要使用Python和FFmpeg进行音频文件的变速操作,首先需要安装FFmpeg插件。可以使用pip命令来安装FFmpeg,命令为:pip install ffmpeg。然后,在Python代码中导入FFmpeg库进行操作,代码如下:
from ffmpeg import audio
audio.a_speed(input_file, output_file, speed=2)
其中,input_file是输入音频文件的路径,output_file是输出音频文件的路径,speed=2表示将音频文件的速度变为原来的2倍。通过这样的操作,即可实现音频文件的变速功能。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
