Analyzing folders on Windows in Python

[Dylan Osterhaus]

Hello,

I am trying to analyze the following folder C:\Users\dylano\Desktop\Sound using the following code form github. This folder contains 10, 1-hour long .wav files.

"""""""""""""""""""""""""""""""""""""""""""""""""""

import birdvoxdetect as bvd

df = bvd.process_file('C:/Users/dylano/Desktop/Sound')

"""""""""""""""""""""""""""""""""""""""""""""""""""

and receive the following error

"""""""""""""""""""""""""""""""""""""""""""""""""""""

>>> df = bvd.process_file('C:/Users/dylano/Desktop/Sound')
Traceback (most recent call last):
  File "C:\Users\dylano\AppData\Local\Programs\Python\Python37\lib\site-packages\birdvoxdetect\core.py", line 121, in process_file
    sound_file = sf.SoundFile(filepath)
  File "C:\Users\dylano\AppData\Local\Programs\Python\Python37\lib\site-packages\soundfile.py", line 740, in __init__
    self._file = self._open(file, mode_int, closefd)
  File "C:\Users\dylano\AppData\Local\Programs\Python\Python37\lib\site-packages\soundfile.py", line 1265, in _open
    "Error opening {0!r}: ".format(self.name))
  File "C:\Users\dylano\AppData\Local\Programs\Python\Python37\lib\site-packages\soundfile.py", line 1455, in _error_check
    raise RuntimeError(prefix + _ffi.string(err_str).decode('utf-8', 'replace'))
RuntimeError: Error opening 'C:/Users/dylano/Desktop/Sound': System error.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\dylano\AppData\Local\Programs\Python\Python37\lib\site-packages\birdvoxdetect\core.py", line 123, in process_file
    raise BirdVoxDetectError("Could not open file: {}".format(filepath))
birdvoxdetect.birdvoxdetect_exceptions.BirdVoxDetectError: Could not open file: C:/Users/dylano/Desktop/Sound

"""""""""""""""""""""""""""""""""""""""""""""""""""

What is the correct code that I need to run in order to analyze this folder? Any help would be appreciated!

Thank you,

Dylan Osterhaus

Hello Dylan,

Looking from your traceback, it seems like PySoundFile cannot open your audio data.

This may either be a problem in the audio encoding of the data (likely) or a problem with your PySoundFile installation (less likely).

I don't think this is specifically a BirdVoxDetect problem, but i might be wrong.

I hope this helps!

Sincerely,

Vincent.

Vincent,

When I analyze one of the files within the folder individually (using the code below), everything works as it should. Would this eliminate an audio encoding issue?

df = bvd.process_file('C:/Users/dylano/Desktop/Sound/WS1_20210901_045556.wav')

Thank you,

Dylan

Ah, i hadn't seen you were trying to analyze a folder, not a specific file.

process_file can only take paths from files, not folders, at input (as the name implies)

To analyze a folder, i recommend you make your own for loop. Something like:

data_dir = 'C:/Users/dylano/Desktop/Sound'

dfs = {}

for name in os.listdir(data_dir):
    df[name] = bvd.process_file(data_dir + "/" + name)

Or else use the command-line :)

birdvoxdetect path/to/folder

I hope this helps!

Vincent.

Vincent,

I tried the command line option and received a syntax error

""""""""""""""""

>>> birdvoxdetect C:\Users\dylano\Desktop\Sound
  File "<stdin>", line 1
    birdvoxdetect C:\Users\dylano\Desktop\Sound
                              ^
SyntaxError: invalid syntax
"""""""""""""""""

I am sure this is probably an easy fix but I am not at all familiar with Python. I appreciate the help!
