好吧，这段代码有效：
with requests.get("https://impradio.bytemasters.gr/8002/LIVE", stream=True) as peradio:
for chunk in peradio.iter_content(chunk_size=4096):
self.s.send(chunk)
self.s.sync()
但这没有
self.stream.write(final_slice.raw_data)
active_connection_found = False
for connection in self.connections:
if connection["status"]=="connected":
connection["connection"].send(final_slice.raw_data)
connection["connection"].sync()
active_connection_found = True
if active_connection_found==False:
time.sleep(0.01)
没有错误，但我在浏览器上听不到任何音乐（正在加载）。
因此，我尝试将 final_slice 写入临时文件，然后将 f.read() 字节发送到 Icecast 服务器。 可以用，但是声音延迟很大（从 final_slice 到 final_slice），程序变慢很多。
active_connection_found = False
send_data = io.BytesIO()
final_slice.export(send_data,format="mp3")
send_data = send_data.getvalue()
for connection in self.connections:
if connection["status"]=="connected":
connection["connection"].send(send_data)
connection["connection"].sync()
active_connection_found = True
if active_connection_found==False:
time.sleep(0.01)
up 代码有效但质量低（延迟延迟）。
我能做什么？
编辑：我尝试使用的比特率为 128Kbps。
pyaudio 服务质量设置为：
#QoS settings
self.bit_rate = 128*1024 #128 kb/sec #never used this variable at the code.
self.packet_time = 93 #125 msec
self.packet_size = int(16384/4)
#self.new_sample_rate = 32768
self.new_sample_rate = 44100
self.format = pyaudio.paInt16
self.channels = 2
Edit2：我尝试发送 final_slice._data，但结果相同。
这个在QThread的run方法中

我尝试将几秒钟录制为 wav 格式，录制质量很好。
但是当我连接到 Icecast 服务器时，来自应用程序或来自浏览器的声音被中断。 ：/
编辑：如果我将 packet_time 更改为 744 毫秒。几乎一切都完美无缺。现在的问题是麦克风的声音。
提前致谢，
