### Description

---

**Audio** **Decode** converts the encoded audio back to uncompressed audio frames. In most cases, audio decoding is the first step of an audio processing pipeline.



### Interface

---

def audio_decode.${op_name}(**kwargs):

def ${op_name}.__call__(audio)

"""

An audio decode operator takes an audio file path as input. It decodes the audio back to audio frames.

**Args:**

**audio** (str):

Audio file path.

**Return** (iterable):

An iterator over audio frames with type `towhee.types.AudioFrame`.

"""

### Code Example



Using the default audio_decode implementation and writing the pipeline in the simplified way

```Python
import towhee.DataCollection as dc



dc.glob(./music.flac)

  .audio_decode()

  .show()
```



Using the ffmpeg based implementations of audio_decode to write a same pipeline

```Python
import towhee.DataCollection as dc



dc.glob['path'](./music.flac)

  .audio_decode.ffmpeg['path', 'frames']()

  .select('frames')

  .show()
```
