiniAudio (native) → built-in managed decoder

using Ownaudio.Core;

// Optional: set a custom path before first use (default: empty = system paths)
FFmpegConfig.CustomLibraryPath = @"C:\ffmpeg\bin"; // Windows example

// Check whether FFmpeg was detected successfully
if (FFmpegConfig.IsAvailable)
    Console.WriteLine("FFmpeg decoder active — extended format support enabled.");
else
    Console.WriteLine("FFmpeg not found — using built-in decoders (MP3/WAV/FLAC).");

// No API changes needed — AudioDecoderFactory selects the best decoder automatically
var decoder = AudioDecoderFactory.Create("audio.aac", targetSampleRate: 48000, targetChannels: 2);

Installation per platform:

• Windows: Place avcodec-62.dll, avformat-62.dll, avutil-60.dll, swresample-6.dll next to the executable, or anywhere on PATH.
• macOS: brew install ffmpeg
• Linux: sudo apt install libavcodec-dev libavformat-dev (or equivalent)

Platform Support

• Windows: Windows 10/11 (x64, ARM64)
• Linux: Ubuntu, Debian, Fedora, etc. (x64, ARM64)
• macOS: macOS 10.13+ (x64, ARM64)

Architecture

OwnAudioSharp uses a two-layer architecture:

1. Engine Layer: Low-level platform-specific audio processing with real-time thread management
2. API Layer: High-level thread-safe wrappers with lock-free ring buffers to prevent UI blocking
