如何使用librosa将女性声音转换为男性声音？

import librosa
import numpy as np
from scipy.io import wavfile

filename = 'female_voice.wav'
y, sr = librosa.load(filename, sr=None)

y_pitch, sr_pitch = librosa.load(filename, sr=None, duration=3)
pitch = librosa.feature.rmse(y=y_pitch)

target_pitch = 100  # 目标音高，男性声音较低
pitch_adjusted = np.interp(pitch, (np.min(pitch), np.max(pitch)), (target_pitch, 1))

y_pitch_adjusted = librosa.effects.pitch_shift(y, sr, n_steps=np.mean(pitch_adjusted-pitch))

output_filename = 'male_voice.wav'
wavfile.write(output_filename, sr, y_pitch_adjusted)
