Any docs/examples on how to do the audio separation with HP5_only_main_vocal and DeEcho about retrieval-based-voice-conversion HOT 4 OPEN

from rvc.modules.uvr5.vr import AudioPreprocess

def separate():
    input_path = f"{project_dir}/sandbox/inputs/input.mp3"
    output_path = Path(f"{project_dir}/sandbox/outputs/")

    model_name = "HP5_only_main_vocal.pth"
    model_path = os.path.join(os.getenv("weight_uvr5_root"), model_name)
    agg = 10  

    pre_fun = AudioPreprocess(model_path, agg)
    result = pre_fun.process(input_path)

    wav_instrument, wav_vocals, sr, agg = result
    sf.write(f"{output_path}/instrumental.wav", wav_instrument / 32768, sr)
    sf.write(f"{output_path}/vocals.wav", wav_vocals / 32768, sr)

    uvr_module.uvr_wrapper(
        inputpath, outputpath, model_name=modelname, export_format=format
    )
    ```
    
    But not sure this actually works, as the wrapper does not accept an output_path, it returns the files.
    
    Have also tried to use the wrapper directly:
    
    ```
        uvr = UVR()
    results = uvr.uvr_wrapper(input_path, agg=10, model_name="HP3_all_vocals.pth")

    for i, result in enumerate(results):
        wav_instrument, wav_vocals, sr, agg = result
        sf.write(f"{output_path}/instrument_{i}.wav", wav_instrument / 32768, sr)
        sf.write(f"{output_path}/vocals_{i}.wav", wav_vocals / 32768, sr)
