PyAudio

[DtY]

All I need to do is read raw samples from the microphone, and I've come across PyAudio. When I go through the microhpone to wav file tutorial I get an error, I have no idea at all what it means.

Python:

>>> import pyaudio >>> p = pyaudio.PyAudio() >>> stream = p.open(format=pyaudio.paInt16,channels=1,rate=44100,input=True,frames_per_buffer=1024) >>> stream.read(1024) Traceback (most recent call last):   File "<stdin>", line 1, in <module>   File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pyaudio.py", line 564, in read     return pa.read_stream(self._stream, num_frames) IOError: [Errno Input overflowed] -9981 >>>

Anyone have any idea what's going on? I'm on Mac OS 10.6 (snow leopard), Python 2.6, btw. Another library that would let me read raw samples from a microphone would work too, it needs to at least work on OS X, and cross platform would be better.

I just installed PyAudio tonight and ran into the same problem. I was able to handle the error by wrapping the call to stream.read(chunk) in a try/except statement to catch any dropped frames gracefully, without exiting. For example:

Python:

try:       data = stream.read(chunk) except IOError:       print 'warning: dropped frame' # can replace with 'pass' if no message desired

Let me know if that works for you.

Python:

>>> import pyaudio >>> p = pyaudio.PyAudio() >>> stream = p.open(format=pyaudio.paInt16,channels=1,rate=44100,input=True,frames_per_buffer=1024) >>> stream.read(1024)

hi
don't write code step by step in the python shell.
pyaudio need to be launched from a script.

just after you create the stream, a buffer begins to keep input data.
when you read 1024, it's too late, the buffer is overflowed.

when you launch the same code from a script, the execution is faster, and may success.

you can have something like that :

Python:

while not stop:    try:         x = self.stream.read(1024)        except IOError,e:          if e[1] == pyaudio.paInputOverflowed:               print e               x = '\x00'*16*256*2 #value*format*chunk*nb_channels

Hi every one !

I am facing some peculiar problem with pyaudio!

I have used Pyaudio to implement VoIP chat module. and it is working fine as well when i connects to the internet through WiFi but when i connects two computers through LAN or Internet a dail up. I am receiving a peculiar kind of sound which is very odd .. I can hear my voice as well as that peculiar sound Can any one help me what can be the reason for it because i am stuck.

Thank you!
