好的,以下是使用librosa提取音频文件特征的代码:
```python
import librosa
# 读取音频文件
audio_file = 'path/to/audio/file.wav'
y, sr = librosa.load(audio_file)
# 提取音频特征
chroma_stft = librosa.feature.chroma_stft(y=y, sr=sr)
mfcc = librosa.feature.mfcc(y=y, sr=sr)
spectral_centroid = librosa.feature.spectral_centroid(y=y, sr=sr)
spectral_bandwidth = librosa.feature.spectral_bandwidth(y=y, sr=sr)
spectral_contrast = librosa.feature.spectral_contrast(y=y, sr=sr)
spectral_rolloff = librosa.feature.spectral_rolloff(y=y, sr=sr)
# 打印特征
print('Chroma STFT:', chroma_stft)
print('MFCC:', mfcc)
print('Spectral Centroid:', spectral_centroid)
print('Spectral Bandwidth:', spectral_bandwidth)
print('Spectral Contrast:', spectral_contrast)
print('Spectral Rolloff:', spectral_rolloff)
```
希望这个代码能够帮到你!
