I'm not sure if this will help, but this video [this video] seems to be pretty canny to what you are trying to achieve.

I think you probably need an additional library to achieve what you want. Here's a video tutorial on how to build an audio spectrum analyzer with Python: [this video] This was final --python2-- code from a commenter on that video (thanks user Hey Jose!) #! /usr/bin/python import pyaudio import struct import numpy as np import matplotlib.pyplot as plt import time #%matplotlib tk CHUNK = 4000 FORMAT = pyaudio.paInt16 CHANNELS = 1 RATE = 16000 p = pyaudio.PyAudio() chosen_device_index = -1 for x in xrange(0,p.get_device_count()): info = p.get_device_info_by_index(x) #print p.get_device_info_by_index(x) if info["name"] == "pulse": chosen_device_index = info["index"] print "Chosen index: ", chosen_dev

I am working with the pyaudio and matplotlib packages for the first time and I am attempting to plot live audio data from microphone input, transform it to frequency domain information, and then output peaks with an input distance. This project is a modification of the three-part guide to build a spectrum analyzer found here [this video] . Currently the code is formatted in a class as I have alternative methods that I am applying to the audio but I am only posting the class with the relevant methods as they don't make reference to each and are self-contained. Another quirk of the program is that it calls upon a local file though it only uses input from the user microphone; this is a leftover from

I am trying to get an fft plot on realtime audio using a USB microphone plugged into my raspi. I want to be able to activate an LED when a certain frequency is detected through the fft plot. I have so far tried to get just a live sound wave to be plotted but I am having trouble. I have followed this video: [this video] I have tried changing the chunk size to a greater value and a lower value but have had no success.For some reason I get the -9981 error but it takes a long time to print the error. No plot is displayed. I have even tried overclocking my Raspberry Pi to see if that would work but it still doesn't work. I was wondering if anyone else had tried something like this on their Pi and if i

Hey @AhmadMoussa, yea it definitely isn't as simple as I first thought it to be. Like I was following this on youtube [ [this video] ] to generate real-time sinwave from microphone input using pyaudio and I was wondering if I can do something similar with librosa to gather information such as the MFCC in realtime, but i don't know if this is achievable, or if there is another way. Thanks again!

Use pipwin to install it first... pip install pipwin then... pipwin install pyaudio I had this issue as well. I found this answer buried in the comments section of the following youtube video: Build an audio spectrum analyzer with python [this video]
