is a compressed archive containing pretrained base models used primarily for Retrieval-based Voice Conversion (RVC) , a popular AI technology for creating high-quality voice clones. What is in the file?
This archive typically contains the files that allow the AI to understand human speech before you even begin training it on a specific person's voice. Without these base models, you would need massive amounts of data and weeks of computing time to train a voice from scratch. prev-train.7z
It usually includes f0G40k.pth and f0D40k.pth (or similar versions for different sample rates like 32k or 48k). G (Generator): Responsible for generating the audio. is a compressed archive containing pretrained base models
Most users look for this file when setting up RVC v2 . The "v2" models are generally more stable and produce clearer audio than the original versions. How to Use It Without these base models, you would need massive
Helps the AI "critique" the audio to make it sound more realistic during training.
When you open your training interface, you will select these as your "Pretrained G" and "Pretrained D" paths. This gives your specific voice training a head start. Where to Find It
Always ensure you are downloading from a reputable source like Hugging Face or the official GitHub repository of the tool you are using to avoid malware. If you'd like, I can help you with: Finding the exact download link for a specific RVC version. Troubleshooting "File Not Found" errors during training.
