Permission error in Python, when working with audiosegment in Windows 10


I wrote a short text to play the audio file. But when running, the program gives error permission. I noticed that every time I run the program, the name of the file that has the permission error is different This file is in the temp path I checked this path and there was no file with that name

Program text:

from pydub import AudioSegment
from pydub.playback import play

try:
     song=AudioSegment.from_wav("myfile.wav")

except IOError:
    print("can not open file")

try:
    play(song)
except IOError:
    print("can not play file")

The output of the program was as follows:

My Project Python/my project python/play wav.py"
can not play file

When I try the program without the block Try: , the output is as follows:

Traceback (most recent call last):
  File "d:\My Project Python\my project python\play wav.py", line 7, in <module>
    play(song)
  File "C:\Users\H&M\AppData\Local\Programs\Python\Python310\lib\site-packages\pydub\playback.py", line 71, in play    _play_with_ffplay(audio_segment)
  File "C:\Users\H&M\AppData\Local\Programs\Python\Python310\lib\site-packages\pydub\playback.py", line 15, in _play_with_ffplay
    seg.export(f.name, "wav")
  File "C:\Users\H&M\AppData\Local\Programs\Python\Python310\lib\site-packages\pydub\audio_segment.py", line 867, in export
    out_f, _ = _fd_or_path_or_tempfile(out_f, 'wb+')
  File "C:\Users\H&M\AppData\Local\Programs\Python\Python310\lib\site-packages\pydub\utils.py", line 60, in _fd_or_path_or_tempfile
    fd = open(fd, mode=mode)
PermissionError: [Errno 13] Permission denied: 'C:\\Users\\H&M\\AppData\\Local\\Temp\\tmp7t2o2ta1.wav'

Solution

  • This also works:

    def _play_with_ffplay(seg):
    PLAYER = get_player_name()
    with NamedTemporaryFile("w+b", suffix=".wav") as f:
        f.close()
        seg.export(f.name, "wav")
        subprocess.call([PLAYER, "-nodisp", "-autoexit", "-hide_banner", f.name])
    

    Just close the file with the f.close() command
