我不知道如何解决这个问题。请帮我 :)
我想将一台 PC 录制的声音数据发送到另一台 PC 并播放。(通过 UDP)
该程序可能正常运行,但声音包含(?)不舒服的噪音。当我尝试在一个程序序列中录制和播放声音时,它工作正常。没有噪音。如果即使在一台 PC 上使用 UDP,使用 IP 127.0.0.1,就会出现噪音。起初,我认为这是因为播放的声音在另一台 PC 中出现了,我通过制作缓冲区来修复它。它解决了一点噪音,但几乎所有的噪音仍然存在。
下面的代码是
客户
import pyaudio
import socket
from threading import Thread
frames = []
def udpStream():
udp = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
while True:
if len(frames) > 0:
udp.sendto(frames.pop(0), ("127.0.0.1", 12345))
udp.close()
def record(stream, CHUNK):
while True:
frames.append(stream.read(CHUNK))
if __name__ == "__main__":
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
p = pyaudio.PyAudio()
stream = p.open(format = FORMAT,
channels = CHANNELS,
rate = RATE,
input = True,
frames_per_buffer = CHUNK,
)
Tr = Thread(target = record, args = (stream, CHUNK,))
Ts = Thread(target = udpStream)
Tr.setDaemon(True)
Ts.setDaemon(True)
Tr.start()
Ts.start()
Tr.join()
Ts.join()

抱歉,源代码很长。随意玩这个程序。
