+# SVC Voice Changer
+
+- [so-vits-svc-fork @ GitHub](https://github.com/voicepaw/so-vits-svc-fork)
+- [pre-trained models @ HuggingFace](https://huggingface.co/models?search=so-vits-svc)
+
+so-vits-svc is one of simpler voice changers to set up on Linux. It can run on CPU as well as NVidia and AMD GPUs.
+
+This is an exert of the original README.md of the GitHub repository, intended for people who are as bad with Python as I am.
+
+# Setup
+
+Disclaimer: There's probably a better way. I'm not good at Python. Or machine learning.
+
+### Prerequisites:
+
+Install the following packages using your distro's package manager:
+- Python 3.10
+- Pip for Python 3.10
+- Virtualenv for Python 3.10
+
+Please use 3.10 exactly, not newer or older.
+
+### Create virtualenv:
+
+In this example, we will create the virtualenv inside `~/.var/venv/`. Feel free to change the location, any folder will work.
+
+Create virtualenv:
+```bash
+mkdir -p ~/.var/venv/svc/
+cd ~/.var/venv/svc/
+python3.10 -m venv .
+```
+
+Activate virtualenv
+- On fish: `. bin/activate.fish`
+- On csh: `. bin/activate.csh`
+- On bash/zsh: `. bin/activate`
+
+At this point, if you call python or pip, you will be running that command inside the virtualenv.
+
+You can activate the virtualenv again by `cd ~/.var/venv/svc/` followed by the activate command for your shell.
+
+To exit the virtualenv, run `deactivate`.
+
+### Install SVC
+
+Do these while you have the virtualenv activated.
+
+Install required tools: 
+- `python -m pip install -U pip setuptools wheel`
+
+PyTorch with CUDA support for NVIDIA GPUs:
+- Please install CUDA 11.8 using your system package manager. Newer versions may not work.
+- `pip install -U torch torchaudio --index-url https://download.pytorch.org/whl/cu118`
+
+PyTorch with ROCm support for AMD GPUs:
+- Please install ROCm 5.7.1 via your system package manager. Newer versions may not work.
+- `pip install -U torch torchaudio --index-url https://download.pytorch.org/whl/rocm5.7`
+
+PyTorch for CPU only (you can also choose CPU mode with the options above):
+- `pip install -U torch torchaudio --index-url https://download.pytorch.org/whl/cpu`
+
+Finally, install SVC:
+- `pip install -U so-vits-svc-fork`
+
+### Launch the GUI
+
+You can start the graphical UI by running `svcg` inside the virtualenv.
+
+Example start script for bash:
+```bash
+#!/usr/bin/env bash
+. ~/.var/venv/svc/bin/activate
+svcg
+```
+
+### Models
+
+Grab a model from HuggingFace (link on top of page). Models that work with this setup are the ones tagged with `
+so-vits-svc-4.0` or `so-vits-svc-4.1`.
+
+You will need 2 files for SVC to work:
+- `G_0000.pth` where 0000 is some number. Usually a higher number means better, but only if you're comparing files within the same repository.
+- `config.json` tells SVC how to use the pth file.
+
+With SVC running, plop the `G_0000.pth` into `Model Path` on the top left, and `config.json` into `Config Path`.
+
+### Starting the Voice Changer
+
+Default settings usually work OK. What you want to change is `Pitch`. This will be different depending on how high your own voice is compared to the model's voice. You will need different `Pitch` setting for different models.
+
+Check `Use GPU` on the bottom center if you want to torture your GPU with your voice. It better not complain for how expensive it was.
+
+Click `(Re)Start Voice Changer` to do just that. You also need to click this after changing any settings.
+
+### PipeWire Setup
+
+This is for ALVR-only right now. TODO the rest.
+
+Use `qpwgraph` or `helvum` to:
+1. Disconnect `vrserver` from `ALVR-MIC-Sink`.
+2. Pipe the output of `vrserver` to the input of `Python3.10`.
+3. Pipe the output of `Python3.10` to the input of `ALVR-MIC-Sink`.
