Pyaudio Recorder Script Ioerror: [errno Input Overflowed] -9981

The code below is what I use to record audio until the 'Enter' key is pressed it returns an exception, import pyaudio import wave import curses from time import gmtime, strftime im

Solution 1:

I had a similar problem; there are 3 ways to solve it (that I could find)

1. set rate=24000
2. add option "exception_on_overflow=False" to the "read()" call, that is, make it "stream.read(chunk, exception_on_overflow=False)"
3. use callbacks

Here is, for your convenience, an example o "using callbacks"

#!/usr/bin/pythonimport sys, os, math, time,  pyaudio

try:
    import numpy
except:
    numpy = None

rate=48000
chan=2

sofar=0

p = pyaudio.PyAudio()

defcallback(in_data, frame_count, time_info, status):
    global sofar
    sofar += len(in_data)
    if numpy:
        f = numpy.fromstring(in_data, dtype=numpy.int16)
        sys.stderr.write('length %6d sofar %6d std %4.1f  \r' % \
                         (len(in_data), sofar, numpy.std(f)))
    else:
        sys.stderr.write('length %6d sofar %6d  \r' % \
                         (len(in_data), sofar))
    data = Nonereturn (data, pyaudio.paContinue)

stream = p.open(format=pyaudio.paInt16, channels=chan, rate=rate,
                input=True, stream_callback=callback)

whileTrue:
    time.sleep(1)
