Du kannst die Module "pyaudio" für die Aufnahme und "pydub" für die Konvertierung nach MP3 verwenden.

import pyaudio
import wave
from pydub import AudioSegment

def record_audio(filename, duration):
    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)

    frames = []

    print("Recording...")

    for _ in range(0, int(RATE / CHUNK * duration)):
        data = stream.read(CHUNK)
        frames.append(data)

    print("Recording finished.")

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

    wf = wave.open(filename, 'wb')
    wf.setnchannels(CHANNELS)
    wf.setsampwidth(p.get_sample_size(FORMAT))
    wf.setframerate(RATE)
    wf.writeframes(b''.join(frames))
    wf.close()

def convert_to_mp3(input_file, output_file):
    sound = AudioSegment.from_wav(input_file)
    sound.export(output_file, format="mp3")

# Aufnahme starten und speichern
output_wav = "output.wav"
record_duration = 5  # Aufnahmezeit in Sekunden
record_audio(output_wav, record_duration)

# Konvertieren nach MP3
output_mp3 = "output.mp3"
convert_to_mp3(output_wav, output_mp3)
