Hi Arun,

Thank you for taking the time to review these patches.

Oddly enough, PyPi does not include the data folder that contains the audio 
files required for testing:

https://github.com/rabitt/pysox/tree/master/tests/data

Here is a snippet of the log showing test failures from not finding the data 
folder with the audio files:

 OSError
________________ TestTransformerVol.test_limiter_gain_vol_up_db ________________

self = <test_transform.TestTransformerVol 
testMethod=test_limiter_gain_vol_up_db>

    def test_limiter_gain_vol_up_db(self):
        tfm = new_transformer()
        tfm.vol(2.0, gain_type='db', limiter_gain=0.05)

        actual_args = tfm.effects
        expected_args = ['vol', '2.000000', 'dB', '0.050000']
        self.assertEqual(expected_args, actual_args)

        actual_log = tfm.effects_log
        expected_log = ['vol']
        self.assertEqual(expected_log, actual_log)
