I am not an expert of Python, trying to capture/record the Audio by USB audio device. It is working fine on command terminal. But I want to make a program which just recording audio and stop when I want.
I heard ab8 Pyaudio library which has certain API to perform this job(like pyaudio.PyAudio(), pyaudio.Pyaudio.open(), pyaudio.stream, pyaudio.stream.close, pyaudio.PyAudio.terminate().....
Can somebody help to make a simple program for audio recording in Python? Thank you.

I just add relevant comments in front of commands, let me know If you want to clear more ab8 it
import pyaudio, wave, sys
CHUNK = 8192
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 10
WAVE_OUTPUT_FILENAME = 'Audio_.wav'
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels = CHANNELS,
rate = RATE,
input = True,
input_device_index = 0,
frames_per_buffer = CHUNK)
print("* recording")
frames = []
for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
data = stream.read(CHUNK)
frames.append(data)
print("* done recording")
stream.stop_stream() # "Stop Audio Recording
stream.close() # "Close Audio Recording
p.terminate() # "Audio System Close
wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()
