Introduction

SoundFlow is a robust and versatile .NET audio engine designed for seamless cross-platform audio processing. It provides a comprehensive set of features for audio playback, recording, processing, analysis, and visualization, all within a well-structured and extensible framework.

Key Features:

• Cross-Platform by Design: Runs seamlessly on Windows, macOS, Linux, Android, and iOS or any other .NET compatible platform.
• Modular Component Architecture: Build custom audio pipelines by connecting sources, modifiers, mixers, and analyzers.
• Extensibility: Easily add custom audio components, effects, and visualizers to tailor the engine to your specific needs.
• High Performance: Optimized for real-time audio processing with SIMD support and efficient memory management.
• Playback: Play audio from various sources, including files, streams, and in-memory assets.
• Recording: Capture audio input and save it to different encoding formats.
• Mixing: Combine multiple audio streams with precise control over volume and panning.
• Effects: Apply a wide range of audio effects, including reverb, chorus, delay, equalization, and more.
• Analysis: Extract valuable information from audio data, such as RMS level, peak level, frequency spectrum, and voice activity.
• Visualization: Create engaging visual representations of audio waveforms, spectrums, and level meters.
• Surround Sound: Supports advanced surround sound configurations with customizable speaker positions, delays, and panning methods.
• HLS Streaming Support: Integrate internet radio and online audio via HTTP Live Streaming.
• Backend Agnostic: Supports the MiniAudio backend out of the box, with the ability to add others.

Getting Started

Installation

NuGet Package Manager:

Install-Package SoundFlow

.NET CLI:

dotnet add package SoundFlow

Basic Usage Example

This example demonstrates how to play an audio file using SoundFlow:

using SoundFlow.Abstracts;
using SoundFlow.Backends.MiniAudio;
using SoundFlow.Components;
using SoundFlow.Providers;
using SoundFlow.Enums;

// Initialize the audio engine with the MiniAudio backend
using var audioEngine = new MiniAudioEngine(44100, Capability.Playback);

// Create a SoundPlayer and load an audio file
var player = new SoundPlayer(new StreamDataProvider(File.OpenRead("path/to/your/audiofile.wav")));

// Add the player to the master mixer
Mixer.Master.AddComponent(player);

// Start playback
player.Play();

// Keep the console application running until playback finishes
Console.WriteLine("Playing audio... Press any key to stop.");
Console.ReadKey();

// Stop playback and remove the player from the mixer
player.Stop();
Mixer.Master.RemoveComponent(player);

Core Concepts

SoundFlow is built upon a few key concepts:

• Audio Engine (AudioEngine): The central component that manages audio device initialization, data processing, and the audio graph.
• Sound Components (SoundComponent): Modular units that process or generate audio, forming a directed graph through input and output connections.
• Mixer (Mixer): Combines multiple audio streams into a single output.
• Sound Modifiers (SoundModifier): Apply audio effects like reverb, chorus, delay, and equalization.
• Audio Playback & Recording: Components for playing and capturing audio, including surround sound support.
• Audio Providers: Standardized way to read audio data from various sources (files, streams, memory).
• Audio Analysis & Visualization: Tools for extracting information from audio and creating visual representations.

For detailed information on these concepts, please refer to the SoundFlow Documentation.

API Reference

Comprehensive API documentation will be available on the SoundFlow Documentation.

Tutorials and Examples

The Documentation provides a wide range of tutorials and examples to help you get started:

• Playback: Playing audio files and streams, controlling playback.
• Recording: Recording audio, using voice activity detection.
• Effects: Applying various audio effects.
• Analysis: Getting RMS level, analyzing frequency spectrum.
• Visualization: Creating level meters, waveform displays, and spectrum analyzers.

(Note: You can also find example code in the Samples folder of the repository.)

Support This Project

SoundFlow is an open-source project driven by passion and community needs. Maintaining and developing a project of this scale, especially with thorough audio testing, requires significant time and resources.

Currently, development and testing are primarily done using built-in computer speakers. Your support will directly help improve the quality of SoundFlow by enabling the purchase of dedicated headphones and audio equipment for more accurate and comprehensive testing across different audio setups.

Beyond equipment, your contributions, no matter the size, help to:

• Dedicate more time to development: Allowing for faster feature implementation, bug fixes, and improvements.
• Enhance project quality: Enabling better testing, documentation, and overall project stability (including better audio testing with proper equipment!).
• Sustain long-term maintenance: Ensuring SoundFlow remains actively maintained and relevant for the community.

You can directly support SoundFlow and help me get essential headphones through:

• Ko-fi: For simple one-time donations or flexible recurring support.
