使用 Discord.py 机器人录制音频

Question

我正在尝试制作一个 Discord 机器人，将声音从一个通道转发到另一个通道（征得被录制者的同意）。

我遇到的问题是，当多人讲话时，音频在他们之间快速切换，这使得声音断断续续且难以理解。

免责声明：我从未真正使用过音频，所以如果这是一个愚蠢的问题，但答案很明显，我深表歉意。

import discord
import pyaudio
from discord.ext import commands, voice_recv

class MyAudioSource(discord.PCMAudio):
    def __init__(self, stream):
        self.stream = stream

    def read(self):
        return self.stream.read(CHUNK)
    
    def is_opus(self):
        return False
    
class MyAudioSink(voice_recv.AudioSink):
    def __init__(self, stream):
        self.stream = stream

    def write(self, user, data):
        self.stream.write(data.pcm)
        
    def wants_opus(self):
        return False
    
    def cleanup(self):
        return

FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 48000
CHUNK = (RATE // 1000) * 20

audio = pyaudio.PyAudio()

loopback_stream = audio.open(format=FORMAT,
                             channels=CHANNELS,
                             rate=RATE,
                             input=True,
                             output=True,
                             input_device_index=2, # VAC's that lead into eachother for playback
                             output_device_index=6, # VAC's that lead into eachother for playback
                             frames_per_buffer=CHUNK)

intents = discord.Intents().all()
bot = commands.Bot(command_prefix='.', intents=intents)

@bot.event
async def on_ready():
    print("Bot is ready")

    target_channel = bot.get_channel(1262072403698257973)
    target_client = await target_channel.connect(cls=voice_recv.VoiceRecvClient)
    
    #secret_channel = bot.get_channel(1262069846259142701)
    #secret_client = await secret_channel.connect()

    my_audio_sink = MyAudioSink(loopback_stream)
    target_client.listen(my_audio_sink)

    my_audio_source = MyAudioSource(loopback_stream)
    target_client.play(my_audio_source)

    guild = discord.Object(id=1262072402997678140)
    bot.tree.copy_global_to(guild=guild)
    await bot.tree.sync(guild=guild)

bot.run("TOKEN")

编辑： 这是我正在使用的存储库： discord-ext-voice-recv

如果我没记错的话，有一个选项可以只监听一个用户，因为接收器有一个参数用户：

def write(self, user: Optional[User], data: VoiceData) -> None: self.cb(user, data)

，您也许可以列出已连接的用户并为每个用户创建一个监听接收器
