+下面展示了使用 Audio 组件记录数据的示例，代码文件请见[Audio组件](https://github.com/PaddlePaddle/VisualDL/blob/develop/demo/components/audio_test.py)
```python
from visualdl import LogWriter

-import wave

-def read_audio_data(audio_path):

- CHUNK = 4096
- f = wave.open(audio_path, "rb")
- wavdata = []
- chunk = f.readframes(CHUNK)
- while chunk:
- data = np.frombuffer(chunk, dtype='uint8')
- wavdata.extend(data)
- chunk = f.readframes(CHUNK)
- # 8k sample rate, 16bit frame, 1 channel
- shape = [8000, 2, 1]
- return shape, wavdata

- audio_shape, audio_data = read_audio_data("./testing.wav")
