Sure, you can first list all the files then select the audio files.

Here is how to list all the files (the runtime will depend on how many files you have):

```python
from os import listdir
from os.path import isfile, join
onlyfiles = [f for f in listdir(mypath) if isfile(join(mypath, f))]
```

Now you can filter `onlyfiles` to only keep audio files, to do that tell me which extensions you expect (such as ".mp3", ".wav", etc.)
