以下是设备内置麦克风的有效示例: 对不起，我无法解释太多，但在这里，这是我为我的应用程序了解的内容！
here is a working example with the inbuilt microphone of your device : sorry for not being able to explain much but heres what i figured out for my app !
app.py
from flask import Flask, Response,render_template
import pyaudio
app = Flask(__name__)
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
CHUNK = 1024
RECORD_SECONDS = 5
audio1 = pyaudio.PyAudio()
def genHeader(sampleRate, bitsPerSample, channels):
datasize = 2000*10**6
o = bytes("RIFF",'ascii') # (4byte) Marks file as RIFF
o += (datasize + 36).to_bytes(4,'little') # (4byte) File size in bytes excluding this and RIFF marker
o += bytes("WAVE",'ascii') # (4byte) File type
o += bytes("fmt ",'ascii') # (4byte) Format Chunk Marker
o += (16).to_bytes(4,'little') # (4byte) Length of above format data
o += (1).to_bytes(2,'little') # (2byte) Format type (1 - PCM)
o += (channels).to_bytes(2,'little') # (2byte)
o += (sampleRate).to_bytes(4,'little') # (4byte)
o += (sampleRate * channels * bitsPerSample // 8).to_bytes(4,'little') # (4byte)
o += (channels * bitsPerSample // 8).to_bytes(2,'little') # (2byte)
o += (bitsPerSample).to_bytes(2,'little') # (2byte)
o += bytes("data",'ascii') # (4byte) Data Chunk Marker
o += (datasize).to_bytes(4,'little') # (4byte) Data size in bytes
return o
