如何在Python上将.mp3文件作为音频播放 [英] How to play .mp3 file as an audio on Python

问题描述

我正在使用Mac，并且想通过以下命令使用 os.system 播放我的.mp3文件:

I am using a Mac and want to use os.system to play my .mp3 file using the following command:

os.system('start assistant_response.mp3')

但是，我收到一个错误:

However, I am getting an error:

sh:开始:找不到命令

sh: start: command not found

有人可以建议其他命令或如何调试此命令吗?

Can someone please suggest an alternate command or how to debug this?

推荐答案

您可以尝试使用pya( https://github.com/interactive-sonification/pya )或通过pip安装.播放 mp3 并不那么简单，因为在这种情况下它需要 ffmpeg.在安装pya之前，请先安装portaudio和ffmpeg:

You can try out pya (https://github.com/interactive-sonification/pya) or install through pip. Playing mp3 is not as straight forward, as it needs ffmpeg in this case. Before you install pya, first install portaudio and ffmpeg:

brew install portaudio
brew install ffmpeg

然后

pip install pya

pya将音频编辑和回放分为2类:用于保存数组的Asig，mysound = Asig(filepath).要播放它，您需要激活服务器Aserver，并使用特定服务器调用Asig.play()，如下所示:

pya split audio editing and playback in 2 classes: Asig which holds your array, mysound = Asig(filepath). To play it, you need to activate a server Aserver, and call Asig.play() with a specific server, example below:

from pya import Asig, Aserver
s = Aserver()
s.boot()  

mysong = Asig(filepath)  
mysong.play(server=s) 

您可以对其进行基本处理，例如使其更安静或更平移:

You can do basic processing to it like make it louder quieter, or panning:

mysong.gain(db=-3).pan2(-0.5).play(server=s)  # panning between -1. (left) to 1. (right) 

您的信号数组是 mysong.sig 处的一个numpy数组，以及其他元数据，例如 mysong.sr ， mysong.samples ， mysong.channels .

You signal array is a numpy array at mysong.sig, along with other meta such as mysong.sr, mysong.samples, mysong.channels.
