When I use mutagen I get the following error:

Traceback (most recent call last):
  File "C:UserswiznePycharmProjects3.9RedditCoquiTest.py", line 16, in <module>

    raise HeaderNotFoundError("can't sync to MPEG frame")
mutagen.mp3.HeaderNotFoundError: can't sync to MPEG frame

This is what my code looks like:

import os
from mutagen.mp3 import MP3
from TTS.api import TTS


sentences = ["Nurgle","Khorne","Slaanesh","Tzeetch"]

for i, sentence in enumerate(sentences):
    model_name = "tts_models/en/ljspeech/tacotron2-DDC_ph"
    print(f"Using model: {model_name}")
    filename = os.path.join("output", f'sentence_{i + 1:03d}.mp3')
    tts = TTS(model_name=model_name, progress_bar=False).to("cpu")
    tts.tts_to_file(text=sentence, file_path=filename)

    audio = MP3(filename)
    print(audio.info.length)

For troubleshooting I tried having Mutagen read the file outside of my venv, which it reads just fine?? In the venv I am using python 3.9 and on my command line its python 3.12, I can’t determine any other difference between those tests. Any help would be greatly appreciated!!
