Read time: 6 mins
Metamorph V1.1 introduces third-party RVC voice model imports via the Import Model button in the plugin’s model browser. Voice-Swap’s browser-based training tool turns 10 to 40 minutes of clean, isolated vocals into a downloadable RVC model that loads into Metamorph natively — no cloud notebooks or command-line setup required. Pre-made community models are also available on Hugging Face and Voice-Models.com.
Voice-Swap has released a training tool that turns your own vocals into a downloadable RVC voice model that is 100 percent compatible with Metamorph. What used to mean wrestling with cloud notebooks and command-line setup is now a short upload-and-create workflow you run in a browser — and that is the part of the process this guide focuses on.
What Are RVC Models?
RVC (Retrieval-based Voice Conversion) is an open-source technology that transforms one voice into another. Unlike older voice conversion methods that required hours of training data, RVC can create convincing voice models from just 5-10 minutes of clean audio. The technology has become increasingly accessible, with free tools available for training your own models on consumer hardware.
Where Can You Find Pre-Made RVC Models for Metamorph?
The RVC community has created thousands of voice models that you can download and import directly into Metamorph. Here are the best places to explore:
Hugging Face offers a growing collection of RVC models from independent creators.
Voice-Models.com aggregates over 100,000 unique voice models in a searchable database.
When downloading models, you'll typically receive a .pth file (the model itself)-- this is the type of model that can be imported into Metamorph.
How Do You Create a Custom RVC Voice Model with Voice-Swap?
Voice-Swap’s browser-based training tool turns 10 to 40 minutes of clean, isolated vocals into a downloadable RVC model that imports directly into Metamorph — no cloud notebooks or command-line setup required. Because the tool is purpose-built for Metamorph, there is no format conversion or troubleshooting between the two: the model you download is the model Metamorph loads.
1. Prepare your audio
You will want 20 to 40 minutes of clean, isolated vocals with no instrumental backing, because vocals-only material gives the model the clearest read on your voice. Remove any background noise and music with Vocal Prep first, then save your files as WAV, MP3, or M4A so they are ready to upload.
2. Name your model
Open Voice-Swap’s Create your own voice for AutoTune Metamorph page and give the model a clear name, which keeps it easy to find in your library once it is built.
3. Upload your vocals
Drag your files into the uploader, where the tool tracks your total runtime and confirms when you have enough audio to proceed. You can add up to ten files, and a readiness checklist verifies that your model name is added, that you have 20 to 40 minutes of audio, and that the material is vocals only with no music before you move on.
4. Create and download
An optional advanced settings panel lets you fine-tune the training, and creating the model then uses 40 credits and takes roughly three hours to complete. When it finishes, you download the ready-to-use model from the AutoTune Metamorph Models page, where your models and data always stay private and fully under your ownership.
Because the tool is purpose-built for Metamorph, there is no format conversion or troubleshooting between the two. The model you download is the model Metamorph loads, which is what makes Voice-Swap the most direct path to a custom voice inside the plugin.
How Do You Import an RVC Voice Model into Metamorph?
Importing an RVC model into Metamorph takes seconds: open the model browser, click Import Model, and point it at your .pth file. Metamorph handles the rest and lets you add custom names and descriptions to keep your library organized.
Imported voices run alongside Metamorph’s professionally licensed models with the same local processing, privacy protection, and unlimited usage — a model you trained this afternoon behaves exactly like one that shipped with the plugin. From there, turn on Range Matching and audition the transformed vocal in real time until it sits the way you want.
What Should You Know About Using RVC Voice Models Responsibly?
While RVC technology opens exciting creative possibilities, we encourage thoughtful use. Ensure you have appropriate rights to any source audio you use for training, and consider the ethical implications of the voices you create. Metamorph's built-in voice collection provides ethically sourced options that respect artist rights—a standard worth maintaining as you expand your library.

Frequently Asked Questions
What is an RVC voice model?
RVC stands for Retrieval-based Voice Conversion, an open-source technology that transforms one voice into another.

Is Voice-Swap compatible with AutoTune Metamorph?
Yes, Voice-Swap's training tool is 100 percent compatible with Metamorph. It outputs a standard RVC model built specifically for the plugin, so there is no format conversion or troubleshooting between the two, and the model you download is the exact model Metamorph loads.
How much audio do you need to create a voice model with Voice-Swap?
You will want 20 to 40 minutes of clean, isolated vocals with no instrumental backing, since vocals-only material gives the model the clearest read on the voice. You can upload up to ten files, and Voice-Swap runs a readiness checklist that confirms your model name, total runtime, and audio type before it begins training.
How do you import an RVC voice model into Metamorph?
Once your model has downloaded, open the model browser in Metamorph, use the Import Model button, and point it at your file. Metamorph handles the rest and lets you add custom names and descriptions, and your imported voice then runs alongside the professionally licensed models with the same local processing, privacy protection, and unlimited usage.
Where can you find pre-made RVC voice models for Metamorph?
