[Proposed with solutions] Fix torchaudio path compatibility issue

[larry-ziyue-yin]

Hi Encodec Team,

I am here to propose an issue with my solution.

Bug Description

The encodec command-line tool fails when trying to load audio files due to a type compatibility issue between pathlib.Path objects and torchaudio.load().

Error Message:

RuntimeError: torchaudio_sox::load_audio_file() Expected a value of type 'str' for argument '0' but instead found type 'PosixPath'.

Steps to Reproduce

1. Install encodec: pip install encodec
2. Run: encodec -b 6.0 input.wav output.wav
3. Error occurs at line 109 in encodec/__main__.py

Expected Behavior

The command should successfully compress/decompress audio files.

Actual Behavior

The command fails with a type casting error.

Environment

• Python 3.8
• torchaudio (latest)
• encodec (latest)

Proposed Solution

Convert Path object to string before passing to torchaudio.load():

Change from:

wav, sr = torchaudio.load(args.input)

To:

wav, sr = torchaudio.load(str(args.input))

I hope this helps, and please feel free to discuss further! :)

Best,
Ziyue
