此步骤我们将定义一段函数,通过剪切或重复音频的方式来调整音频的长度。 defchange_audio_length(wave_file,target_length):# 获取音频参数params=wave_file.getparams()framerate=params.framerate# 采样率frames_to_read=int(framerate*target_length)# 计算需要的帧数audio_data=wave_file.readframes(frames_to_re...

返回的迭代器包含的数据块数=(fps*剪辑的时长)/chunksize+1,这个方法可以在需要对音频剪辑进行变换处理时使用。 五、to_soundarray方法 to_soundarray方法将音频片段转换为一个可以使用pygame播放或者使用wav格式保存的数组。 调用语法: to_soundarray(self, tt=None, fps=None, quantize=False, nbytes=2, buffer...
