RVC INFERPY

Note

This project is still under development..

rvc_inferpy is a Python library for performing audio inference with RVC (Retrieval-based Voice Conversion). It provides a simple command-line interface (CLI) and can be integrated into Python projects for audio processing with customizable parameters.

Installation

You can install the package using pip:

pip install rvc-inferpy

Usage

Command Line Interface (CLI)

You can interact with rvc_inferpy through the command line. To view the available options and how to use the tool, run:

rvc-cli -h

Here’s a breakdown of the full command-line options:

Example Command:

rvc-cli --model_name "model_name_here" --audio_path "path_to_audio.wav" --f0_change 0 --f0_method "crepe" --min_pitch 50 --max_pitch 800

As a Dependency in a Python Project

You can also use rvc_inferpy directly in your Python projects. Here's an example:

from rvc_inferpy import infer_audio

inferred_audio = infer_audio(
    model_name="model_name_here",       # Name or path to the RVC model
    audio_path="path_to_audio.wav",     # Path to the input audio file
    f0_change=0,                        # Change in fundamental frequency
    f0_method="crepe",                  # F0 extraction method ("crepe", "dio", etc.) 
    crepe_hop_length=128,               # Hop length for Crepe
    index_rate=1.0,                     # Index rate for model inference
    filter_radius=3,                    # Radius for smoothing filters
    rms_mix_rate=0.75,                  # Mixing rate for RMS
    protect=0.33,                       # Protect level to prevent overfitting
    split_infer=True,                   # Whether to split audio for inference
    min_silence=0.5,                    # Minimum silence duration for splitting
    silence_threshold=-40,              # Silence threshold in dB
    seek_step=10,                       # Seek step in milliseconds
    keep_silence=0.1,                   # Keep silence duration in seconds
    quefrency=0.0,                      # Cepstrum quefrency adjustment
    tumbre=1.0,                         # Timbre preservation level
    f0_autotune=False,                  # Enable or disable F0 autotuning
    
)

The infer_audio function will return the processed audio object based on the provided parameters

Tip

Ensure that you upload your models in the models/{model_name} folder.
