如何在系统上制作不下载的discord.py音乐？

import discord
from discord.ext import commands
from discord import FFmpegPCMAudio

bot = commands.Bot(command_prefix='!')

@bot.command()
async def play(ctx):
    voice_channel = ctx.author.voice.channel
    voice_client = await voice_channel.connect()

    audio_source = discord.FFmpegPCMAudio('音乐文件的URL或本地路径')
    voice_client.play(audio_source)

@bot.command()
async def stop(ctx):
    voice_client = discord.utils.get(bot.voice_clients, guild=ctx.guild)
    if voice_client.is_playing():
        voice_client.stop()
        await voice_client.disconnect()

bot.run('你的Discord机器人Token')
