MP3 exports unreadable/corrupted

[Koowah]

Steps to reproduce

from pydub import AudioSegment

def main():
    mp3_file_path = "tests/146218705.mp3"
    wav_file_path = mp3_file_path.replace("mp3", "wav")
    new_mp3_file_path = mp3_file_path.replace(".mp3", "_new.mp3")

    sound = AudioSegment.from_mp3(mp3_file_path)
    sound.export(wav_file_path, format="wav")

    sound = AudioSegment.from_wav(wav_file_path)
    sound.export(new_mp3_file_path, format="mp3")

if __name__ == "__main__":
    main()

Expected behavior

I should be able to export AudioSegments to mp3

Actual behavior

All mp3 exports are corrupted or unreadable.
There is no problem with wav exports.

Your System configuration

• Python version: 3.9.19
• Pydub version: 0.25.1
• ffmpeg or avlib?: ffmpeg
• ffmpeg/avlib version: 7.0.1

Is there an audio file you can include to help us reproduce?

Any audio should do the trick - I tried many coming from different sources.

To be noted

I installed ffmpeg using conda-forge

Installing ffmpeg build manually and adding its bins to PATH fixed the issue.

For anyone interested here's a tutorial. The gyan.dev build that the tutorial uses is suggested for windows installation on the official ffmpeg website.
