Integrating PyAudio with PsychoPy

Coding
1

Hey, so I’m trying to integrate PyAudio with my code to basically find the sound dB levels using the microphone and use that with my psychopy experiment. However, when I try and run the PsychoPy experiment (PsychoPyTask.zip [106.1 KB]), I get the following error:

import _portaudio as pa
ModuleNotFoundError: No module named ‘_portaudio’

I think it has to do with the fact that _portaudio is a C package that works with pyaudio, but I have found no solution to this issue online.

Is there a way to fix this issue, or accomplish the same idea using a psychopy-compatible module:

import random
import pandas as pd
import numpy as np
import time
from math import log10
import audioop
import pyaudio

#In begin routine
init_db = []

p = pyaudio.PyAudio()
WIDTH = 2
RATE = int(p.get_default_input_device_info()['defaultSampleRate'])
DEVICE = p.get_default_input_device_info()['index']
rms = 1
tm = time.time()

def callback(in_data, frame_count, time_info, status):
    global rms
    rms = audioop.rms(in_data, WIDTH) / 32767
    return in_data, pyaudio.paContinue
    
stream = p.open(format=p.get_format_from_width(WIDTH),
                input_device_index=DEVICE,
                channels=1,
                rate=RATE,
                input=True,
                output=False,
                stream_callback=callback)

stream.start_stream()
db = abs(20 * log10(rms))

#In the frames section
get_curr = time.time()
if get_curr - tm >= 0.3:
    db = abs(20 * log10(rms))
    init_db.append(db)
    tm = get_curr

Hi there, I’m running into the exact same problem- were you ever able to find a solution?
