🎧 AudioEngine SDK – Advanced Audio Conversion for iOS

AudioEngine SDK is a lightweight, high-performance iOS framework that brings robust audio format conversion capabilities to your app—particularly for formats that Apple does not support natively, such as OGG, OGA, and MPEG.

Built on top of powerful open-source libraries like SFBAudioEngine and SwiftOgg, this SDK makes it easy to convert, encode, and decode a wide range of audio formats for both playback and processing.

🚀 Features

• 🔄 Bidirectional Format Conversion

  • Convert .m4a, .wav ➝ .mp3, .ogg
  • Convert .ogg, .oga, .mpeg ➝ .mp3, .m4a

• ⚙️ Powered by Proven Libraries

  • 🎧 SFBAudioEngine: High-quality encoding and decoding for MP3 and other popular formats
  • 🌀 SwiftOgg: Native support for Ogg and Oga formats

• 📱 Seamless Integration

  • Optimized for use in any iOS app requiring audio format compatibility
  • Straightforward API for converting files with minimal setup

📦 Installation

Swift Package Manager (Recommended)

Add the following to your Package.swift:

.package(url: "https://github.com/Alenroyfeild/AudioEngine.git", from: "0.0.1")

Or via Xcode:

1. Go to File > Add Packages
2. Enter the repo URL: https://github.com/Alenroyfeild/AudioEngine.git
3. Choose your version and target
4. Finish integration

✅ The SDK internally uses SFBAudioEngine and SwiftOgg for codec support — no extra configuration is required.

📌 Why Use AudioEngine SDK?

❌ Native iOS Limitations:

• No built-in support for OGG, OGA, and some MPEG formats
• Cannot encode to MP3
• .m4a (default iOS format) isn’t ideal for cross-platform use

✅ AudioEngine SDK Solves This By:

• Supporting conversion of audio to widely used formats like MP3 and OGG
• Enabling your app to play, upload, or share non-native formats
• Offering a clean and modern API to handle audio format needs effortlessly

🔁 Example Conversion Scenarios

Use Case	Conversion Path
Playback Support	.ogg, .mpeg ➝ .mp3
Upload Compatibility	.m4a, .wav ➝ .mp3, .ogg
Audio Processing	Any ➝ Target format of choice

🧱 Usage

Option 1: Manual Request Initialization

let request = AudioConversionRequest(
    sourceURL: inputFileURL,
    inputFormat: .wav,
    outputFormat: .mp3,
    outputURL: outputFileURL
)

try AudioEngine.shared.convert(request)

Option 2: Using the Builder Pattern (Recommended)

let request = try AudioConversionRequestBuilder()
    .setSourceURL(inputFileURL)
    .setInputFormat(.ogg)
    .build()

try AudioEngine.shared.convert(request)

ℹ️ Note: If the input format is .ogg or .oga, the output format is automatically set to .m4a and cannot be changed.

Optional: Set Output Format and Output URL

let request = try AudioConversionRequestBuilder()
    .setSourceURL(inputFileURL)
    .setInputFormat(.wav)
    .setOutputFormat(.mp3)
    .setOutputURL(customOutputURL)
    .build()

---

⚙️ Format Handling Rules

• .ogg and .oga inputs:
  • Output format is forced to .m4a
  • Attempting to override will be ignored
• If outputURL is not set:
  • A default file will be generated in the same directory, with a _converted suffix
