I am trying to open the microphone to record using it.

```auto
from psychopy import microphone
microphone.switchOn()
ac = microphone.AudioCapture()

```

But I get the error:

```auto
Traceback (most recent call last):
  File "/Users/ok/anaconda3/envs/myEnv/lib/python3.5/site-packages/IPython/core/interactiveshell.py", line 2885, in run_code

  File "<ipython-input-30-75b2a25e63ac>", line 1, in <module>
    ac = microphone.AudioCapture()
  File "/Users/ok/anaconda3/envs/myEnv/lib/python3.5/site-packages/psychopy/microphone.py", line 170, in __init__
    raise AttributeError('pyo server not created')
AttributeError: pyo server not created

```

Any idea why?

Thats ok, there is no solution as of yet, we are trying to gain information about why people are seeing this error, considering we cannot recreate it here in our lab.

Hi,

@oren, did you test your mic input with another software?

@oren audacity is a free and cross-platform audio editor. You can monitor and record from the microphone with it.
