Fixing aifc module error

[danielvxsp]

Wtf is happening

When clicking "choose audio file"
this error is returned:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib64/python3.13/tkinter/__init__.py", line 2068, in __call__

    import aifc
ModuleNotFoundError: No module named 'aifc'

Breakdown:

• Error occurs when choosing though the open_file_dialog command that runs when clicking the button
• Then file_path is set to the chosen file and the directory that it was chosen in is saved in the config file
• Finally process_audio_file(file_path) is called

def process_audio_file(file_path, duration=30, sample_rate=22050):
    try:
        display_metadata(file_path)
        y, sr = librosa.load(file_path)
        tempo, beat_frames = librosa.beat.beat_track(y=y, sr=sr)
        result_label.config(text=f"Tempo: {tempo:} BPM")
        detect_key(file_path)

• the issue seems to be that bla calls blabla that calls bla that uses the aifc module which is deprecated in python3.13

• Not related, y, sr = librosa.load(file_path) is called twice, once in process_audio_file which is called in open_file_dialogue and in open_file_dialog itself to sort it in the bpm ranges
  - this is a separate issue. I noticed that this process was slow before and couldn't figure out why, it may be because the file is being analyzed twice when I can use the bpm from when its detected to sort it. This is a separate issue though

• It seems as though the issue can be explained like this

  • When I call librosa it looks for the available backends, the main one being audioread
  • In /home/$USER/.local/lib/python3.13/site-packages/audioread/__init__.py the module rawread is called which itself calls aifc in line 16
  • So the point of error seems to be rawread aifc module is deprecated (and removed in Python 3.13) beetbox/audioread#144

Fixing:

• Fixing the issue requires the user to download "standard-[afic,sunau]" through pip (Im not sure if the python-xyz package is avaliable in distributions like debian and arch but for Fedora and windows it works)
• Even though I think only aifc is required for my use case both need to be installed for the program to work
• Ill need to investigate further and see if there's a different or/and better way to fix this
