Here is my code:
import pyaudio
tim=1
chunk = 8
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 50000
p = pyaudio.PyAudio()
s = p.open(format = FORMAT,channels = CHANNELS,rate = RATE,input = True,output=True,frames_per_buffer = chunk)
d=[]
print((RATE // chunk) * tim)
for i in range(0, (RATE // chunk * tim)):
data = s.read(chunk)
d.append(data)
s.close()
p.terminate()
There is no problem, but if I want to use the variable data during the loop for, I have this error:
Traceback (most recent call last):
File "<tmp 1>", line 14, in <module>
data = s.read(chunk)
File "c:\users\tissot\miniconda3\lib\site-packages\pyaudio.py", line 608, in read
return pa.read_stream(self._stream, num_frames, exception_on_overflow)
OSError: [Errno -9981] Input overflowed
for example if i want to print data with this code:
import pyaudio
tim=1
chunk = 8
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 50000
p = pyaudio.PyAudio()
s = p.open(format = FORMAT,channels = CHANNELS,rate = RATE,input = True,output=True,frames_per_buffer = chunk)
d=[]
print((RATE // chunk) * tim)
for i in range(0, (RATE // chunk * tim)):
data = s.read(chunk)
d.append(data)
print(data) # here is the problem
s.close()
p.terminate()
In reality I would like to send it to my Arduino card as and when recording,(using: ser = serial.Serial('COM4', 115200) ser.write(data) ) but I have the same error as when I display it on the screen.
If anyone knows an answer to this question, thank you in advance.
