**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.
Using the default audio_decode implementation and writing the pipeline in the simplified way
### 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):
### Code Example
Audio file path.
---
**Return** (iterable):
```Python
import towhee
An iterator over audio frames with type `towhee.types.AudioFrame`.
towhee.glob('./music.mp3')
.audio_decode().flaten()
"""
```
### Code Example
### Factory Constructor
---
Using the default audio_decode implementation and writing the pipeline in the simplified way
Create the operator via the following factory method
```Python
import towhee.DataCollection as dc
audio_decode.ffmpeg()
### Interface
dc.glob(./music.flac)
---
.audio_decode()
"""
.show()
```
An audio decode operator takes an audio file path as input. It decodes the audio back to audio frames.
**Args:**
**audio** (str):
Using the ffmpeg based implementations of audio_decode to write a same pipeline
Audio file path.
```Python
import towhee.DataCollection as dc
**Return** (generator):
An generator over audio frames with type `towhee.types.AudioFrame`.
