PyAudio Input Overflowed -9981 - No solution working

Question

Please do not report this question as a duplicate, because none of the already available Solution working for me, I tested them all

So, I am trying

Answer 1

Did you try setting exception_on_overflow to False? From the Pyaudio documentation:

read(num_frames, exception_on_overflow=True)

Read samples from the stream. Do not call when using non-blocking mode.

Parameters: num_frames – The number of frames to read. exception_on_overflow – Specifies whether an IOError exception should be thrown (or silently ignored) on input buffer overflow. Defaults to True. Raises IOError: if stream is not an input stream or if the read operation was unsuccessful. Return type:
string

Answer 2

elaborating on @Sidd Rajput 's answer since I did not find this clearly stated, it's not enough to set this inside your script/project, if you're importing -- pyaudio.py itself needs to be modified

def read(self, num_frames, exception_on_overflow=False):

^Line 589/590 in pyaudio.py v0.2.8:

Answer 3

Change your chunk parameter to 8192 instead of 1024. Worked for me. reference: IOError: [Errno Input overflowed] -9981

I just increased the chunk number and it appears that it works! here's my code

import pyaudio
import wave

CHUNK = 44100  #just a big number
FORMAT = pyaudio.paInt16
CHANNELS = 1 #i found that my mic has 1 channel
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"

p = pyaudio.PyAudio()

stream = p.open(format=FORMAT,
                channels=CHANNELS,
                rate=RATE,
                input_device_index=3, #found that also
                input=True,
                frames_per_buffer=CHUNK)

print("* recording")

frames = []

for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
    data = stream.read(CHUNK)
    frames.append(data)

print("* done recording")

stream.stop_stream()
stream.close()
p.terminate()

wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()
