"SyntaxWarning: invalid escape sequence \("

Hi, on Python v3.12 it shows the error:

SyntaxWarning: invalid escape sequence '\(
SyntaxWarning: invalid escape sequence '\)

On v3.12 changed the meaning of the regular expressions, and in places where was used \. now is only ..
So "\Python\Lib\site-packages\pydub\utils.py" must be corrected from line 299:

    for token in extra_info[stream['index']]:
        m = re.match('([su]([0-9]{1,2})p?) (([0-9]{1,2}) bit)$', token)
        m2 = re.match('([su]([0-9]{1,2})p?)( (default))?$', token)
        if m:
            set_property(stream, 'sample_fmt', m.group(1))
            set_property(stream, 'bits_per_sample', int(m.group(2)))
            set_property(stream, 'bits_per_raw_sample', int(m.group(3)))
        elif m2:
            set_property(stream, 'sample_fmt', m2.group(1))
            set_property(stream, 'bits_per_sample', int(m2.group(2)))
            set_property(stream, 'bits_per_raw_sample', int(m2.group(2)))
        elif re.match('(flt)p?( (default))?$', token):
            set_property(stream, 'sample_fmt', token)
            set_property(stream, 'bits_per_sample', 32)
            set_property(stream, 'bits_per_raw_sample', 32)
        elif re.match('(dbl)p?( (default))?$', token):
            set_property(stream, 'sample_fmt', token)
            set_property(stream, 'bits_per_sample', 64)
            set_property(stream, 'bits_per_raw_sample', 64)
    return info

Cheers.

That's in a dependency. Could you file that with pydub instead? I don't have any ability to fix it here.

Done, thank you for point me that out.
