## Installation

1. Install required packages:
```bash
pip install -r requirements.txt
```

2. Download the dataset from the source link.

## Usage

### Loading the Dataset

```python
from load_data import load_environmental_sounds

# Load training data
train_data, train_labels = load_environmental_sounds('train')

# Load test data
test_data, test_labels = load_environmental_sounds('test')
```

### Analyzing Audio Files

```python
from analyze import analyze_audio_file

# Analyze a single audio file
features = analyze_audio_file('path/to/audio.wav')
print(features)
```

### Training a Model

```python
from train_model import train_classifier

# Train a classifier on the dataset
model = train_classifier(train_data, train_labels)
```

## Advanced Usage Examples

### Audio Augmentation
```python
from augment_audio import AudioAugmenter

augmenter = AudioAugmenter()
augmented_audio = augmenter.augment(audio)
```

### Deep Learning Models
```python
from deep_learning_models import AudioCNN, prepare_features_for_dl

# Prepare features
X_train = prepare_features_for_dl(train_data, feature_type='mel')
X_train = X_train[..., np.newaxis] # Add channel dimension

# Train CNN
model = AudioCNN(input_shape=(X_train.shape[1], X_train.shape[2], 1), num_classes=10)
model.train(X_train, y_train, X_val, y_val, epochs=50)
```

### Audio Similarity Search
```python
from audio_similarity import AudioSimilaritySearch

search = AudioSimilaritySearch()
search.add_audio(audio1, 'path1.wav')
search.build_index()
results = search.search(query_audio, top_k=5)
```

### Real-time Classification
```python
from realtime_classification import RealTimeClassifier
from train_model import load_model

model, scaler, label_encoder = load_model()
classifier = RealTimeClassifier(model, scaler, label_encoder)
classifier.start(callback=lambda pred, conf: print(f"{pred}: {conf:.2f}"))
```

### Model Interpretability
```python
from model_interpretability import ModelInterpreter

interpreter = ModelInterpreter(model, scaler, label_encoder)
interpreter.plot_feature_importance(X, y)
explanation = interpreter.explain_prediction(audio)
```

### Audio Quality Assessment
```python
from audio_quality import AudioQualityAssessor

assessor = AudioQualityAssessor()
is_valid, assessment = assessor.validate_audio_file('audio.wav')
print(f"Quality score: {assessment['quality_score']}")
```

### Batch Processing
```python
from batch_processing import BatchProcessor

processor = BatchProcessor()
features = processor.extract_features_batch(file_paths)
results = processor.classify_batch(file_paths, model, scaler, label_encoder)
```

### Web API
```bash
# Start API server
python api_server.py

# Make prediction
curl -X POST http://localhost:5000/predict \
-F "audio=@test.wav"
```
