Thank you for the answer i would love trying audiolab but i got this error while importing i m running python2.6
import audiolab /usr/local/lib/python2.6/dist-packages/audiolab-0.0.0-py2.6-linux-i686.egg/audiolab/soundio/play.py:48: UserWarning: Could not import alsa backend; most probably, you did not have alsa headers when building audiolab import scikits.audiolab Traceback (most recent call last): File "<stdin>", line 1, in <module> File "scikits/audiolab/__init__.py", line 25, in <module> from pysndfile import formatinfo, sndfile File "scikits/audiolab/pysndfile/__init__.py", line 1, in <module> from _sndfile import Sndfile, Format, available_file_formats, available_encodings *ImportError: No module named _sndfile*

This is done because wav file are (usually, not always) in fixed point, with values in the unsigned 16 bits int range (~ [-32768, 32768]), but when you want to do processing in floating point (as does numpy), you want the values normalized (in the [-1, 1] range). 2 * 15 gives you the normalization factor. But audiolab does this for you automatically,
