problem with recording sounds with mic

[Du DU]

Hi there！

I am using PsychoPy v1.83.04 on OS X 10.8. I set up an experiment in builder that involves using a mic to record the responses of my test persons automatically from the onset of the related items.

I receive the following error when trying to run the experiment:

############## Running: /Users/apple/Desktop/probe_mic_lastrun.py ##############

2016-04-14 16:07:16.496 python[12312:707] ApplePersistenceIgnoreState: Existing state will not be touched. New state will be written to /var/folders/13/b151w6fn5jv4_mfclzl95xt80000gn/T/org.psychopy.PsychoPy2.savedState

Traceback (most recent call last):

  File "/Users/apple/Desktop/probe_mic_lastrun.py", line 11, in <module>

    from psychopy import locale_setup, visual, core, data, event, logging, sound, gui, microphone

  File "/Applications/PsychoPy2.app/Contents/Resources/lib/python2.7/psychopy/microphone.py", line 1015

    if pyo.serverCreated():

     ^

SyntaxError: invalid syntax

This is the related code:

    # imports pyo, creates sound.pyoSndServer using sound.initPyo() if not yet created

    t0 = core.getTime()

    try:

        global pyo

        import pyo

        global haveMic

        haveMic = True

    if pyo.serverCreated():

        sound.pyoSndServer.setSamplingRate(sampleRate)

    else:

        #sound.initPyo() will create pyoSndServer. We want there only ever to be one server

        sound.initPyo(rate=sampleRate) #will automatically use duplex=1 and stereo if poss

    if outputDevice:

        sound.pyoSndServer.setOutputDevice(outputDevice)

    if bufferSize:

        sound.pyoSndServer.setBufferSize(bufferSize)

    logging.exp('%s: switch on (%dhz) took %.3fs' % (__file__.strip('.py'), sampleRate, core.getTime() - t0))

Could someone tell me how can I fix the problem since I have no idee what is wrong with the syntax?

Thanks in advance for any thoughts!!

That's quite odd. It looks like your copy of the file microphone.py has been corrupted somehow, and is missing a few lines. The syntax error is that the code has a try: statement with no corresponding except: statement.

The missing lines are

except ImportError:  # pragma: no cover
    msg = ('Microphone class not available, needs pyo; '
           'see http://code.google.com/p/pyo/')
    logging.error(msg)
    raise ImportError(msg)

You can edit the file to add those lines back in, or download the whole file from here: https://raw.githubusercontent.com/psychopy/psychopy/master/psychopy/microphone.py. Or just re-install PsychoPy if that's easier.
