[Python] How to stop recording with PyAudio on the Finally: statement

I was wondering if there is a way to stop recording and export that recording in the finally: statement in python. Example: let’s say I’m recording then all of a sudden my script crashes while I’m recording, would there be a way to stop recording and exporting that were to happen?

I’ve tried making a separate function that exports and stops recording and have that run on finally:, but that didn’t work, it just made a new file. Any help would be appreciated. My code is below:


import pyaudio
import wave
import time
import signal
from datetime import datetime

# Configuration
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 10
# Initialize PyAudio
audio = pyaudio.PyAudio()

def record_audio(filename):
stream = audio.open(format=FORMAT, channels=CHANNELS,
rate=RATE, input=True, frames_per_buffer=CHUNK)
print("Recording started")

frames = []
data = stream.read(CHUNK)
frames.append(data)

print("Recording stopped")
stream.stop_stream()
stream.close()

# Save to WAV file
wf = wave.open(filename, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(audio.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()

def main():
try:
while True:
timestamp = datetime.now().strftime("%m-%d-%Y_%H-%M-%S")
wav_filename = f"/home/henrikkoehler/Desktop/Audio_Files/{timestamp}.wav"

record_audio(wav_filename)


print(f"Audio saved to {wav_filename}")

# Wait a bit to avoid multiple recordings from a single press
time.sleep(1)

except KeyboardInterrupt:
print("Exiting...")

except:
time.sleep(1)
t_end = time.time() + 15 * 1
while time.time() < t_end:
print("Error! Restart!")

finally:
audio.terminate()

if __name__ == "__main__":
main()
