## 🚀 Quick Start
```python
from transformers import pipeline

# Load the model
classifier = pipeline(
    "audio-classification", 
    model="AIGenLab/AST-speech-and-music-classifier-82K"
)

# Classify audio
result = classifier("your_audio.wav")
print(result)
```

---

## 🔧 Advanced Usage
```python
from transformers import AutoModelForAudioClassification, AutoFeatureExtractor
import torch
import torchaudio

# Load model and feature extractor
model = AutoModelForAudioClassification.from_pretrained(
    "AIGenLab/AST-speech-and-music-classifier-82K"
)
feature_extractor = AutoFeatureExtractor.from_pretrained(
    "AIGenLab/AST-speech-and-music-classifier-82K"
)

# Load audio (16kHz required)
audio, sr = torchaudio.load("audio.wav")
if sr != 16000:
    audio = torchaudio.functional.resample(audio, sr, 16000)

# Process
inputs = feature_extractor(
    audio.squeeze().numpy(), 
    sampling_rate=16000, 
    return_tensors="pt"
)

# Predict
with torch.no_grad():
    outputs = model(**inputs)
    predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)

music_score = predictions[0][0].item()
speech_score = predictions[0][1].item()

print(f"Music: {music_score:.3f}")
print(f"Speech: {speech_score:.3f}")
```
