#4490 Ref Audio Missing: C:/pyvideotrans/f5-tts/nicdd.wav

The error indicates that the reference audio file nicdd.wav is missing from the required directory C:/pyvideotrans/f5-tts/.

Root Cause:
You are using a TTS channel (F5-TTS, Index-TTS, VoxCPM, Spark-TTS, or Dia-TTS) that requires a reference audio file for voice cloning. This file must be placed in the f5-tts folder inside the software’s root directory (C:/pyvideotrans/f5-tts/), and the file name must be entered exactly in the TTS settings (including the extension).

Solution:

1. Confirm that nicdd.wav exists inside C:/pyvideotrans/f5-tts/.
2. Verify the file name spelling and extension (case-sensitive).
3. Ensure the audio file is a valid WAV file, with duration between 3–10 seconds for best results.
4. In the software menu, go to Menu → TTS Settings → F5-TTS (or the corresponding section), and fill in the reference audio name as nicdd.wav (without any path).
5. If the file is located elsewhere, move or copy it to the C:/pyvideotrans/f5-tts/ folder.

If the issue persists, check whether the path contains special characters or spaces (recommended: only English letters and numbers).
