OwnAudioSharp is a cross-platform C# audio library providing professional-grade audio playback, recording, and processing. Built with pure managed code using native system audio APIs - no external dependencies required.

New Feature: VOCAL REMOVER API

Advanced AI-driven audio separation technology for separating songs into vocal and instrumental components. It uses state-of-the-art ONNX neural network models with STFT-based processing and intelligent noise reduction.

⚠️ Important Notice

Version 2.0.0 introduces major improvements!

Pre-2.0.0 versions relied on native libraries (miniaudio, portaudio, ffmpeg) and were less optimized. Starting from version 2.0.0, OwnAudioSharp operates with zero external dependencies using a fully managed audio engine.

Key changes:

• ✅ Fully managed audio engine across all platforms
• ✅ ~90% backward compatibility with previous API
• ✅ Significant performance improvements
• ⚠️ Legacy APIs marked as [Obsolete] - will be removed in future versions

Using OwnaudioSharp version 2 with older code: If you need pre-2.0.0 functionality because you wrote your code for an older version of OwnaudioSharp, replace the Ownaudio namespaces in your code with the OwnaudioLegacy namespace. for example: Ownaudio.Source ⇒ OwnaudioLegacy.Source

Migration recommendation: Use version 2.0.0 or later for all new projects. The new managed engine offers superior performance and maintainability.

✨ Key Features

• Cross-platform: Windows (WASAPI), macOS (Core Audio), Linux (PulseAudio), iOS & Android (in progress)
• Dual API layers: Core API (low-level control) and NET API (high-level features)
• Audio playback: Support for MP3, WAV, FLAC
• Real-time processing: Pitch shifting, tempo control, effects
• Audio mixing: Multi-source mixing with synchronized playback
• Professional mastering: AI-driven audio matchering and EQ analysis
• Chord detection: Automatic musical chord recognition
• Zero-allocation: Optimized performance for real-time usage

🚀 Quick Start Example

using Ownaudio.Core;
using Ownaudio.Decoders;

// Create audio engine with default settings
using var engine = AudioEngineFactory.CreateDefault();
engine.Initialize(AudioConfig.Default);
engine.Start();

// Create decoder for audio file
using var decoder = AudioDecoderFactory.Create(
    "music.mp3",
    targetSampleRate: 48000,
    targetChannels: 2
);

// Decode and play frames
while (true)
{
    var result = decoder.DecodeNextFrame();
    if (result.IsEOF) break;
    
    engine.Send(result.Frame.Samples);
}

engine.Stop();
