PyAudio Input overflowed

Question

I\'m trying to make real-time plotting sound in python. I need to get chunks from my microphone.

Using PyAudio, try to use

import pyaudio
import wav         


        

Answer 1

My other answer solved the problem in most cases. However sometimes the error still occurs.

That was the reason why I scrapped pyaudio and switched to pyalsaaudio. My Raspy now smoothly records any sound.

import alsaaudio   
import numpy as np
import array

# constants
CHANNELS    = 1
INFORMAT    = alsaaudio.PCM_FORMAT_FLOAT_LE
RATE        = 44100
FRAMESIZE   = 1024

# set up audio input
recorder=alsaaudio.PCM(type=alsaaudio.PCM_CAPTURE)
recorder.setchannels(CHANNELS)
recorder.setrate(RATE)
recorder.setformat(INFORMAT)
recorder.setperiodsize(FRAMESIZE)


buffer = array.array('f')
while :
    buffer.fromstring(recorder.read()[1])

data = np.array(buffer, dtype='f')
