-# Supertonic iOS Example App
-
-A minimal iOS demo that runs Supertonic (ONNX Runtime) on-device. The app shows:
-- Multiline text input
-- NFE (denoising steps) slider
-- Voice toggle (M/F)
-- Generate & Play buttons
-- RTF display (Elapsed / Audio seconds)
-
-All ONNX models/configs are reused from `Supertonic/assets/onnx`, and voice style JSON files from `Supertonic/assets/voice_styles`.
-
-## Prerequisites
-- macOS 13+, Xcode 15+
-- Swift 5.9+
-- iOS 15+ device (recommended)
-- Homebrew, XcodeGen
-
-Install tools (if needed):
-```bash
-brew install xcodegen
-```
-
-## Quick Start (zero-click in Xcode)
-0) Prepare assets next to the iOS target (one-time)
-```bash
-cd ios/ExampleiOSApp
-mkdir -p onnx voice_styles
-rsync -a ../../assets/onnx/ onnx/
-rsync -a ../../assets/voice_styles/ voice_styles/
-```
-
-1) Generate the Xcode project with XcodeGen
-```bash
-xcodegen generate
-open ExampleiOSApp.xcodeproj
-```
-
-2) Open in Xcode and select your iPhone as the run destination
-- Targets → ExampleiOSApp → Signing & Capabilities: Select your Team
-- iOS Deployment Target: 15.0+
-
-3) Build & Run on device
-- Type text → adjust NFE/Voice → Tap Generate → Audio plays automatically
-- An RTF line shows like: `RTF 0.30x · 3.04s / 10.11s`
-
-## What's included (generated project)
-- SwiftUI app files: `App.swift`, `ContentView.swift`, `TTSViewModel.swift`, `AudioPlayer.swift`
-- Runtime wrapper: `TTSService.swift` (includes TTS inference logic)
-- Resources (local, vendored in `ios/ExampleiOSApp/onnx` and `ios/ExampleiOSApp/voice_styles` after step 0)
-
-These references are defined in `project.yml` and added to the app bundle by XcodeGen.
-
-## App Controls
-- **Text**: Multiline `TextEditor`
-- **NFE**: Denoising steps (default 5)
-- **Voice**: M1/M2/F1/F2 voice style selector (4 pre-extracted styles)
-- **Generate**: Runs end-to-end synthesis
-- **Play/Stop**: Controls playback of the last output
-- **RTF**: Shows Elapsed / Audio seconds for quick performance intuition

-# Supertonic Web Example
-
-This example demonstrates how to use Supertonic in a web browser using ONNX Runtime Web.
-
-## 📰 Update News
-
-**2025.11.23** - Enhanced text preprocessing with comprehensive normalization, emoji removal, symbol replacement, and punctuation handling for improved synthesis quality.
-
-**2025.11.19** - Added speed control slider to adjust speech synthesis speed (default: 1.05, recommended range: 0.9-1.5).
-
-**2025.11.19** - Added automatic text chunking for long-form inference. Long texts are split into chunks and synthesized with natural pauses.
-
-## Features
-
-- 🌐 Runs entirely in the browser (no server required for inference)
-- 🚀 WebGPU support with automatic fallback to WebAssembly
-- ⚡ Pre-extracted voice styles for instant generation
-- 🎨 Modern, responsive UI
-- 🎭 Multiple voice style presets (2 Male, 2 Female)
-- 💾 Download generated audio as WAV files
-- 📊 Detailed generation statistics (audio length, generation time)
-- ⏱️ Real-time progress tracking
-
-## Requirements
-
-- Node.js (for development server)
-- Modern web browser (Chrome, Edge, Firefox, Safari)
-
-## Installation
-
-1. Install dependencies:
-
-```bash
-npm install
-```
-
-## Running the Demo
-
-Start the development server:
-
-```bash
-npm run dev
-```
-
-This will start a local development server (usually at http://localhost:3000) and open the demo in your browser.
-
-## Usage
-
-1. **Wait for Models to Load**: The app will automatically load models and the default voice style (M1)
-2. **Select Voice Style**: Choose from available voice presets
-   - **Male 1 (M1)**: Default male voice
-   - **Male 2 (M2)**: Alternative male voice
-   - **Female 1 (F1)**: Default female voice
-   - **Female 2 (F2)**: Alternative female voice
-3. **Enter Text**: Type or paste the text you want to convert to speech
-4. **Adjust Settings** (optional):
-   - **Total Steps**: More steps = better quality but slower (default: 5)
-5. **Generate Speech**: Click the "Generate Speech" button
-6. **View Results**: 
-   - See the full input text
-   - View audio length and generation time statistics
-   - Play the generated audio in the browser
-   - Download as WAV file
-
-## Technical Details
-
-### Browser Compatibility
-
-This demo uses:
-- **ONNX Runtime Web**: For running models in the browser
-- **Web Audio API**: For playing generated audio
-- **Vite**: For development and bundling
-
-## Notes
-
-- The ONNX models must be accessible at `assets/onnx/` relative to the web root
-- Voice style JSON files must be accessible at `assets/voice_styles/` relative to the web root
-- Pre-extracted voice styles enable instant generation without audio processing
-- Four voice style presets are provided (M1, M2, F1, F2)
-
-## Troubleshooting
-
-### Models not loading
-- Check browser console for errors
-- Ensure `assets/onnx/` path is correct and models are accessible
-- Check CORS settings if serving from a different domain
-
-### WebGPU not available
-- WebGPU is only available in recent Chrome/Edge browsers (version 113+)
-- The app will automatically fall back to WebAssembly if WebGPU is not available
-- Check the backend badge to see which execution provider is being used
-
-### Out of memory errors
-- Try shorter text inputs
-- Reduce denoising steps
-- Use a browser with more available memory
-- Close other tabs to free up memory
-
-### Audio quality issues
-- Try different voice style presets
-- Increase denoising steps for better quality
-
-### Slow generation
-- If using WebAssembly, try a browser that supports WebGPU
-- Ensure no other heavy processes are running
-- Consider using fewer denoising steps for faster (but lower quality) results
