无限连续不断地实时流式传输音频信号，Python [英] Continuesly streaming audio signal real time infinitely, Python

问题描述

我有一个简单的问题，在使用python音频音频流从Python的音频插孔传输音频信号时，如何使用pyaudio库继续音频流信号传输，直到选择停止"程序.

I have a simple question, while streaming audio signal from audio jack in Python, using pyaudio library how can I keep streaming the audio signal until I choose to "stop" the program.

示例:我们捕获网络摄像头的方式在无限while循环中无限帧.

Example: The way we capture our web camera frames infinitely under a infinite while loop.

例如:在此代码(摘自链接)中，流仅持续5秒钟，将进行哪些修改以达到我的目的

For example: In this code(take from link)that records the stream just for 5 seconds what will be the modification that will serve my purpose

import pyaudio
import wave
import numpy as np
CHUNK = 44100
FORMAT = pyaudio.paInt32
CHANNELS = 2
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"

p = pyaudio.PyAudio()

stream = p.open(format=FORMAT,
                channels=CHANNELS,
                rate=RATE,
                input=True,
                frames_per_buffer=CHUNK)

print("* recording") 
frames = []

for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
    data = stream.read(CHUNK)
    audio_data = np.fromstring(data, dtype=np.int32)
    print(data)
    print(audio_data)
    frames.append(data)

print("* done recording")

stream.stop_stream()
stream.close()
p.terminate()

此链接上给出的代码(处理音频数据使用回调模式)将其记录4-5秒.

Also the code given on this link (Handling audio data using callback mode) records it for 4-5 seconds.

如果有人可以帮助我，我将非常感激！

I will be really grateful if someone could help me with this!!

推荐答案

嗯，与此同时，我想出了解决方案

Well , Meanwhile I figured out solution

import pyaudio
import numpy as np
import pylab
import time
import sys
import matplotlib.pyplot as plt


RATE = 44100
CHUNK = int(RATE/20) # RATE / number of updates per second

def soundplot(stream):
t1=time.time()
data = np.fromstring(stream.read(CHUNK),dtype=np.int16)
print(data)

if __name__=="__main__":
    p=pyaudio.PyAudio()
    stream=p.open(format=pyaudio.paInt16,channels=1,rate=RATE,input=True,
                  frames_per_buffer=CHUNK)
    for i in range(sys.maxsize**10):
        soundplot(stream)
    stream.stop_stream()
    stream.close()
    p.terminate()
