python生成静音音频

import numpy as np import wave def generate_silence_wav(path, duration=5, sample_rate=16000): num_samples = int(duration * sample_rate) # int16 静音 silence = np.zeros(num_samples, dtype=np.int16) with wave.open(path, 'w') as wf: wf.setnchannels(1) # 单声道 wf.setsampwidth(2) # 16bit = 2 bytes wf.setframerate(sample_rate) wf.writeframes(silence.tobytes()) generate_silence_wav("silent.wav", duration=5)
