title: PyAudio Input overflowed
body: <p>I'm trying to make real-time plotting sound in python. I need to get chunks from my microphone.</p>
  
  <p>Using PyAudio, try to use </p>
  
  <pre><code>import pyaudio
  import wave
  import sys
  
  chunk = 1024
  FORMAT = pyaudio.paInt16
  CHANNELS = 1
  RATE = 44100
  RECORD_SECONDS = 5
  WAVE_OUTPUT_FILENAME = "output.wav"
  
  p = pyaudio.PyAudio()
  
  stream = p.open(format = FORMAT,
                  channels = CHANNELS,
                  rate = RATE,
                  input = True,
                  frames_per_buffer = chunk)
  
  print "* recording"
  all = []
  for i in range(0, RATE / chunk * RECORD_SECONDS):
      data = stream.read(chunk)
      all.append(data)
  print "* done recording"
  
  stream.close()
  p.terminate()
  </code></pre>
  
  <p>After, I getting the followin error:</p>
  
  <pre><code>* recording
  Traceback (most recent call last):
    File "gg.py", line 23, in &lt;module&gt;
      data = stream.read(chunk)
    File "/usr/lib64/python2.7/site-packages/pyaudio.py", line 564, in read
      return pa.read_stream(self._stream, num_frames)
  IOError: [Errno Input overflowed] -9981
  </code></pre>
  
  <p>I can't understand this buffer. I want, to use blocking IO mode, so if chunks not available, i want to wait for those chunks. But when I creating try except segment or sleep(0.1), i hear clicks, so this is not what i want.</p>
  
  <p>Please suggest the best solution for my ploblem?</p>
